MathContext Class hashCode() method

  • hashCode() method is available in java.math package.
  • hashCode() method is used to get the hash code value of this MathContext.
  • 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 does not throw an exception at the time of returning hash code.

Syntax:

    public int hashCode();

Parameter(s):

  • None

Return value:

The return type of this method is int, it retrieves this MathContext hash code value.

Example:

// Java program to demonstrate the example 
// of int hashCode() method of MathContext

import java.math.*;

public class HashCodeOfMC {
    public static void main(String args[]) {
        // Initialize three MathContext objects  
        MathContext ma_co1 = new MathContext(3, RoundingMode.CEILING);
        MathContext ma_co2 = new MathContext(4);
        MathContext ma_co3 = new MathContext(6, RoundingMode.FLOOR);

        // returns the hash code of this MathContext
        // ma_co1 
        int hash_code = ma_co1.hashCode();
        System.out.println("ma_co1.hashCode(): " + hash_code);

        // returns the hash code of this MathContext
        // ma_co2 
        hash_code = ma_co2.hashCode();
        System.out.println("ma_co2.hashCode(): " + hash_code);

        // returns the hash code of this MathContext
        // ma_co3 
        hash_code = ma_co3.hashCode();
        System.out.println("ma_co3.hashCode(): " + hash_code);
    }
}

Output

ma_co1.hashCode(): 1420167577
ma_co2.hashCode(): 931231881
ma_co3.hashCode(): -18805464
