Doubt in static initialization and instance initialization blocks

[Satish K Patil]

Hi All,
can anybody tell me the scope of the variables declared in static initializer.

Thanks,
Satish Patil

The varaibles declared in static or instance initialization blocks will cease to exists once the block completes execution.
Thanks

But, Instance init blocks are used as a place to put code that all constructors in a class share. can you just please give eg for it.
Here,

static{
int x = 999;
}
static int x;

when i try to print 'x'. it prints 0. why not 999 ?

static{
int x = 999;
System.out.println("x:"+x); // 999
}
static int x;
 
public void someMeth() {
System.out.println("x:"+x); // 0 becuase the variable x declared is dead af
ter the block runs, Here x refers to the static member.
}

That is because you have two different 'x' variables in your class. The first is the static variable that didn't get initialized, and hence, has the value of zero. And the second is the local variable declared in your initializer, which has already been mentioned, went out of scope, after it has been set to 999.
