java 数值类型分秒时间格式化的实例代码

java 实例代码：

import java.util.concurrent.TimeUnit;public class DateUtils {  private static final String[] UNIT_DESC = new String[]{"天", "小时", "分钟", "秒"};    public static String convertMinute2Str(long minute) {    StringBuilder sb = new StringBuilder();    long[] date = {TimeUnit.SECONDS.toHours(minute) % 24,TimeUnit.SECONDS.toMinutes(minute) % 60, TimeUnit.SECONDS.toSeconds(minute) % 60};    for (int i = 0; i < date.length; i++) {      long l = date[i];      if (l > 0) sb.append(l).append(UNIT_DESC[i]);    }    return sb.toString();  }      public static String convertSeconds2Str(long seconds) {    StringBuilder sb = new StringBuilder();    long[] date = {TimeUnit.SECONDS.toDays(seconds), TimeUnit.SECONDS.toHours(seconds) % 24, TimeUnit.SECONDS.toMinutes(seconds) % 60, TimeUnit.SECONDS.toSeconds(seconds) % 60};    for (int i = 0; i < date.length; i++) {      long l = date[i];      if (l > 0) sb.append(l).append(UNIT_DESC[i]);    }    return sb.toString();  }    public static void main(String[] args) {System.out.println(convertMinute2Str(140));   // 2小时20分钟System.out.println(convertSeconds2Str(33680)); // 9小时21分钟20秒}}
