JAVA 把秒转作 时:分:秒

如题
long a = 100; <--- 100秒
我想把它转做
00:01:40
要如何做??? 谢谢~!!
一楼的很好, 但是想会分别出100秒->00:01:40, 5秒 -> 00:00:50, 要如何???

Answer 1

public class Test{
public static void main(String[] args){
long a=100；
long hour=a/3600; !小时
long minute=a%3600/60; !分钟
long second=a%60; !秒
System.out.println(hour+":"+minute+":"+second);
}
}

Answer 2

5秒 -> 00:00:50 ？？楼主想说的应该是5秒 -> 00:00:05吧
很简单
把一楼的兄弟的程序稍稍改下
public class Test{
public static void main(String[] args){
long a=100；
long hour=a/3600; !小时
long minute=a%3600/60; !分钟
long second=a%60; !秒
String b = "" ;
String c = "" ;
String d = "" ;
if(second< 10){
b = "0";
}

if(minute< 10){
c = "0";
}
if(hour< 10){
d = "0";
}

System.out.println(d+hour + ":" +c+minute + ":" + b+second);
}
}

Answer 3

public class ZhiDaoTest {
public static void main(String[] args){
int a = 100;
System.out.println(getTime(a));

}

public static String getTime(int a){
int h = 0;
int m = 0;
int s = 0;
String hh = "";
String mm = "";
String ss = "";
h=a/3600;
m=(a-h*3600)/60;
s=a-(h*3600)-(m*60);
if(h<10){
hh = "0"+h;
}else{
hh = h+"";
}
if(m<10){
mm = "0"+m;
}else{
mm = m+"";
}
if(s<10){
ss = "0"+s;
}else{
ss = s+"";
}
return hh+":"+mm+":"+ss;
}
}

Answer 4

String toStringTime(long l){
long h=l/3600;
long m=l/60%60;
long s=l%60;
String fs = String.format("%02d:%02d:%02d",h,m,s);
return fs;
}
