Java.math.BigDecimal.hashCode() Method


Advertisements


Description

The java.math.BigDecimal.hashCode() returns the hash code for this BigDecimal. Two BigDecimal objects that are numerically equal but differ in scale (like 2.0 and 2.00) will generally not have the same hash code.

Declaration

Following is the declaration for java.math.BigDecimal.hashCode() method.

public int hashCode()

Overrides

hashCode in class Object.

Parameters

NA

Return Value

This method returns the hashCode Value of the BigDecimal Object.

Exception

NA

Example

The following example shows the usage of math.BigDecimal.hashCode() method.

package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

   public static void main(String[] args) {

      // create 3 BigDecimal objects
      BigDecimal bg1, bg2, bg3;

      // create 3 int objects
      int i1, i2, i3;
   
      bg1 = new BigDecimal("125");
      bg2 = new BigDecimal("125.50");
      bg3 = new BigDecimal("125.80");

      // assign the HashCode value of bg1, bg2, bg3 to i1, i2, i3
      // respectively
      i1 = bg1.hashCode();
      i2 = bg2.hashCode();
      i3 = bg3.hashCode();

      String str1 = "HashCode of " + bg1 + " is " + i1;
      String str2 = "HashCode of " + bg2 + " is " + i2;
      String str3 = "HashCode of " + bg3 + " is " + i3;

      // print i1, i2, i3 values
      System.out.println( str1 );
      System.out.println( str2 );
      System.out.println( str3 );
   }
}

Let us compile and run the above program, this will produce the following result −

HashCode of 125 is 3875
HashCode of 125.50 is 389052
HashCode of 125.80 is 389982
