Question

我使用netbeans，我有这个代码通过我播放音频剪辑

现在，我希望当用户按下JFrame上的下一个按钮时。框架配置另一个打开，剪辑停止。

这是我的代码：

这是按钮的mose发布事件：

Reg1 ro = new Reg1();
ro.setVisible(true);
clip.close();
this.dispose();

这主要是：

java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                Welcome1 insta = new Welcome1();
                insta.setVisible(true);
                        KeyListener s;

        try {
            AudioInputStream audio = AudioSystem.getAudioInputStream(new File("x.wav"));
            Clip clip = AudioSystem.getClip();
            clip.open(audio);
            clip.start();
        }

        catch(UnsupportedAudioFileException uae) {
            System.out.println(uae);
        }
        catch(IOException ioe) {
            System.out.println(ioe);
        }
        catch(LineUnavailableException lua) {
            System.out.println(lua);
        }

            }
        });

它在行clip.close（）;

中显示错误

我应该采取什么措施来消除错误？因为我是新手，请解释你的答案。

错误是：

Answer 1

我猜在代码调用Clip时Clip.close()实例超出了范围。

这只是猜测，因为很难用代码片段说出来，堆栈跟踪的行号无法指示确切的代码行。请考虑将来发布SSCCE。

Answer 2

我需要做的是初始化类下的变量，而不是在main下...就像那样简单
