1.What is Instance Block?
Instance Initialization Block(IIB) is group of code enclosed within curly braces { } which is used to initialize an object during object creation.
2.Purpose of Instanse Block
there are two purposes of Instanse Block in java
1.Instance block can be used for object initialization..
This means, we can use Instance block for object initializationbut generally we don't used instance block for object initialization because if we use instance block for object initialization then all the objects will initialized with the same values which is totally useless.
2.Instance block can also be used to write code/ logic which is common to all objects which is executed automatically when object created and this is a main purpose of Instanse Block in Java.and this is a main purpose of Instanse Block in Java.
3.Syntax:
syntax is of Instanse Block is very simple..
We have to just write code inside opening and closing curly bracess.
Instance block doesn't have any name i.e it is name- less
{
// Code
}
4. Important Points about IIB:
1.In single class their can be multiple Instance block and they will execute in the same order as they written.and they will execute in the same order as they written.
2.Instance Block always executed before the Constructor..
3. Instance block automatically get execute / run when object is created.
