Java BigInteger compareTo() method

The compareTo() method of Java BigIntegerclass is used to compare two BigIntegervalues.This method is provided in preference to individual methods for each of the six boolean comparison operators (<, == ,> ,>=, !=, <=). This method computes (x.compareTo(y) <op> 0) , where <op> is one of the six comparison operators.

Syntax:

Parameter:

val-BigInteger to which this BigInteger is to be compared

Returns:

This method returns -1, 0 or 1 as this BigInteger is numerically less than, equal to, or greater than val.

Note: This method is specified by compareTo in interfaceComparable <BigInteger>.

Example

import java.math.BigInteger;

public class BigIntegerCompareToExample {
public static void main(String[]  args){
// create  2BigInteger objects
BigInteger big1= new BigInteger("8");  
BigInteger big2 =new BigInteger("4");  

// createint object
int  result;

//compare bigInteger big1 with big2
result = big1.compareTo(big2);   

if(result == 0)
System.out.println("Both values are equal");
else if( result== 1)
System.out.println("First value is greater");
else if( result== -1)
System.out.println("Second value is greater");

}
}
