BigDecimal Class hashCode() method

• hashCode() method is available in java.math package.
• hashCode() method is used to get the hash code value for this BigDecimal object.
• 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 value.

Syntax:

    public int hashCode();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of this method is int, it returns this BigDecimal hash code value.

Example:

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

import java.math.*;

public class HashCodeOfBD {
    public static void main(String args[]) {
        // Initialize two variables first is
        // of "int" and second is of "String"
        // type
        int val = 115;
        String str = "100";

        // Initialize two BigDecimal objects  
        BigDecimal b_dec1 = new BigDecimal(val);
        BigDecimal b_dec2 = new BigDecimal(str);

        // returns the hash code value of this 
        // BigDecimal b_dec1
        int hash_code = b_dec1.hashCode();
        System.out.println("b_dec1.hashCode(): " + hash_code);

        // returns the hash code value of this 
        // BigDecimal b_dec2
        hash_code = b_dec2.hashCode();
        System.out.println("b_dec2.hashCode(): " + hash_code);
    }
}

Output

b_dec1.hashCode(): 3565
b_dec2.hashCode(): 3100
