Help with maze time result code...

[Phillip Browne]

Hey guys,

Just asking for a little help here. I am trying to finish a java program for a class and I am stuck on a bit of code. I've figured out most of the code but am stuck on the code at the end:

 
/**
     * Gets the maze time for the rodent.
     * 
     * @return String The formatted maze time for the rodent.
     */
    public String getMazeTime()
    {
 

 
    }   
    
    /**
     * Gets a formatted string with information for the rodent and maze.
     * 
     * @return String String with information for rodent and maze.
     */
    public String toString()
    {
 

 
    }   
}
 

Here is the code in it's entirety:

 

/**
 * Provides maze results for a rodent.
 * 
 * @author Ray Waite
 * @version December 2006
 */
public class MazeResult
{
    // instance variables
    private Rat rodent;
    private Time startTime;
    private Time endTime;
 

    /**
     * Constructor for objects of class MazeResult.
     */
    public MazeResult(Rat inRat)
    {
        myRat = inRat;
    }
 
    /**
     * Sets the rodent.
     * 
     * @param inRat Rat object.
     */
    public void setRat(Rat inRat)
    {
 
        This.setRat = new Rat ();
 
    }
    
    /**
     * Gets the rodent.
     * 
     * @return Rat The Rat object.
     */
    public Rat getRat()
    {
return myRat;
    }
    
    /**
     * Sets the start time for the rodent.
     * 
     * @param inHour Hour of the rodent's start time.
     * @param inMinutes Minutes of the rodent's start time.
     * @param inSeconds Seconds of the rodent's start time.
     */
    public void setStartTime(int inHour, int inMinutes, int inSeconds)
    {
        this.startTime = new Time(inHour, inMinutes, inSeconds);
    }
    
    /**
     * Gets the start time for the rodent.
     * 
     * @return Time The start time of the rodent.
     */
    public Time getStartTime()
    {
        if (this.startTime == null)
        {
            return null;
        }
        Time tempStartTime = new Time(this.startTime.getHour(),
            this.startTime.getMinutes(), this.startTime.getSeconds());
        return tempStartTime;
    }
    
    /**
     * Sets the end time for the rodent.
     * 
     * @param inHour Hour of the rodent's end time.
     * @param inMinutes Minutes of the rodent's end time.
     * @param inSeconds Seconds of the rodent's end time.
     */
    public void setEndTime(int inHour, int inMinutes, int inSeconds)
    {
        this.endTime = new Time(inHour, inMinutes, inSeconds);
    }
    
 
 
    /**
     * Gets the end time for the rodent.
     * 
     * @return Time The end time of the rodent.
     */
    public Time getEndTime()
    {
        if (this.endTime == null)
        {
            return null;
        }
        Time tempEndTime = new Time(this.endTime.getHour(),
            this.endTime.getMinutes(), this.endTime.getSeconds());
        return tempEndTime;
    }
    
    /**
     * Gets the maze time for the rodent.
     * 
     * @return String The formatted maze time for the rodent.
     */
    public String getMazeTime()
    {
 

 
    }   
    
    /**
     * Gets a formatted string with information for the rodent and maze.
     * 
     * @return String String with information for rodent and maze.
     */
    public String toString()
    {
 

 
    }   
}
 

I would very much "love" some help.  Thanks.

Welcome to JavaRanch!

Have you compiled this code yet? Don't wait until it's "done" to compile. You should recompile each time you add something, so you don't end up with errors that build on each other.

Also, if "Time" is java.sql.Time, you should check the API. Most of the methods are deprecated. The non-deprecated methods are inherited from java.util.Date, so you might want to consider using Date instead. Better yet, use java.util.Calendar.

Agree with Marc Weber. Also your method which has a return null in looks very peculiar; I think it might not work correctly. Beware of returning null anywhere; it can produce unexpected exceptions or errors later.

[Bob Good]

Well you have these members in the maze result:

private Rat rodent;
private Time startTime;
private Time endTime;

Perhaps your toString() would do something like:

return getRodent().toString() + "; start: " + getStartTime() + "; end: " + getEndTime();

Rat class should have a toString method too.
