Exploring BigDecimal operations in Java

Report a typo

Given the following snippet of Java code, can you identify the statements which are true about BigDecimal?


import java.math.BigDecimal;
import java.math.BigInteger;

public class Test {
  public static void main(String[] args) {
    BigInteger bigInt1 = new BigInteger("123456789101112");
    BigInteger bigInt2 = new BigInteger("987654321010220");
    
    BigDecimal result = new BigDecimal(bigInt1).divide(new BigDecimal(bigInt2), 2, BigDecimal.ROUND_HALF_UP);
    System.out.println(result);
  }
}

Select one or more options from the list

The result variable will store a BigDecimal object that is the result of precise division between two BigInteger variables, with the decimal rounded up to the nearest half.

The BigDecimal class in Java allows arithmetic operations on arbitrary-precision decimal numbers with full control over precision and rounding.

The divide() method of the BigDecimal class in the code can throw ArithmeticException if precise quotient could not be calculated.

BigDecimal class is mutable therefore the value of result can be changed after initialization.

The BigDecimal instances created in the code are immutable.
