'''Static Blocks'''

* A '''Static block '''is mostly used for

initializing values of '''static variables'''

* A '''static block''' is declared using the

'''static''' keyword

* '''Static blocks''' are executed when the

class is loaded in memory
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Let us learn about '''static blocks'''.

'''Static Block - Sample Code'''

Highlight the code

static {

count=100;

orgname="IITM";

}
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Let us see how to use a''' static block '''with an example'''.'''

The variables '''orgname''' and''' count''' shown in this example are '''static variables.'''

Here we can see that, there is a block of code within the curly brackets prefixed by the '''static''' keyword.

This block of code is a '''static block''' which is used to initialize the values of''' orgname '''and '''count.'''

Here we can see that '''orgname''' is initialized with a value '''IITM '''and '''count''' with a value '''100.'''

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| '''Slide 7'''

'''Static Blocks'''

* Static blocks are invoked before '''constructors '''
* Instance variables cannot be accessed''' '''inside''' static blocks '''

| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| If there are '''static blocks''' in a program, they are invoked before '''constructors.'''

We cannot access '''instance variables''' inside a '''static block.'''

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| In Eclipse IDE, create a project called '''StaticBlockDemo'''

| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Now, we will switch to''' Eclipse''' and create a new project called '''StaticBlockDemo'''.

Inside this project, we will create the necessary classes to demonstrate the usage of''' Static Blocks.'''

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Right click on '''src''' folder and click '''New'''-> '''Class'''

Type the name of the class as''' StudentEnroll'''.

Type the name of the class as''' StudentEnroll''' and press '''Enter'''.

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| //copy the code below

private String id, name, branch;

private static int count;

private static String orgname;
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Now type the following code to represent the''' StudentEnroll''' class.

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Highlight '''count''' and''' orgname'''
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Note that there are two''' static variables count''' and''' orgname'''.

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| click on''' Source ->''' and select''' Generate Constructor using Fields'''
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Now click on''' Source ->''' and select''' Generate Constructor using Fields'''

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Delete the '''super''' keyword
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Delete the '''super''' keyword from the generated code.

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| //Copy paste the following code

System.''out''.println("constructor invoked");

| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| We want a message to be printed whenever the '''constructor''' is invoked.

So inside this '''constructor''', type the following code to print “'''Constructor invoked'''”.

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| //Copy paste the following code

public void showData()

{

System.''out''.println(id+" "+name+" "+branch+" "+count+ " "+ ''orgname'');

}
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Now we will add a method''' showData'''( ) to this class to print the values of the variables.

So type the following code

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| //Copy paste the code

orgname="IITM";

}
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Now we will add a static block to initialize the values of '''count''' and '''orgname.'''

Type the following code.

We have already seen this code earlier in a slide.

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Highlight''' count''' and''' orgname'''
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| This static block initializes the values for '''count''' and '''orgname''' as '''100 '''and '''IITM''' respectively.

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| //Copy paste the code inside the static method

System.out.println("static block-1 is invoked");
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Inside this '''static block,''' type the following code to print “'''static block-1 is invoked'''”.

|-

click '''New-'''> '''Class''' and then type name as''' Demo'''.
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Now we will add one more class containing the '''main''' method

So right click on the''' default package,''' click '''New'''-> '''Class''' and then type the name as''' Demo.'''

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Type '''main''' and then press''' ctrl+space'''
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Inside this class we will have the '''main''' method.

Type '''main''' and then press''' ctrl+space''' to generate the''' main method.'''

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| //Copy the code

StudentEnroll s1=new StudentEnroll("IT101","ADIL","IT");
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| We will create an object of''' StudentEnroll class.'''

Type the following code to create an object''' s1.'''

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| type '''s1.showData();'''
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Now let us invoke the''' showData''' method to print the values.

Type '''s1.showData() semicolon'''

| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Now let us run the '''Demo''' program.

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Highlight “static block-1 is invoked”

“constructor invoked”

Highlight '''100''' and '''IITM'''

| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| We can observe that '''static block''' is invoked before the '''constructor'''.

The values of '''count''' and '''orgname''' are initialized as defined in the '''static block'''.

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Go to '''StudentEnroll '''class.

| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Type '''id=IT01;'''

| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Let us see what happens if we initialise the value of '''id '''inside the''' static block'''.

Inside the static block type,

'''id equals IT01 semicolon'''

|-
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| Show the error message
| style="border:1pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.173cm;padding-right:0.191cm;"| We can see that an error comes up.

It indicates that an '''instance variable''' cannot be accessed inside a '''static block'''

|-
