Core Java || BigInteger & BigDecimal

In Java,BigInteger & BigDecimal and are classes in the java.math package that provides arbitrary-precision integer and arbitrary-precision decimal, respectively.

They are used when working with extremely large or precise numeric values that exceed the capabilities of the primitive data types (double, float, long, etc.).

BigInteger: -

BigInteger is useful in scenarios such as cryptography, number theory, large calculations, or whenever precise integer arithmetic is required.

import java.math.BigInteger;

BigInteger num1 = new BigInteger("12345678901234567890");
BigInteger num2 = new BigInteger("98765432109876543210");

BigInteger sum = num1.add(num2);
BigInteger difference = num1.subtract(num2);
BigInteger product = num1.multiply(num2);
BigInteger quotient = num1.divide(num2);

System.out.println("Sum: " + sum);
System.out.println("Difference: " + difference);
System.out.println("Product: " + product);
System.out.println("Quotient: " + quotient);

BigDecimal: -

BigDecimal is commonly used in financial applications, currency conversions, tax calculations, scientific computations, or any scenario where accuracy and precision in decimal arithmetic are critical.

import java.math.BigDecimal;

BigDecimal num1 = new BigDecimal("1234.56");
BigDecimal num2 = new BigDecimal("7890.12");

BigDecimal sum = num1.add(num2);
BigDecimal difference = num1.subtract(num2);
BigDecimal product = num1.multiply(num2);
BigDecimal quotient = num1.divide(num2, 2, BigDecimal.ROUND_HALF_UP);

System.out.println("Sum: " + sum);
System.out.println("Difference: " + difference);
System.out.println("Product: " + product);
System.out.println("Quotient: " + quotient);
