Java 用螺纹重新喷漆
我有2个JC组件，动画和园丁面板。我在jlayeredpane中有它们，但动画类是一个始终保持移动的角色。当我在main方法中调用repaint时，它是非常波动和缓慢的。因此，我创建了一个名为Update的新类，它将实现runnable并启动一个只调用animation.repaint（）的新线程。但它仍然是阴沉和波涛汹涌的。有什么帮助吗Java 用螺纹重新喷漆,java,multithreading,swing,jcomponent,Java,Multithreading,Swing,Jcomponent,我有2个JC组件，动画和园丁面板。我在jlayeredpane中有它们，但动画类是一个始终保持移动的角色。当我在main方法中调用repaint时，它是非常波动和缓慢的。因此，我创建了一个名为Update的新类，它将实现runnable并启动一个只调用animation.repaint（）的新线程。但它仍然是阴沉和波涛汹涌的。有什么帮助吗 public class Driver { public static void main(String[] args) { Eve
