what is the output?

A obj=new A(); obj.x=15 Foo(obj); System.out.println(obj.z); System.out.println(obj.y); B obj2 = new B(7); Foo(obj2); obj2.w=obj.x+obj2.y: System.out.println(obj2.w); } public static void Foo(A 0){ O.Z=--O.X+o.y- ) //--- public class A int x,y,z int k=80; public Act System.out.println(k): this.k=40; this.y=6; } //--- public class B extends Al int w; int k=150; public Al int b) super.k=b; System.out.println(this.k); )
