BigInteger Class divideAndRemainder() method

  • divideAndRemainder() method is available in java.math package.
  • divideAndRemainder() method returns BigInteger array of 2 elements that contain quotient that is calculated by using (this BigInteger)/(BigInteger val) followed by the remainder that is calculated by using (this BigInteger) % (BigInteger val).
  • divideAndRemainder() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • divideAndRemainder() method may throw an exception at the time of calculating the remainder.
    ArithmeticException: This exception may throw when the given parameter holds value 0.

Syntax:

    public BigInteger[] divideAndRemainder(BigInteger val);

Parameter(s):

  • BigInteger val – represents the value by which this BigInteger is to be divided and generate remainder.

Return value:

The return type of this method is BigInteger[], it returns an array of BigInteger of two element of "BigInteger" type and the quotient is calculated by using (this BigInteger)/ (BigInteger val) and the remainder is calculated by using (this BigInteger) % (BigInteger val).

Example:

// Java program to demonstrate the example // of divideAndRemainder(BigInteger val) method of BigInteger import java.math.*; public class DivideAndRemainderOfBI { public static void main(String args[]) { // Initialize two variables divi, divisr String divi = "120"; String divisr = "4"; // Initialize two BigInteger objects BigInteger b_int1 = new BigInteger(divi); BigInteger b_int2 = new BigInteger(divisr); // Display b_int1 and b_int2 System.out.println("b_int1: " + b_int1); System.out.println("b_int2: " + b_int2); System.out.println("divideAndRemainder(BigInteger): "); // divides this BigInteger (b_int1) by the // given BigInteger (b_int2) and return the BigInteger[] // of two values (Quotient, Remainder) BigInteger[] div_rem = b_int1.divideAndRemainder(b_int2); System.out.println("Quotient div_rem[0]: " + div_rem[0]); System.out.println("Remainder div_rem[1]: " + div_rem[1]); } }

Output

b_int1: 120
b_int2: 4
divideAndRemainder(BigInteger): 
Quotient div_rem[0]: 30
Remainder div_rem[1]: 0
