'''Tools Used'''
| style="border:0.035cm solid #000000;padding:0.097cm;"| For this tutorial we are using:

Ubuntu 11.10

JDK 1.6

Eclipse 3.7

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 4'''

'''Pre-requisites'''
| style="border:0.035cm solid #000000;padding:0.097cm;"| To follow this tutorial you should have knowledge of using

* '''Arithmetic''', '''Relational''' and '''Logical''' '''operators''' in '''Java'''

If not, for relevant tutorials please visit our website which is as shown.

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 5'''

'''Conditional Statements'''
| style="border:0.035cm solid #000000;padding:0.097cm;"| You may have to perform different actions for different decisions in your code.

In such cases you can use conditional statements.

A conditional statement helps to control the flow of execution of a program.

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 6'''

'''Types of Conditional Statements'''
| style="border:0.035cm solid #000000;padding:0.097cm;"| In Java we have the following conditional statements:

* If statement 
* If...Else statement 
* If...Else if statement 
* Nested If statement
* Switch statement

In this tutorial, we will learn about '''If, If...Else and If...Else If statements''' in detail.

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 7'''

'''If Statement'''

| style="border:0.035cm solid #000000;padding:0.097cm;"| '''If statement '''is used to execute a block of statements based on a condition.

It is called a '''single conditional statement.'''

It is also called '''branching''' or '''decision making statement. '''

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 8'''

'''Syntax for If statement '''

if (condition)

{

code_block<nowiki>; </nowiki>

}

// end of if construct

// program continues here''' '''
| style="border:0.035cm solid #000000;padding:0.097cm;"| Let us look at the syntax for writing '''if statement'''.

In the '''if statement, '''if the condition is '''true,''' the block is executed.

If the condition is '''false, '''the block is skipped and not executed.

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Example of If statement '''

(Minimize the slide and in the Eclipse tool, type the program according to the explanation)

class Person

{

public static void main(String args<nowiki>[]) {</nowiki>

int age<nowiki>=20; </nowiki>

if(age<nowiki><21) { </nowiki>

System.out.println("The person is Minor");

}

}

}

Highlight when you explain

Highlight '''{}'''
| style="border:0.035cm solid #000000;padding:0.097cm;"| Let us look at an example to understand how the '''If Statement''' can be used.

Let us switch to '''eclipse.'''

We will write a program to identify whether a person is '''Minor'''.

I have already created a class '''Person.'''

Now, inside the main method let us declare a variable '''‘age’''' of type '''int.'''

So type '''''int age '''is equal to'' 20.

Now, we will write an If statement as follows:

'''''if '''within parentheses '''age<nowiki> < 21</nowiki>''' curly brackets.''

Here, we are checking if '''age''' is less than '''21'''.

Whatever is inside the brackets belongs to the if block.

Inside the brackets type

'''System '''''dot '''''out '''''dot '''''println '''within brackets and double quotes''' The person is Minor.'''

Here, if '''age '''is less than '''21,''' then “'''The person is minor'''” will be displayed.

Let us '''save''' and''' run '''this file.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Highlight the output.
| style="border:0.035cm solid #000000;padding:0.176cm;"| We get the output as follows.

In this case, the person's age is''' 20''', which is less than '''21. '''

So, we got the output as “'''The person is minor'''”.

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 9'''

(Restore the slide)

'''If…Else statement '''

| style="border:0.035cm solid #000000;padding:0.097cm;"| Now, we will learn about '''if...else '''statement.

If...Else statement is used to execute alternative statements.

These are based on a single condition.

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 10'''

'''Syntax for If…Else statement '''

if<nowiki> ( <</nowiki>condition> )

<nowiki><</nowiki>statement_or_block>

else

<nowiki><</nowiki>statement_or_block>

// end of if construct

// program continues here
| style="border:0.035cm solid #000000;padding:0.097cm;"| Let us look at the syntax for writing the '''If…Else statement.'''

If the condition is True, then the statement or block of code is executed..

Else it executes another statement or another block of code.

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Example of If…Else statement'''

'''('''Please include the example in Eclipse. No need to show it on slide. Show how to run the program in Eclipse and then point to the output at the console.)''' '''

'''Type the code in Eclipse as per the explanation.'''

class Person

{

int age<nowiki>=25; </nowiki>

public static void main(String args<nowiki>[]) </nowiki>

{

if(age>21)

{

System.out.println("The person is Major");

}

else

{

System.out.println("The person is Minor");

}

}

}

Highlight as you explain.
| style="border:0.035cm solid #000000;padding:0.097cm;"| We will now see how the '''If…else statement '''can be used in a program.

Now, we will write a program to identify whether the person is '''Minor or Major'''.

So inside the '''Main''' method type

'''if '''''within brackets'' '''age''' ''greater than'' '''21''',

then ''within curly brackets'' type '''System '''''dot''''' out '''''dot''''' println '''''within brackets '''''The person is Major.'''

Then type

'''else '''''within curly brackets'' type

'''System''' ''dot '''''out''' ''dot'' '''println '''''within brackets'' '''The person is Minor.'''

Here, if the '''age''' ''is less than'' '''21''', then “'''The person is Minor'''” will be displayed.

'''Else''' the “'''The person is Major” '''will be displayed.

Now, '''save '''and''' run''' the program.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Highlight the output and explain.
| style="border:0.035cm solid #000000;padding:0.176cm;"| We get the output as follows.

Here, the person's '''age''' is '''25,''' which is greater than '''21'''.

Therefore the program will display the output as “'''The person is Major'''”.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"|
| style="border:0.035cm solid #000000;padding:0.176cm;"|

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 11'''

(Restore the slide)

'''If…Else If statement '''

| style="border:0.035cm solid #000000;padding:0.097cm;"| '''If…Else If''' statement is used to execute various set of statements.

