Java: convert seconds into day, hour, minute and seconds using TimeUnit

Question

I am using TimeStamp class to convert seconds into Day,Hours,Minutes,Seconds. I used following code

public static void calculateTime(long seconds) {
                 


        

Answer 1

Simple method:

public static void calculateTime(long seconds) {
    long sec = seconds % 60;
    long minutes = seconds % 3600 / 60;
    long hours = seconds % 86400 / 3600;
    long days = seconds / 86400;

    System.out.println("Day " + days + " Hour " + hours + " Minute " + minutes + " Seconds " + sec);
}

Answer 2

Here is a code i created : (For 3600 seconds it shows "Days:0 Hours:1 Minutes:0 Seconds:0")

public class TimeConvert 
{
    public static void main(String[] args) 
    {
        int fsec,d,h,m,s,temp=0,i;
        fsec=3600;
        //For Days
        if(fsec>=86400)
        {
            temp=fsec/86400;
            d=temp;
            for(i=1;i<=temp;i++)
            {
                fsec-=86400;
            }
        }
        else
        {
            d=0;
        }
        //For Hours
        if(fsec>=3600)
        {
            temp=fsec/3600;
            h=temp;
            for(i=1;i<=temp;i++)
            {
                fsec-=3600;
            }            
        }
        else
        {
            h=0;
        }
        //For Minutes
        if(fsec>=60)
        {
            temp=fsec/60;
            m=temp;
            for(i=1;i<=temp;i++)
            {
                fsec-=60;
            }            
        }
        else
        {
            m=0;
        }
        //For Seconds
        if(fsec>=1)
        {
            s=fsec;            
        }
        else
        {
            s=0;
        }
        System.out.println("Days:"+d+" Hours:"+h+" Minutes:"+m+" Seconds:"+s);
    }
}

Hope it answers your question.
