Need some help with project - help is VERY appreciated!

Question

This one has been driving me nuts for a few days. So basically, I have this constructor.
public SportStacker( String newName, int numTimes, int newID )
         name = newName;
         numTimesRecorded = 0;
         times = new double[ numTimes ];
         ID = newID;
      }The important thing here being that it sets ID = newID. That's in the SportStacker class. We also have a method in SportStacker named getID:
public int getID()
         return ID;
      }Okay, then we have another class, Contestant. In this class, we have an array of SportStacker objects. One method we had to create was to add a new contestant.
public void addCompetitor(String name, int numTimesRecorded)
         if(numCompetitors == competitors.length)
            increaseSize();
         SportStacker temp = new SportStacker(name, numTimesRecorded, IDtracker);
         competitors[numTimesRecorded] = temp;
         numCompetitors++;
         IDtracker++;
}Which I think is fine. However, the next one is addCompetitorTimes. It seems like it should be easy, but this part confuses me...in his instructions, he says: "This method should take in two parameters: an int representing the competitors ID and a double representing the time to be recorded. Then, search through competitors for the correct ID using the getID method provided in SportStacker..." This is what confuses me. One of the parameters taken in this method is the int representing his ID, and all getID will do is return what was last used in the constructor. It doesn't make any sense to me! Someone please help!

Minus the addTime part, just wanted to make sure I was doing this right first. Thanks so much for the help, your explanation helped me understand a lot!Using a for loop is clearer but yes your on the right track. Minor note, if the competitors array contains nulls then a runtime error will occur due to .getID() applied to a null object. This is easily avoidable.
public void addCompetitorTimes(int compID, double timeToRecord){
  for(int i=0; i<numCompetitors; i++){
    if(competitors.getID() == compID){
System.out.print("Add time stuff here...");
break; //Break from for loop, no need to check other IDs
