java.math.BigInteger.equals(Object x)

Description Of BigInteger: equals(Object x)

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

BigInteger.equals(Object x) method returns true if and only if the specified Object is a BigInteger whose value is numerically equal to this BigInteger

Code Example Java BigInteger

import java.math.BigInteger;

public class BigIntegerExam {
 public static void main(String[] args) {
  BigInteger bi1 = new BigInteger("123");
  BigInteger bi2 = new BigInteger("123");

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

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

  System.out.println(b1); // output true
  System.out.println(b2); // output false
 }
}
