javaarraysoopgetter

Is there a way to avoid manually writing each of this getter functions?

I have a series of String[] arrays which are list of words. Something like:

String[] ListOne = new String[100];
String[] ListTwo = new String[100];
/*And so on with other lists */

ListOne[0] = "word00";
ListOne[1] = "word01";
/*And so on till*/
ListLast[99] = "word 99 from last list";

Now, I want a function for each list that, given a number returns the corresponding element (word):

public String GetFromListOne(int key) { return ListOne[key];}

Is there a way to avoid manually writing each of this getter functions?

In PHP, for example, I would just use the magic method __call,
or pass as an argument with the list name and reference it dynamically.

Is there a way to do something similar in Java?
Or an alternative strategy to achieve the same result?

Solution

  • You should look into inheritance.

    What you basically must do is define an interface (or extend a List class) 

     public interface ListTest{
//**Gets keys from lists*//
GetFromListOne(int key);
}

    then 

    public class Listone implements ListTest{

/** methods **//
GetFromListOne(int key);
/** methods **//
}

    Have fun extending
