Last Updated :

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:
Java
import java.util.*;
import org.javatuples.Unit;
class GfG {
public static void main(String[] args)
{
Unit<String> unit = Unit.with("GeeksforGeeks");
Unit<String> unit1 = Unit.with("GeeksNotforGeeks");
boolean res = unit.equals(unit1);
System.out.println("Is " + unit + " equal to "
+ unit1 + " : " + res);
}
}
|
Output:
Is [GeeksforGeeks] equal to [GeeksNotforGeeks] : false
Program 2: Using equals() with Quartet class:
Java
import java.util.*;
import org.javatuples.Quartet;
class GfG {
public static void main(String[] args)
{
List<String> list = new ArrayList<String>();
list.add("GeeksforGeeks");
list.add("A computer portal");
list.add("for geeks");
list.add("by Sandeep Jain");
Quartet<String, String, String, String> quartet
= Quartet.fromCollection(list);
String[] arr = { "GeeksforGeeks",
"A computer portal",
"for geeks",
"by Sandeep Jain" };
Quartet<String, String, String, String> otherQuartet
= Quartet.fromArray(arr);
boolean res = quartet.equals(otherQuartet);
System.out.println("Is \n" + quartet + "\n equal to \n"
+ otherQuartet + "\n : " + res);
}
}
|
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.
