Last Updated : 28 Mar, 2019

The hashCode() method is a built-in method of the java.nio.charset returns the computed hashcode of any given charset. Syntax:

public final int hashCode()

Parameters: The function does not accepts any parameter. Return Value: The function returns the computed hashcode for the charset. 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)
    {

        // Gets the charset
        Charset first = Charset.forName("ISO-2022-CN");

        // Prints the hash-code
        System.out.println("The hash code for ISO-2022-CN is " + first.hashCode());
    }
}

Output:

The hash code for ISO-2022-CN is 1450311218

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)
    {

        // Gets the charset
        Charset first = Charset.forName("x-windows-949");

        // Prints the hash-code
        System.out.println("The hash code for x-windows-949 is " + first.hashCode());
    }
}

Output:

The hash code for x-windows-949 is -1698752417
