Question

我收到异常java.lang.UnsupportedOperationException：不支持

代码是

 private static void mode(int i) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    private static void quality(int i) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    private static void complexity(int i) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    private static void sampleRate(int i) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
public static void main(final String[] args)
     {
      mode(0);
      quality(1);
      complexity(1);
      sampleRate(8000);
    JSpeexEnc encoder = new JSpeexEnc();
    if (encoder.parseArgs(args, FILE_FORMAT_WAVE)) {
      encoder.encode();

    }

请告诉我为什么这个例外即将来临......

Answer 1

您正在调用throws UnsupportedOperationException.

的方法

private static void mode(int i) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

private static void quality(int i) {
    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}

private static void complexity(int i) {
    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}

private static void sampleRate(int i) {
    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}

替换为

private static void mode(int i) {
         //what you want to do
    }

    private static void quality(int i) {
        //what you want to do
    }

    private static void complexity(int i) {
        //what you want to do
    }

    private static void sampleRate(int i) {
         //what you want to do
    }

Answer 2

该行：

throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.

是异常的原因。这意味着，无论何时调用此方法，它都会抛出异常，就像您定义它一样！

Answer 3

您还可以在main方法中处理异常，以避免程序抛出异常。像这样的东西 - ：

private static void mode（int i）{ 抛出新的UnsupportedOperationException（“尚不支持。”）; //要更改生成方法的主体，请选择“工具”|模板。 }

    private static void quality(int i) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    private static void complexity(int i) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    private static void sampleRate(int i) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
public static void main(final String[] args)
     {
    try
    {
      mode(0);
      quality(1);
      complexity(1);
    }catch(Exception ex)
    {
        System.out.println(ex.getMessage());
    }


     }

java中不支持的操作异常
