java.math.BigInteger.divideAndRemainder(BigInteger val) was introduced in Java 8. This method returns an array of two BigInteger after applying division operation between the BigInteger calling this method and the BigInteger passed as a parameter to the other method. Here, First BigInteger of the array represents a result of the division (this / val) and Second BigInteger Represents remainder of this division operation (this % val).
Syntax:
public BigInteger[] divideAndRemainder(BigInteger val)
Parameters: This method takes a mandatory parameter val of type BigInteger, which acts as the divisor to apply division operation.
Return Value: This method returns an array of two BigInteger containing the quotient (this / val) as the first element, and the remainder (this % val) as the second element.
Exception: The method throws ArithmeticException if null or 0 is passed in parameter.
Example:
Input: 42245, 23 Output: [1836, 17] Input: 25556, 444 Output: [57, 248] Explanation: In input two BigInteger are given. The first one is the dividend, which calls the method, and the second is the divisor, which is passed as parameter. When applying division operation, as a result, an array of quotient and remainder is returned as output. These are also of BigInteger type
Below programs illustrates divideAndRemainder() method of BigInteger class:
Program 1:
// Java program to demonstrate divideAndRemainder() method import java.math.*; public class GFG { public static void main(String[] args) { // Creating a BigInteger object BigInteger dividend = new BigInteger("25556"); BigInteger divisor = new BigInteger("444"); // applying divideAndRemainder() method BigInteger[] answers = dividend.divideAndRemainder(divisor); // print results System.out.println("Dividend : " + dividend); System.out.println("Divisor : " + divisor); System.out.println("Quotient : " + answers[0]); System.out.println("Remainder : " + answers[1]); }} |
Dividend : 25556 Divisor : 444 Quotient : 57 Remainder : 248
Program 2:
// Java program to demonstrate divideAndRemainder() method import java.math.*; public class GFG { public static void main(String[] args) { // Creating a BigInteger object BigInteger dividend = new BigInteger("32345678987"); BigInteger divisor = new BigInteger("1537862842"); // applying divideAndRemainder() method BigInteger[] answers = dividend.divideAndRemainder(divisor); // print results System.out.println("Dividend : " + dividend); System.out.println("Divisor : " + divisor); System.out.println("Quotient : " + answers[0]); System.out.println("Remainder : " + answers[1]); }} |
Dividend : 32345678987 Divisor : 1537862842 Quotient : 21 Remainder : 50559305
Program 3: To demonstrate ArithmeticException
// Java program to demonstrate divideAndRemainder() method import java.math.*; public class GFG { public static void main(String[] args) { // Creating a BigInteger object BigInteger dividend = new BigInteger("32345678987"); // Creating 0 as divisor BigInteger divisor = new BigInteger("0"); // print both numbers System.out.println("Dividend : " + dividend); System.out.println("Divisor : " + divisor); try { // applying divideAndRemainder() method BigInteger[] answers = dividend.divideAndRemainder(divisor); // print results System.out.println("Quotient : " + answers[0]); System.out.println("Remainder : " + answers[1]); } catch (Exception e) { System.out.println("Exception: " + e); } }} |
Dividend : 32345678987 Divisor : 0 Exception: java.lang.ArithmeticException: BigInteger divide by zero
