Character class hashCode() method

hashCode() method is available in java.lang package.

hashCode() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
hashCode() method is a final method it does not override in child class.
hashCode() method does not throw an exception at the time of returning hash code.

Syntax

public final int hashCode();

Parameters

It does not accept any parameter.

Return Value

The return type of this method is int, it returns hash code for this Subset object.

Example

// Java program to demonstrate the example 
// of int hashCode() method of Character.Subset

public class HashcodeOfCharacterSubset extends Character.Subset {
    HashcodeOfCharacterSubset(String str) {
        super(str);
    }

    public static void main(String[] args) {
        String str1 = new String("Java");
        HashcodeOfCharacterSubset value1 = new HashcodeOfCharacterSubset(str1);

        String str2 = new String("Programming");
        HashcodeOfCharacterSubset value2 = new HashcodeOfCharacterSubset(str2);

        int hashcode1 = value1.hashCode();
        System.out.println("value1.hashCode(): " + hashcode1);

        int hashcode2 = value2.hashCode();
        System.out.println("value2.hashCode(): " + hashcode2);
    }
}

Output

value1.hashCode(): 1785210046
value2.hashCode(): 1151020327
