JAVA中抓异常的办法

　　前几天有人说软件出错了，又不知道哪里出错。然后吾就想自己抓异常。

　　昨天终于闲了下来，于是就重操旧业。

public class UnExceptionHandler implements Thread.UncaughtExceptionHandler
{

private static UnExceptionHandler exceptionHandler;
private static long lastTime;
private static long File logFile;

public static UnCatchHandler getInstance()
{
    if(mUnCatchHandler == null)
    {
        synchronized (UnCatchHandler.class)
        {
            exceptionHandler = new UnExceptionHandler();
            Thread.setDefaultUncaughtExceptionHandler(exceptionHandler);
            lastTime = System.current();
            logFile = new File();
        }
    }
    return exceptionHandler;
}

private UnCatchHandler(Context context)
{
    //
}


/**
 * 保存异常
 * @param t
 * @param e
 */
@Override
public void uncaughtException(Thread t, Throwable e)
{
    //时间控制，文件大小控制
    try
    {
        BufferedWriter writer = new BufferedWriter(new FileWriter(logFile));
        witer.write(time);
        for (ele : e.get())
        {
             writer.write();
        }
        writer.close();
    }
    catch (Exception ex)
    {
        ex.printStackTrace();
    }
}
