How Can Tuples Be Implemented in Java for Hashtable Value Structures?

Utilizing Pairs or 2-tuples in Java

Enhancing a Java Hashtable with value structures that incorporate a tuple configuration has prompted the question of which data structure can effectively serve this purpose. The absence of an inherent tuple class in Java necessitates alternative approaches.

One viable solution involves the creation of a custom tuple class, such as the following:

public class Tuple<X, Y> { 
  public final X x; 
  public final Y y; 
  public Tuple(X x, Y y) { 
    this.x = x; 
    this.y = y; 
  } 
} 

Considerations:

Implementing a custom tuple class requires careful attention to factors such as equality, immutability, and potential usage as hashing keys. These aspects warrant further exploration to ensure the class operates as intended within the desired context.
