class B { int x,y; int z; z=x*y; void show() { System.out.println(z); } } class A { public static void main(String as[]) { B b=new B(); b.show(); } }

You can't have statements in the class body (z=x*y;). You have (at least) two options:

int z = x * y;
use initializer block
```
{ z = x * y; } 
```

These are virtually the same. I'd prefer the first option (cleaner) See here

z=x*y; you cant do it here. put it inside constructor

class B { int x,y; int z; //z=x*y; //you cant do it here. where are you getting x and y value by the way??? public B() { //x and y values should be set 'somehow' before this z = x*y; } void show() { System.out.println(z); } }

I think that your problem is in these lines:

int z; z=x*y;

This first line is perfectly fine - it declares a class instance variable called z of type int. This second line, however, is the source of your problem. In Java, it's illegal to have code in a class outside of a class method or static initializer. In this case, the statement z = x * y; is legal Java code, but it has to be inside of a method.

To fix this, you can move this code into a constructor or some other method.
