Charset equals() method in Java with Examples

The equals() method is a built-in method of the java.nio.charset checks if a given object of charset is equal to another given object of the charset. Two charsets are considered equal if, and only if, they have the same canonical names. A charset is never equal to any other type of object. 

Syntax:  

public final boolean equals(Object other)

Parameters: The function accepts a single mandatory parameter other which specifies the reference object with which it is compared with. 

Return Value: The function returns a boolean value. It returns true if it is equal, else it returns false. 

Below is the implementation of the above function:

Program 1: 

Java

// Java program to demonstrate
// the above function

import java.nio.charset.Charset;
import java.util.Iterator;
import java.util.Map;

public class GFG {

    public static void main(String[] args)
    {
        // First charset
        Charset first = Charset.forName("ISO-2022-CN");

        // Second charset
        Charset second = Charset.forName("UTF-8");

        System.out.println(first.equals(second));
    }
}

Output:

false

Program 2: 

Java

// Java program to demonstrate
// the above function

import java.nio.charset.Charset;
import java.util.Iterator;
import java.util.Map;

public class GFG {

    public static void main(String[] args)
    {

        // First charset
        Charset first = Charset.forName("UTF-8");

        // Second charset
        Charset second = Charset.forName("UTF-8");

        System.out.println(first.equals(second));
    }
}

Output:

true
