基础测试.
大家如果都不测试.说出程序的执行流程,及输出结果,并分析原因.

LZ能给解释一下吗??? 没弄明白为什么结果是这样的.......
------解决方案--------------------
学习 up up 正在学swing 呵呵 初学 能给解释一下吗?? 明天上课我好吹一下 .....
------解决方案--------------------
JFrame继承自Frame，有什么不对么？
------解决方案--------------------
我以为是
java.awt.Frame
javax.swing.JFrame
没想到是：
javax.swing.JFrame
javax.swing.JFrame
和下面这个例子一样：
class People
{}
class Student extends People
{}
public class Client
{
public static void main(String args[])
{
People p1 = new Student();
System.out.println( p1.getClass().getName() );
Student p2 = new Student();
System.out.println( p2.getClass().getName() );
}
}
结果：
execices.Student
execices.Student
------解决方案--------------------
看一下就知道了
public final Class <? extends Object> getClass()

Returns the runtime class of an object. That Class object is the object that is locked by static synchronized methods of the represented class.

Returns:
The java.lang.Class object that represents the runtime class of the object. The result is of type Class <? extends X> where X is the erasure of the static type of the expression on which getClass is called.
