How do I create multiple Java object instances from an array?

Question

I'm trying to get this method to create two instances of the class 'Sport'. The method is passing in a array which has the information about the class which is then sent to the constructor to be created.

However, I'm unsure how to refer to instance 1 or 2 given my code.

public static void seperateValues(String sportDetail) {
  String[] sportDetails = sportDetail.split(",");
  System.out.println("Adding new sport to the Sport collection");
  System.out.println(sportDetail);
  /*
  for(int i=0; i<sportDetails.length; i++) //just used for testing whether it was splitting correctly {
    System.out.println(sportDetails[i]); 
  }*/
  //name,usagefee,insurance,affiliationfees, then court numbers
  //Tennis,44,10,93,10,11,12,13,14,15,16
  int vlength;
  vlength = sportDetail.length();
  new Sport(sportDetails); //this static methods loops twice, giving tennis and baseball
  System.out.println(name); //this lists tennis and baseball respectively
 }

Answer 1

If you just want to refer to two instances of sport, you can simply do this:

Sport sport1 = new Sport(sportDetails);
Sport sport2 = new Sport(sportDetails);

And then simply call sport1 or sport2 when you want to access them, however if you want to use that method n number of times for n number of sports, you can do this: First change the separateValues() method to return a sport, by changing these lines:

public static void seperateValues(String sportDetail) {

to

public static Sport seperateValues(String sportDetail) {

At the end of the method, make it return a sport, like this:

Sport sport = new Sport(sportDetails);
return sport;

And then you can call the method inside a loop and create a list, so you can create as many sports are you need:

//First declare a list of sports:
List<Sport> sports = null;

for (int i = 0; i<asManySportsAsYouWantToAdd; i++){
sports.add(separateValues(sportDetail));
}

And then, to access each individual sport, you can simple use:

sports.get(n); //Where n is place of the sport on the list

Answer 2

Assuming your original string sportDetail was "tennis,baseball", which then turned into an array of 2 terms, such as sportDetails[0] = "tennis" and sportDetails[1] = "baseball" , then within your class Sport you simply need to reference them as such.

In other words, sportDetails[0] .
