Not a mutable one.
Try this one:
public class Test
{
static public void main(String argv[])
{ int a=3;
int b=4;
Int aa= new Int(a);
Int bb= new Int(b);
swap(aa, bb);
System.out.println("aa="+aa.intValue());
System.out.println("bb="+bb.intValue());
}
static void swap(Int a1, Int b1)
{
int tmp = a1.intValue();
a1.setIntValue( b1.intValue() );
b1.setIntValue( tmp );
}
}
class Int
{
int value = 0;
public Int( in |
