BigDecimal equals() Method in Java

The java.math.BigDecimal.equals() method checks for equality of a BigDecimal value with the object passed. This method considers two BigDecimal objects equal if only if they are equal in value and scale. Syntax:

public boolean equals(Object obj)

Parameters: This function accepts an Object obj as a mandatory parameter for comparison with this BigDecimal object. Return Value: This method returns boolean true if and only if the Object passed as parameter is a BigDecimal whose value and scale are equal to that of this BigDecimal object and returns false otherwise. Thus, this function does not return true when it compares 124.0 and 124.0000. Examples:

Input: 
b1 = new BigDecimal("4743.00")
b2 = new BigDecimal("4743.00000")
Output: false

Input: 
b1 = new BigDecimal(4743)
b2 = new BigDecimal("4743")
Output: true

Below programs illustrate equals() method of BigDecimal class: Program 1: Java

// Java program to demonstrate equals() method

import java.io.*;
import java.math.*;

public class GFG {

    public static void main(String[] args)
    {

        // Creating 2 BigDecimal objects
        BigDecimal b1, b2;

        b1 = new BigDecimal("4743.00");
        b2 = new BigDecimal("4743.00000");

        if (b1.equals(b2)) {
            System.out.println(b1 + " and " + b2 + " are equal.");
        }
        else {
            System.out.println(b1 + " and " + b2 + " are not equal.");
        }
    }
}

Program 2: Java

// Java program to demonstrate equals() method

import java.io.*;
import java.math.*;

public class GFG {

    public static void main(String[] args)
    {

        // Creating 2 BigDecimal objects
        BigDecimal b1, b2;

        b1 = new BigDecimal(67891);
        b2 = new BigDecimal("67891");

        if (b1.equals(b2)) {
            System.out.println(b1 + " and " + b2 + " are equal.");
        }
        else {
            System.out.println(b1 + " and " + b2 + " are not equal.");
        }
    }
}
