    public void setSGGoldCoin(int sgGoldCoin) {
        sgGoldCoin = sgGoldCoin;
    }

    public void setSGGoldCoin(int sgGoldCoin) {
        this.sgGoldCoin = sgGoldCoin;
    }

今天算长见识了，因为手快（复制|粘贴），写了出了第一段代码，造成的结果是，修改无效，晕死，浪费了好多时间。

捕捉线程里面的异常。（如果是单个线程，设置UncaughtExceptionHandler属性）

Thread thread = new Thread(new Task());  
thread.setUncaughtExceptionHandler(new ExceptionHandler());  
thread.start(); 

 全局设置线程异常监听

Thread.setDefaultUncaughtExceptionHandler(new ExceptionHandler());