These are based on the two given conditions.

You can also add more conditions based on your requirement.

It is also called as a''' branching '''or '''decision making statement.'''

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 12'''

'''Syntax for If…Else If statement '''

if<nowiki> ( <</nowiki>condition 1> )

<nowiki><</nowiki>Statement_or_block 1>

else if<nowiki> (<</nowiki>condition 2>)

<nowiki><</nowiki>Statement of block 2>

else

<nowiki><</nowiki>Statement_or_block 3>
| style="border:0.035cm solid #000000;padding:0.097cm;"| Let us look at the syntax for writing the '''If…Else If '''statement.

This statement initially checks for '''condition 1.'''

If''' condition 1 '''is true, it executes the '''statement 1 '''or '''block code 1'''.

Else it again checks for '''condition 2.'''

If '''condition 2''' is true, it executes '''statement 2 '''or '''block code 2'''.

Else it executes '''statement 3''' or '''block code 3'''.

In this way, we can extend the code by '''If…Else''' blocks.

These blocks can have multiple conditions.

The corresponding code will get executed until it finds the true condition.

If all the conditions are false, it will execute the final '''Else''' section.

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Example of If…Else If statement '''

(Minimize the slide and type the code according to the audio narration)

class Student

{

public static void main(String args<nowiki>[]) </nowiki>

{

int testScore<nowiki>=70; </nowiki>

if(testScore<nowiki><35) </nowiki>

{

System.out.println("C grade ");

}

else if((testScore>=35)&&(testScore<nowiki><=60)) </nowiki>

{

System.out.println("B grade");

}

else

{

System.out.println("A grade");

}

}

}

| style="border:0.035cm solid #000000;padding:0.097cm;"| We will see how the '''If…Else If statement '''can be used in a program.

So switch to Eclipse.

I have already created a class named Student.

Let us write a program to identify grade of a student.

This is done based on the score percentage.

In the''' Main''' method, type '''int''' ''space''''' testScore''' ''equal to''''' 70''' ''semicolon.''

The input variable named ‘'''testScore'''’ is used to get the score percentage.

Then type''' if''' ''within brackets'' '''testScore''' ''is less than'' '''35, '''''within curly brackets '''''System '''dot''' out '''''dot println within brackets and double quotes''''' C grade '''''semicolon'''''.'''

If the''' testScore''' is less than '''35''', then the program displays "'''C Grade'''".

Next line type '''else '''

Then next line type '''if'' '''within brackets''''' testScore '''''greater than or equal to'' '''35 '''and '''testScore '''''less than or equal to '''''60.'''

Here, the program will check for the second condition in the '''Else If''' section.

If the '''testScore''' is between '''35 '''and '''60''' then the program displays "'''B Grade'''".

Next line type '''else''''' within brackets'' type '''System''' ''dot '''''out''' ''dot'' '''println''' ''within brackets and double quotes'' '''A grade''''' semicolon''.

Finally, if both the conditions are '''False''', the program displays “'''A Grade'''".

Now, let us '''save''' and '''run''' this code.

.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Highlight the output and explain
| style="border:0.035cm solid #000000;padding:0.176cm;"| We get the output as follows.

In this program, the student’s '''testScore''' is '''70''' .

So the output will be displayed as “'''A Grade'''”.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Change testScore<nowiki>=55;</nowiki>
| style="border:0.035cm solid #000000;padding:0.176cm;"| Let us change the''' testScore''' to''' 55.'''

Now, '''save''' and '''run''' this program.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Highlight the output as you explain.
| style="border:0.035cm solid #000000;padding:0.176cm;"| We get the output as follows.

In this case, the output will be displayed as “'''B Grade'''”.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| else if((testScore>=60)&&(testScore<nowiki><=75)) </nowiki>

{

System.out.println("O grade");

}

Highlight as you explain.
| style="border:0.035cm solid #000000;padding:0.176cm;"| We can also increase the number of conditions.

Let us add one more condition after the “'''B grade'''” output section.

So type here, '''if''' ''within brackets''''' testScore''' ''greater than or equal to'' '''60 '''and''' testScore''' ''less than or equal to'' '''75.'''

Then within curly brackets type '''System '''''dot '''''out''' ''dot '''''println''' ''within brackets and double quotes''''' O grade''' ''semicolon''.

Here if the '''testScore''' is between '''60''' and '''75''' then the program will display "'''O Grade'''".

Now, change the '''testScore''' of the student to''' 70'''.

Now, '''save '''and''' run''' the file.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Highlight the output.
| style="border:0.035cm solid #000000;padding:0.176cm;"| We get the output as follows.

The program will display the output as “'''O grade'''”.

It is not “'''A grade'''” as it displayed before.

The program will display “'''A grade'''” for the '''testScore''' greater than '''75.'''

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 13'''

'''Points to Remember'''
| style="border:0.035cm solid #000000;padding:0.097cm;"| While coding conditional structures:

* Always remember to add a semicolon while terminating a statement.

* But don’t add semi-colons after the condition.

* Add the block of code within curly braces.
* Curly braces are optional if the block contains a single statement.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"|
| style="border:0.035cm solid #000000;padding:0.176cm;"|

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 14'''

'''Summary'''
| style="border:0.035cm solid #000000;padding:0.097cm;"| We have come to the end of this tutorial.

In this tutorial, we:

* Explained conditional statements
* Listed the types of conditional statements
* Used conditional statements: '''if, if...else and if...else if''' in Java programs.

|-
| style="border:0.035cm solid #000000;padding:0.097cm;"| '''Slide 15'''

'''Assignment'''

| style="border:0.035cm solid #000000;padding:0.097cm;"| Now take an assignment on writing java programs using conditional statements: '''if, if...else and if...else if '''statements.
