Given the command line java Pass2 and： 
public class Pass2 { 
public void main（String [] args） { 
int x=6； 
Pass2 p = new Pass2（）； 
p.doStuff（x）； 
System.out.print（” main x = “+ x）；
} 
void doStuff（int x） { 
System.out.print（” doStuffx = “+ x++）； 
} 
} 
What is the result？（） 

Given a correctly compiled class whose source code is： 
package com.sun.sjcp； 
public class Commander { 
public static void main（String[] args） { 
// more code here 
}

Assume that the class file is located in /foo/com/sun/sjcp/， the current directory is /foo/， and that the classpath contains “.“ （current directory）. Which command line correctly runs Commander？（）
