Advertisements


Description

The java.math.BigInteger.equals(Object x) compares this BigInteger with the specified Object for equality.

Declaration

Following is the declaration for java.math.BigInteger.equals() method

public boolean equals(Object x)

Overrides

equals in class Object

Parameters

  • x - Object to which this BigInteger is to be compared

Return Value

This method returns true if and only if the specified Object is a BigInteger whose value is numerically equal to this BigInteger.

Exception

  • NA

Example

The following example shows the usage of math.BigInteger.equals() method

package com.tutorialspoint;

import java.math.*;

public class BigIntegerDemo {

public static void main(String[] args) {

        // create 2 BigInteger objects
        BigInteger bi1, bi2;

        bi1 = new BigInteger("123");
        bi2 = new BigInteger("123");

        // create 2 boolean objects
        Boolean b1, b2;

        // compare bi1 with bi2
        b1 = bi1.equals(bi2);

	// compare bi1 with an object value 123, which is not a BigIntger
        b2 = bi1.equals("123");

        String str1 = bi1 + " equals BigInteger " + bi2 + " is " +b1;
	String str2 = bi1 + " equals object value 123 is " +b2;

	// print b1, b2 values
        System.out.println( str1 );
        System.out.println( str2 );
    }
}

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

123 equals BigInteger 123 is true
123 equals object value 123 is false
