I need help making a program. It deals with BaseTime.

Question

Hey. Look im having a lot of trouble with a program. It is actually a program i have to make based on another program that i was given. it is called BaseTimeTest. here is the code of that program:
import java.io.PrintStream;
public class BaseTimeTest
     public static void main(String[]args)
          PrintStream out = System.out;
          BaseTime t0 = new BaseTime();
          out.println(t0);
          BaseTime t1 = new BaseTime(13,25,46);
          out.println(t1);
          BaseTime t2 = new BaseTime(6,0);
          out.println(t2);
          try
               BaseTime tbad = new BaseTime(23,59,60);
               out.println(tbad);
          catch(IllegalArgumentException e)
               System.err.println(e.getMessage());
          long ctime = System.currentTimeMillis();
          ctime /= 1000;
          ctime %= BaseTime.SECONDS_PER_DAY;
          out.println(ctime);
          BaseTime t3 = new BaseTime((int)ctime);
          outprintln(t3);
          int h=t3.getHours()-5;
          if(h<0)h+=24;
               out.println(h+":"+t3.getMinutes()+":"+t3.getSeconds());
          out.println(t3.getSecondsSinceMidnight());
          t3.setHours(12);
          t3.setMinutes(0);
          t3.setSeconds(0);
          out.println(t3);
          t2=new BaseTime(13,25,46);
          if(t1.equals(t2))
               out.println(t1+"=="+t2);
          else
               out.println(t1+"!="+t2);
          t2.setMinutes(37);
          out.println(t1+"?"+t2+"=>"+t1.compareTo(t2));
          out.println(t1+"diff"+t2+"=>"+t1.diff(t2));
          t1=new BaseTime(3,14,25);
          t2=new BaseTime(5,48,45);
          out.println(t1+"plus"+t2+"=>"+t1.plus(t2));
          out.println(t1+" + "+t2+"=>");
          t1.add(t2);
          out.println(t1);
What i have to do is create the class which this program uses to run called BaseTime. I know that the java system already has a class named baseTime() but i have to make my own. I need to make get and set methods but i am asking all of you if you can give me some ideas and maybe even code samples. The help would be greatly appreicated. i'll reply to what you say but it maynot be right away as i am very busy.

Answer 1

I need a setHours method, a setMinutes method, a
setSeconds method, a getHours method, a getMinutes
method, a getSeconds method, java.util.Calendar effectively has all these.
a setSecondsSinceMidnight method, and a getSecondsSinceMidnight method. Not hard to come up with.
I also need multiple BaseTime methods because i need to have
overloaded methods because each method has to take in
different arguments. One takes in no arguments, one
takes in one argument, one takes in two arguments and
one takes in three arguments. And what are these methods doing?
I also need methods that convert milliseconds to seconds, one that
converts minutes to seconds and one that converts
hours to seconds. This is all pretty simple. I would extend GregorianCalendar or wrap a GregorianCalendar. Most of what you need is already there, and all you need to do is add the few other methods.
getSecondsSinceMidnight - make a calendar representing midnight, get the milliseconds value for both, subtract, convert to seconds.
setSecondsSinceMidnight - I would try setLenient(false), set the calendar to midnight, and then just set the seconds field. Might work.
Conversion - simple arithmetic.
Other methods - you didn't mention what they do.
