Character.hashCode() in Java with examples

Java.lang.Character.hashCode() is a built-in method in Java which returns a hash code for this Character. The returned hash code is equal to the result of invoking charValue().

Syntax:

public int hashCode()

This function does not accepts any parameter.

Return Value: This method returns a hash code value for this Character.

Below programs illustrate the Java.lang.Character.hashCode() function:

Program 1:

// Java program to demonstrate the
// function when the value passed in the parameter
// is a character
import java.lang.*;

public class Gfg {

    public static void main(String[] args)
    {
        // parameter ch
        char ch = 'B';
        // assigns character values
        Character c = Character.valueOf(ch);


        // assign hashcodes of c1, c2 to i1, i2
        int i = c.hashCode();

        // prints the character values
        System.out.println("Hashcode of " + ch + " is " + i);
    }
}

Output:

Hashcode of B is 66

Program 2:

// Java program to demonstrate the
// function when the value passed in the parameter
// is a number
import java.lang.*;

public class Gfg {

    public static void main(String[] args)
    {
        // parameter ch
        char ch = '6';
        // assigns character values
        Character c = Character.valueOf(ch);


        // assign hashcodes of ch
        int i = c.hashCode();

        // prints the character values
        System.out.println("Hashcode of " + ch + " is " + i);
    }
}

Output:

Hashcode of 6 is 54
