JavaTuples equal() method

The equals() method in org.javatuples is used to check whether a TupleClass is equal to the TupleClass given as parameter. This method can be used to any tuple class object of javatuples library. It returns a boolean value that is true or false based on the equivalence of that TupleClass with existing TupleClass. Method Declaration:

public final boolean equals(Object obj)

Syntax:

boolean result = TupleClassObject.equals(TupleClass2Object)

Parameters: This method takes TupleClass2Object as parameter where:

• TupleClassObject- represents the JavaTuple Class object used like Unit, Quintet, Decade, etc.
• TupleClass2Object- represents the parameter passed JavaTuple Class object used like Unit, Quintet, Decade, etc.

Return Value: This method returns true if the TupleClassObject is equal to the TupleClass2Object. Else it returns false Below programs illustrate the various ways to use equals() method: Program 1: Using equals() with Unit class: 

Output:

Is [GeeksforGeeks] equal to [GeeksNotforGeeks] : false

Program 2: Using equals() with Quartet class: 

Output:

Is 
[GeeksforGeeks, A computer portal, for geeks, by Sandeep Jain]
 equal to 
[GeeksforGeeks, A computer portal, for geeks, by Sandeep Jain]
 : true

Note: Similarly, it can be used with any other JavaTuple Class.
