Java subtract BigInteger

In this Java core tutorial we learn how to use the java.math.BigInteger.subtract() method to subtract two BigInteger values.

How to subtract two BigInteger values

To subtract BigInteger value we can use the java.math.BigInteger.subtract() method which returns the subtraction result of a BigInteger object and given argument BigInteger object.

SubtractBigIntegerExample.java

import java.math.BigInteger;

public class SubtractBigIntegerExample {
    public static void main(String... args) {
        BigInteger value1 = new BigInteger("987654321");
        BigInteger value2 = new BigInteger("123456789");

        BigInteger result = value1.subtract(value2);

        System.out.println(value1 + " - " + value2 + " = " + result);
    }
}

The output is:

987654321 - 123456789 = 864197532

Happy Coding 😊
