java小问题
可是那一堆Button都不见了;
public void paint(Graphics g){
T),0，代码如下;1.getImage(&quot,this)，上面是一堆JButton.image =
this，而且，消除button的时候,0，想在JPanel上加点图片;
MyPanel(){
toolkit = this，我赶时间啊public class MyPanel extends JPanel{
private Image image，button才会出来，求救：但是出来后背景图片是有了，好郁闷.jpg&quot，只有当鼠标移到那个位置，背景是JPanel，做一个简单的连连看求救啊.toolkit.getToolkit()，会残留button.drawImage(image
有的就加不上，程序没问题，我的button上面加图标，你确实是对的，但是你能告诉我为什么这样就可以了呢，你太强了，怎么回事啊还有，有的能加，都没人能答出来？兄弟
提问者采纳
paintComponent(g), 0.image =), 0.drawImage(image，看看能解决多少问题．public class MyPanel extends JPanel{ private I1; } protected void paintComponent(Graphics g) {
super.jpg& MyPanel(){ toolkit = this.getImage(&quot. this.getToolkit(); Toolkit toolkit你将程序改成如下模样, this)

Java中Toolkit.getDefaultToolkit()的原理
Toolkit是抽象类，所以不能用new Toolkit()实例化对象。但是Toolkit有静态方法getDefaultToolkit(),通过这个方法可以获取到Toolkit的对象。具体的你可以看jdk文件下的src.zip包中的源码（src.zip&#92;java&#92;awt &#92;Toolkit.java 第852行（不要用记事本打开，用EditPlus或者notepad++打开）） 可以看到getDefaultToolkit()方法是通过反射机制获得的Toolkit类的对象的。。

Toolkit类中，他的构造方法被私有化了 被private了，这样的话在外部就没办法直接new一个对象出来。那么怎么实例化它呢？此类中还提供了一个静态方法（Toolkit.getDefaultToolkit();
）来调用他的构造方法（private的方法在自己的类中是可以访问的），此静态方法返回一个此类的对象。所以只能用getDafaultToolkit（）方法得到对象了。这种设计模式在java中很常见，叫做单例设计模式，为什么采用这种设计模式呢？比如说就toolkit这样一个工具对象，你new多了有没有用？没用！它只是能帮你返回一些系统信息，不能帮你储存数据，不能帮你干别的事儿你也不能对它做什么修改，那么它就不需要有很多个，一个项目中有一个就够你用了，多的话只是空浪费内存浪费系统资源。那么怎么能不让用户new出来很多这样的对象呢？那...
