below is a question from Marcus Green's site.
Given the following code what will be the output?
class ValHold{
public int i = 10;
}
public class ObParm{
public static void main(
String argv[]){
ObParm o = new ObParm();
o.amethod();
}
public void amethod(){
int i = 99;
ValHold v = new ValHold();
v.i=30;
another(v,i);
System.out.println(v.i);
}//End of amethod
public void another(ValHold v, int i){
i=0;
v.i = 20;
ValHold vh = new ValHold();
v = vh;
System.out.println(v.i+ " "+i);
}//End of another
}
1) 10,0, 30
2) 20,0,30
3) 20,99,30
4) 10,0,20
who can tell me which answer is correct and why is it correct?
Thank a lot.
