Java how to: Generic Array creation

I wanna create something like this:

public class MyClass<T> {
    private int row;
    private int column;
    private T[][] result;

    public T[][] generation(int size, T[] values) {
        result = new T[values.length][size];

        generator(0, 0);

        return result;
    }
}

But I’m gettin an error “generic array creation”, how can I fix that? 🙁

Answer 1

If you can get the type of T i.e. Class<T>, you can utilize Array.newInstance as follows…

public T[][] generation(int size, T[] values) {
  result = (T[][]) Array.newInstance(values.getClass().getComponentType(),
      values.length, size);
  generator(0, 0);
  return result;
}
