| style="border:1pt solid #000000;padding:0.097cm;"| '''Description'''

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Slide 1

'''Welcome'''
| style="border:1pt solid #000000;padding:0.097cm;"| Welcome to the spoken tutorial on '''for loop'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Slide 2

'''Learning Outcomes'''
| style="border:1pt solid #000000;padding:0.097cm;"| In this tutorial, you will learn how to use the '''for loop in Java.'''

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Slide 3

'''Tools Used'''
| style="border:1pt solid #000000;padding:0.097cm;"| For this tutorial we are using

* '''Ubuntu 11.10''',
* '''JDK 1.6''' and
* '''Eclipse 3.7.0'''

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Slide 4

'''Prerequisites'''
| style="border:1pt solid #000000;padding:0.097cm;"| For this tutorial, you should have knowledge on '''relational operators in Java.'''

If not, please go through the tutorials on these topics available at our website [http://spoken-tuitorial.org/ http][http://spoken-tuitorial.org/ ://][http://spoken-tuitorial.org/ spoken][http://spoken-tuitorial.org/ -][http://spoken-tuitorial.org/ tutorial][http://spoken-tuitorial.org/ .][http://spoken-tuitorial.org/ org][http://spoken-tuitorial.org/ .]

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Slide 5

'''Syntax'''
| style="border:1pt solid #000000;padding:0.097cm;"| Here is the syntax of the '''for loop'''.

Now, let us try out an example in '''Eclipse.'''

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Minimize Slides and open Eclipse

Eclipse should contain the following code

'''public class ForLoopDemo{'''

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

'''}'''

'''}'''
| style="border:1pt solid #000000;padding:0.097cm;"| We have the skeleton required.

We have a '''class''' named '''ForLoopDemo'''.

Let us add the '''for loop''' inside the '''main method'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Inside the main function, type

'''int i<nowiki>;</nowiki>'''

'''for (i = 0; i<nowiki> < 10; </nowiki>i = i + 1)'''

Highlight''' '''when you explain.
| style="border:1pt solid #000000;padding:0.097cm;"| Inside the main function, type '''int i '''''semicolon''.

Then type '''for '''''within brackets'' '''i '''''equal to''''' 0 '''''semicolon'' '''i '''''less than '''''10''' ''semicolon''''' i '''''equal to'' '''i '''''plus '''''1'''.

This statement decides how the loop is going to progress.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Highlight i = 0
| style="border:1pt solid #000000;padding:0.097cm;"| This is the starting condition for the loop.

This condition allows the variable to be initialized.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight i<nowiki> < 10</nowiki>
| style="border:1pt solid #000000;padding:0.176cm;"| This is the loop running condition.

If the condition is true then the for block will be executed.

Else it will be ignored.

That means when i becomes more than or equal to 10, the block is not executed.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight i = i + 1
| style="border:1pt solid #000000;padding:0.176cm;"| This states how the loop variable is going to change.

Here, the value of i starts with 1.

It keeps increasing by 1 for every iteration of the loop until it becomes 10.

Now let us do something with i.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Change for (i = 0; i<nowiki> < 10; </nowiki>i = i + 1) to for (i = 0; i<nowiki> < 10; </nowiki>i = i + 1) {

System.out.println( i * i );

}

Highlight the println statement and explain.
| style="border:1pt solid #000000;padding:0.097cm;"| Now, open curly brackets.

Next line type '''System''' ''dot''''' out '''''dot '''''println''' within brackets '''i''' ''into'' '''i'''.

This will print the square of each number from 1 to 10.

Let us see the output.

So '''save''' and '''run''' the file.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Save and run. Point to output
| style="border:1pt solid #000000;padding:0.097cm;"| As we can see, the loop ran over numbers from 1 to 10.

The square of the number has been printed in each iteration.

Now let us print all the 2 digit numbers that are multiples of 3 or 5.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Change '''i = 0''' to '''i = 10'''
| style="border:1pt solid #000000;padding:0.097cm;"| So, '''i '''should have values from 10 to 99.

So change''' i''' ''equal to'' '''0''' to '''i '''''equal to '''''10'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Change '''i<nowiki> < 10</nowiki>''' to '''i<nowiki> < 100</nowiki>'''
| style="border:1pt solid #000000;padding:0.097cm;"| Change '''i '''''less than'' '''10''' to '''i '''''less than'' '''100'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Change '''System.out.println( i * i )''' to

'''if ((i % 3 == 0) || (i % 5 == 0)){'''

'''System.out.println(i);'''

'''}'''
| style="border:1pt solid #000000;padding:0.097cm;"| Delete '''System''' ''dot'' '''out''' ''dot'' '''println '''within brackets '''i''' ''into'' '''i'''.

We print the number only if it is a multiple of 3 or 5.

So type,

'''if '''within brackets '''i''' ''mod'' '''3''' ''double equal to'' '''0 '''or''' i '''''mod'' '''5 '''''double equal to '''''0'''.

This statement checks whether '''i '''is divisible by '''3 '''or by '''5'''.

Then, next line type '''System''' ''dot'' '''out '''''dot'' '''println''' within brackets '''i'''.

Now, let us see the output.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Save and run. Highlight the output
| style="border:1pt solid #000000;padding:0.097cm;"| We can see that the numbers are either multiples of 3 or of 5.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Minimize the '''Eclipse''' window and switch to slides.

Slide 6

'''Summary'''
| style="border:1pt solid #000000;padding:0.097cm;"| We have come to the end of this tutorial.

In this tutorial we have learnt how to '''use for loop in java.'''

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Slide 7'''Assignment'''
| style="border:1pt solid #000000;padding:0.097cm;"| A three digit number is called Armstrong Number if it is equal to the sum of cubes of its digits.

For example, 153 is equal to 1 cube plus 5 cube plus 3 cube.

Find all such 3 digit numbers.
