Java N-Tuple implementation

Question

I just made a Java n-tuple which is type-safe.
I\'m using some unconventional methods to achieve type-safety (I just made it for fun).

Can someone can give some

Answer 1

saw this code in wave project

public class Tuple {

  private final A[] elements;

  public static  Tuple of(A ... elements) {
    return new Tuple(elements);
  }

  public Tuple(A ... elements) {
    this.elements = elements;
  }

  public A get(int index) {
    return elements[index];
  }

  public int size() {
    return elements.length;
  }

  public boolean equals(Object o) {
    if (this == o) {
      return true;
    }

    if (o == null || o.getClass() != this.getClass()) {
      return false;
    }

    Tuple o2 = (Tuple) o;
    return Arrays.equals(elements, o2.elements);
  }

  @Override
  public int hashCode() {
    return Arrays.hashCode(elements);
  }

  @Override
  public String toString() {
    return Arrays.toString(elements);
  }
}
