高手，小弟的代码如下：
现在，
import java.awt.Rectangle;点击运行后得到的结果为：
import java.awt.event.ComponentAdapter;
import java.awt.event.ComponentEvent;

希望得到高手的指点：
小弟的这个故障，错在哪里？如何修改？
------解决思路----------------------
在工程中找到前面带红叉的类，然后将里面的错误解决掉就可以了。
------解决思路----------------------
这个意思是方法未定义，检查一下，是不是这个方法内部有错。
------解决思路----------------------
很明显的错误方法未定义
------解决思路----------------------
这错误很明显吧……少个方法，加上试试看。
自己动手，丰衣足食。
