一个简单传值程序测试

public class ListTest {   
  
    public static void main(String[] args) {   
        List orgList = new ArrayList();   
        transList(orgList);   
        for (Object o : orgList) {   
            System.out.println(o.toString());   
        }   
  
    }   
  
    static void transList(List orgList) {   
        orgList.add("aa");   
        orgList.add("bb");   
    }   
  
}  

结果：aa  bb
