I checked all answers mentions in this post, didn't able to get a correct and formatted output from any. finally found the answer im looking for in this post,http://memorynotfound.com/calculate-relative-time-time-ago-java/
import java.util.Date;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.concurrent.TimeUnit;
public class TimeAgo {
public static final Map<String, Long> times = new LinkedHashMap<>();
static {
times.put("year", TimeUnit.DAYS.toMillis(365));
times.put("month", TimeUnit.DAYS.toMillis(30));
times.put("week", TimeUnit.DAYS.toMillis(7));
times.put("day", TimeUnit.DAYS.toMillis(1));
times.put("hour", TimeUnit.HOURS.toMillis(1));
times.put("minute", TimeUnit.MINUTES.toMillis(1));
times.put("second", TimeUnit.SECONDS.toMillis(1));
}
public static String toRelative(long duration, int maxLevel) {
StringBuilder res = new StringBuilder();
int level = 0;
for (Map.Entry<String, Long> time : times.entrySet()){
long timeDelta = duration / time.getValue();
if (timeDelta > 0){
res.append(timeDelta)
.append(" ")
.append(time.getKey())
.append(timeDelta > 1 ? "s" : "")
.append(", ");
duration -= time.getValue() * timeDelta;
level++;
}
if (level == maxLevel){
break;
}
}
if ("".equals(res.toString())) {
return "0 seconds ago";
} else {
res.setLength(res.length() - 2);
res.append(" ago");
return res.toString();
}
}
public static String toRelative(long duration) {
return toRelative(duration, times.size());
}
public static String toRelative(Date start, Date end){
assert start.after(end);
return toRelative(end.getTime() - start.getTime());
}
public static String toRelative(Date start, Date end, int level){
assert start.after(end);
return toRelative(end.getTime() - start.getTime(), level);
}
}
