Should be clearer

Question

class A {

public static void main(String[] args) {
B obj = new B();

obj.setV1(50);
System.out.println(obj.getV1());

}

}

class B {

private int v1;

public void setV1(int x) {
this.v1 = x ;
}

public int getV1() {
return v1;
}
}

Answer 1

Some like this?

class A{
public static void main (String [] x)
B b = new B(50);
System.out.println(b.getV1);
}
}
class B{
private int v1;
B(int v1) {
this.v1 =v1;
}
public int getV1() {
return v1;
}
}
