主要代码如下
1 public class test {
2
3 public static void main(String[] args) {
4 long ms = 300000
;
5 SimpleDateFormat formatter =
new SimpleDateFormat("HH:mm:ss"
);//这里想要只保留分秒可以写成"mm:ss"
6 formatter.setTimeZone(TimeZone.getTimeZone("GMT+00:00"
));
7 String hms =
formatter.format(ms);
8 System.out.println(hms);
9 }
10
11 }
