Parameter:

x ? Object to which this BigInteger is to be compared.

Returns:

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

Example

import java.math.BigInteger;
public class BigIntegerEqualsExample{
public static void main(String[] args){
// create 2 BigIntegerobject
BigInteger big1,big2;

// assign values to big1,big2
big1= new BigInteger("111"); 
big2= new BigInteger("111");  

// create 2 booleanobjects
Boolean b1,b2;	

// compare big1 with big2
b1= big1.equals(big2);   

// compare big1 with an object value 111, which is not a bigInteger
b2 =big1.equals("111");  

String str1=big1+ " equals BigInteger "+big2+" is "+ b1;
String str2=big1+ " equals object value 111 is" + b2;

System.out.println(str1);   
System.out.println(str2);   
}
}
