Java程序将毫秒转换为可读字符串
假设以下是毫秒的声明：
long millis = 5000000;
现在从毫秒获取小时，分钟和秒：
long hours = TimeUnit.MILLISECONDS.toHours(millis); long minutes = TimeUnit.MILLISECONDS.toMinutes(millis) - (hours * 60); long seconds = TimeUnit.MILLISECONDS.toSeconds(millis) - ((hours * 60 * 60) + (minutes * 60));
使用String.format()将上面的内容转换为可读的字符串。
示例
import java.util.concurrent.TimeUnit;
public class Demo {
public static void main(String[] argv){
long millis = 5000000;
long hours = TimeUnit.MILLISECONDS.toHours(millis);
long minutes = TimeUnit.MILLISECONDS.toMinutes(millis) - (hours * 60);
long seconds = TimeUnit.MILLISECONDS.toSeconds(millis) - ((hours * 60 * 60) + (minutes * 60));
millis = millis - ((hours * 60 * 60 * 1000) + (minutes * 60 * 1000) + (seconds * 1000));
System.out.println(String.format("Hours = %d\nMinutes = %d\nSeconds = %d\nMilliseconds =
%d", hours, minutes, seconds, millis));
System.out.println(String.format("%d hr(s) %d min(s) %d sec(s) %d ms", hours, minutes, seconds, millis));
}
}输出结果
Hours = 1 Minutes = 23 Seconds = 20 Milliseconds = 0 1 hr(s) 23 min(s) 20 sec(s) 0 ms
