| 00:02
| Welcome to the Spoken Tutorial on '''Non-static block '''in '''java'''.

|-
| 00:06
| In this tutorial we will learn

|-
| 00:08
| About '''non-static''' '''block'''

|-
| 00:10
| When a '''non-static block '''executed?

|-
| 00:13
| Simple example of '''non-static block'''

|-
| 00:16
|And Why we need '''constructors'''?

|-
| 00:18
| Here we are using

* Ubuntu version 11.10
* Java Development Environment jdk 1.6
*And Eclipse IDE 3.7.0

|-
| 00:26
|To follow this tutorial you must know

|-
| 00:29
|How to create a '''constructor''' in '''Java''' using '''Eclipse'''

|-
| 00:33
| If not, for relevant tutorials please visit our website which is as shown,

('''http'''://'''www.spoken'''-'''tutorial.org''')

|-
| 00:38
| Now we will see what a '''non-static block''' is.

|-
| 00:42
| Any code written between two curly brackets is a '''non-static block'''.

|-
|00:46
| We can see the syntax here.

|-
| 00:51
| When is a '''non-static block''' executed ?

|-
| 00:54
|A '''non-static block''' is executedfor each object that is created.

|-
| 00:59
| It executes before the '''constructor''''s execution.

|-
| 01:04
| It can initialize''' instance member variables '''of the class.

|-
| 01:08
| Any other execution like calculation could also be given in the block.

|-
| 01:14
| Now, let us switch to '''Eclipse''' and try to use a '''non-static block.'''

|-
| 01:23
| I have already opened a class named '''NonStaticTest''' in '''Eclipse.'''

|-
| 01:28
| I also have a created a '''class '''named '''A''' .

|-
| 01:33
| Now inside '''class''' '''A ''', I will first create a variable of type '''int'''.

|-
| 01:38
| So type '''int''' a semicolon, then press ''Enter''

|-
| 01:46
| Within curly brackets type '''System''' ''dot '''''out''' ''dot'' '''println''' within brackets and double quotes '''Non static''' '''block of an instance of Class A '''''semicolon''.

|-
| 02:12
| Then type '''System '''''dot'' '''out''' ''dot '''''println''' within brackets and double quotes '''The value of a''' is ''plus '''''a '''''semicolon''.

|-
| 02:32
| Now we will declare a '''constructor'''.

|-
| 02:36
| So type '''public A''' ''opening and closing brackets'', open the ''curly brackets'' press '''Enter'''.

|-
| 02:51
| Then type '''System''' ''dot '''''out '''''dot'' '''println''' within brackets and double quotes '''Constructing object of type A''' semicolon.

|-
| 03:11
| Then type '''System''' ''dot'' '''out '''''dot '''''println''' within brackets and double quotes '''The value of a '''is ''plus'' '''a '''''semicolon''.

|-
| 03:35
| Now save this file.
|-
| 03:44
| Inside '''class NonStaticTest''' in''' Eclipse '''let us create an '''object '''of the '''class A'''.

|-
| 03:53
| So type '''A''' ''space '''''a1''' ''equal to''''' new''' ''space'' '''A''' opening and closing brackets semicolon

|-
| 04:08
| Next line we will create one more object of class '''A'''.

|-
| 04:12
|So type '''A''''' space'' '''a2''' ''equal to'' '''new '''''space'' '''A''' opening and closing brackets semicolon.

|-
| 04:25
|Now Save and run the file. So press '''Ctrl &S''' and '''Ctrl &F11 '''keys

|-
| 04:32
| We get the output as follows:

|-
| 04:35
| As we can see when the first''' object '''is created, the '''non-static block''' is executed.

|-
| 04:45
| '''non-static block''' of an''' instance of class A ''' and the''' instance variable A '''is initialized to '''0'''.

|-
| 04:53
| Only after that the '''constructor''' is executed. Constructing object of type A

|-
| 05:02
| And here the''' instance variable''' is again initialized to '''0'''.

|-
| 05:07
| Then again when the second '''object''' is created, the '''non-static block''' is executed.

|-
| 05:16
| This process is repeated.

|-
| 05:20
| We can have multiple '''non-static blocks''' in a '''class'''.

|-
| 05:25
| In this case they execute in the sequence in which they appear in the '''class.'''

|-
| 05:30
| We can try that now.

|-
| 05:34
| Include one more block after the first one in class A.

|-
| 05:43
| So again type inside curly brackets.

|-
| 05:47
| '''System''' ''dot '''''out''' ''dot'' '''println''' within brackets and double quotes '''Second''' '''Non static''' '''block of an instance of Class A '''''semicolon''.

|-
| 06:08
| Then type '''System '''''dot'' '''out''' ''dot '''''println''' within brackets and double quotes '''The value of a''' is ''plus '''''a '''''semicolon''.

|-
| 06:30
| Now save this file ,press''' Ctrl & S key ''' simultaneously then press ''' Ctrl & F11 ''' to run the program.

|-
| 06:44
| We get the output as follows.

|-
| 06:48
| we see that after the first block is executed, the second is executed.

|-
| 06:58
| Only then the '''constructor''' is executed.

|-
| 07:07
| Now you might feel why do we need '''constructors.'''

|-
| 07:10
| The answer is we don't need the '''default constructor'''.

|-
| 07:15
| But the '''non-static block''' cannot be '''parameterized'''.

|-
| 07:18
| You cannot have''' objects''' taking values from out side.

|-
| 07:22
| So '''non-static block '''is not a substitute for '''constructor.'''

|-
| 07:27
| So let us summarizes

|-
| 07:29
| In this tutorial we learnt :

|-
| 07:32
| About '''non-static block''' and how to use this block.

|-
| 07:35
| For self assessment,

|-
| 07:36
| create a '''class '''named '''B.'''
|-
| 07:39
| Create a '''non-static block''' and a '''constructor''' as shown in the tutorial.

|-
| 07:44
| Create an '''object''' of '''class B''' in the '''class NonStaticTest '''already created'''.'''

|-
| 07:49
| Check the output.
