Date time1 = new Date();
        Date time2 = new Date();
        int min1 = time1.getMinutes();
        int min2 = time2.getMinutes();
        int sec1 = time1.getSeconds();
        int sec2 = time2.getSeconds();

------解决方案--------------------

java.sql.Time d1  = new java.sql.Time(10, 10, 10);
java.sql.Time d2  = new java.sql.Time(11, 9, 45);
int i = d1.compareTo(d2);

构造函数中分别是时分秒。
i > 0 说明d1大
i=0说明　d1==d2
