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
