SortedSet equals() method in Java with Examples

The equals() method of java.util.SortedSet class is used to verify the equality of an Object with a SortedSet and compare them. The method returns true if the size of both the SortedSets are equal and both contain the same elements.

Syntax:  

public boolean equals(Object o)

Parameters: This method takes the object o as a parameter to be compared for equality with this set.

Returns Value: This method returns true if the specified object is equal to this set.

Note: The equals() method in SortedSet is inherited from the Set interface in Java.

Below are the examples to illustrate the equals() method.

Example 1: 

Java




// Java program to demonstrate equals()
// method of SortedSet
 
import java.util.*;
 
public class GFG {
    public static void main(String[] argv)
    {
 
        // Creating object of Set
        SortedSet<String> arrset1
            = new TreeSet<String>();
 
        // Populating arrset1
        arrset1.add("A");
        arrset1.add("B");
        arrset1.add("C");
        arrset1.add("D");
        arrset1.add("E");
 
        // print arrset1
        System.out.println("First Set: "
                           + arrset1);
 
        // Creating another object of Set
        SortedSet<String> arrset2
            = new TreeSet<String>();
 
        // Populating arrset2
        arrset2.add("A");
        arrset2.add("B");
        arrset2.add("C");
        arrset2.add("D");
        arrset2.add("E");
 
        // print arrset2
        System.out.println("Second Set: "
                           + arrset2);
 
        // comparing first Set to another
        // using equals() method
        boolean value
            = arrset1.equals(arrset2);
 
        // print the value
        System.out.println("Are both set equal? "
                           + value);
    }
}


Output: 

First Set: [A, B, C, D, E]
Second Set: [A, B, C, D, E]
Are both set equal? true

 

Example 2: 

Java




// Java program to demonstrate
// equals() method of Sorted Set
 
import java.util.*;
 
public class GFG1 {
    public static void main(String[] argv)
    {
 
        // Creating object of Set
        SortedSet<Integer> arrset1
            = new TreeSet<Integer>();
 
        // Populating arrset1
        arrset1.add(10);
        arrset1.add(20);
        arrset1.add(30);
        arrset1.add(40);
        arrset1.add(50);
 
        // print arrset1
        System.out.println("First Set: "
                           + arrset1);
 
        // Creating another object of Set
        SortedSet<Integer> arrset2
            = new TreeSet<Integer>();
 
        // Populating arrset2
        arrset2.add(10);
        arrset2.add(20);
        arrset2.add(30);
 
        // print arrset2
        System.out.println("Second Set: "
                           + arrset2);
 
        // comparing first Set to another
        // using equals() method
        boolean value
            = arrset1.equals(arrset2);
 
        // print the value
        System.out.println("Are both set equal? "
                           + value);
    }
}


Output:

First Set: [10, 20, 30, 40, 50]
Second Set: [10, 20, 30]
Are both set equal? false
