Execution sequence

[Rahul Kumar]

Hi all,,


I want to know the execution sequence..

Whethere the sequence i hav written is correct or not..
1) First static variables
2) Static block
3) Main method
4) Non Static variables..

If anybody has any good link kindly share it...

Hi,

The Sequence is right but there is one more thing you might want to know
that is , after main method the non-static blocks(eg., blocks like {System.out.println();} ) are executed.Also, first the static variables are initialized with their default values(say 0 for int) then static blocks are executed in order of apperance and then the static variables are executed in order of their appearance

See the code below which shows the same.

class TestBraces 
{
{ 
System.out.println("one");
}
static {
x = 8;
System.out.println("static one"); 
}
static int x = 5;
public static void main(String[] args) 
{
System.out.println(x);
new TestBraces().run();      
}
 
private TestBraces(){
 
{ System.out.println("two"); } 

}
 
{ System.out.println("three"); }
 
    static
{ System.out.println("static two");
}
 
public void run()
{System.out.println("hmm...");
}
}

and the o/p is:

---------- o/p ----------
static one
static two
5
one
three
two
hmm...


Bye & Regards,
Praveen
