int a;
a=1;
}
but following code working fine:
class A{
int a=1;
}

What error is java giving you?

[danielstoner]

Come on You cannot do a=1; in the class body. You have to put that in a method, static bloc or initialize the variable on the same line where you declare it like in second example.

Yes, according to the code segment you have to use non-static initialization block as follows.

Code:

class A {
   int a;

   {
        a = 1;
   }
}

In the first example, "a=1" is an assigment sentence, and assigment sentences only are allowed inside methods.

The second one is an initializer declaration and can be on classes attributes or local variables.

Inside installation blocks too. Normally we don't call them as methods.
