E.要求：
(1) Monkey类中有个构造方法：Monkey (String s),并且有个public void speak()
方法,在speak方法中输出"咿咿呀呀......"的信息.
中输出"小样的,不错嘛！会说话了！"的信息.
的信息.
能.、
复制代码
package zhongqiuzuoye;
public class Monkey {
Monkey(String s) //构造
{}
public void speak()
{
System.out.println("咿咿呀呀......");
可运行的：
import java.awt.*;
import java.awt.event.*;
public class BackJFrame extends Frame{
public BackJFrame(){

addWindowListener(new WindowAdapter()

{System.exit(0);}
} );
public static void main(String args[]){
new BackJFrame();
