比较分钟前的小时数:
int time1 = 350;
int time2 = 1210;
//
int hour1 = time1 / 100;
int hour2 = time2 / 100;
int comparationResult = Integer.compare(hour1, hour2);
if (comparationResult == 0) {
int min1 = time1 % 100;
int min2 = time2 % 100;
comparationResult = Integer.compare(min1, min2);
}

Integer.compare(i1, i2)已添加到Java 1.7中,对于以前的版本,您可以使用Integer.valueOf(i1).compareTo(i2)或
int comparationResult;
if (i1 > i2) {
comparationResult = 1;
} else if (i1 == i2) {
comparationResult = 0;
} else {
comparationResult = -1;
}
