Static Initializer + Variable Declaration

Hi,

I have one doubt regarding the Static Initiliser block, and the variable declared in that block.

I have 2 different scenario:
1)
static{
static int x = 999;
System.out.println("x:"+x);
}
2)
static int x;
static{
int x = 999;
System.out.println("x:"+x);
}
The Scenario 1 gives the compile time error, while scenario 2 not.

In the first Scenario we are declaring the static variable inside the Static block, while in the second one we are declaring the static variable outside the Static block and using them.

Why we can't declare the static variable inside static block.
What might be the problem?

You cannot declare static variables inside a static initializer block, just like you cannot declare static variables inside a method.

You must declare member variables (static or not) at the class level, not inside a block of code like the static initializer block.
