Hi:
Can someone describe to me step by step how references passed in the following code result in the output:
15 0
20

public class Test
{
public static void main(String args[])
{
Test t = new Test();
t.first();
}
public void first()
{
int i = 5;
Value v = new Value();
v.i=25;
second(v,i);
System.out.println(v.i);

}
public void second(Value v, int i)
{
i = 0;
v.i =20;
Value val=new Value();
v= val;
System.out.println(v.i +" " + i);
}

}
class Value
{
public int i = 15;
}
