Question

如何用java在两个不同的时间之间求和。例如，我有这个：

 t1 = 10:03:45
t2 = 03:00
t3 = 01:12

==> Sum= 10:07:57

这是我的代码文章;

    SimpleDateFormat formatter = new SimpleDateFormat("mm:ss"); 
    SimpleDateFormat formatter2 = new SimpleDateFormat("HH:mm:ss"); 

    Time t1 = new Time(formatter.parse("10:03:45").getTime());
    Time t2 = new Time(formatter.parse("03:00").getTime());
    Time t3 = new Time(formatter.parse("01:12").getTime());


    Long sum= formatter2.parse(t1.toString()).getTime() +(formatter.parse(t2.toString()).getTime() + formatter.parse(t3.toString()).getTime());

    System.out.println("***** gettime t1 "+formatter2.parse(t1.toString()).getTime()); // -2997000
    System.out.println("******* gettime t2 "+formatter.parse(t2.toString()).getTime()); // -3597000
    System.out.println("******* gettime t3 "+formatter.parse(t3.toString()).getTime());  // -3599000

    System.out.println("-----------Sum with time "+formatter2.format(total)); // 22:10:07
    System.out.println("-----------Sum "+sum); //-10193000

我不明白为什么它显示时间的否定，而且总数不正确。

感谢您帮助我找到“时代”的确切总数，

两次之间如何相加？
