Question

在网上找了个java的代码，如何在里面添加一个播放背景音乐的类？

具体说一下，完全不知道怎么用，java刚学。有任何要注意的请说明下。

Answer 1

package test;

import javax.swing.UIManager;
import java.awt.*;

public class TestPlayer {
boolean packFrame = false;

public TestPlayer() {
TestFrame frame = new TestFrame();
frame.validate();
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension frameSize = frame.getSize();
if (frameSize.height > screenSize.height) {
frameSize.height = screenSize.height;
}
if (frameSize.width > screenSize.width) {
frameSize.width = screenSize.width;
}
frame.setLocation((screenSize.width - frameSize.width) / 2,
(screenSize.height - frameSize.height) / 2);
frame.setVisible(true);
}

public static void main(String[] args) {
new TestPlayer();
}
}

追问
