Check if BigDecimal is empty in Java.

In Java, you can use the compareTo method of the BigDecimal class to determine if a BigDecimal object is empty. If the compareTo method returns 0, it means the object is equal to 0, which indicates it is empty.

Here is an example:

import java.math.BigDecimal;

public class Main {
    public static void main(String[] args) {
        BigDecimal num1 = new BigDecimal("0");
        BigDecimal num2 = new BigDecimal("10");

        System.out.println(isEmpty(num1));  // true
        System.out.println(isEmpty(num2));  // false
    }

    public static boolean isEmpty(BigDecimal number) {
        return number.compareTo(BigDecimal.ZERO) == 0;
    }
}

In the example above, the isEmpty method takes a BigDecimal object as a parameter and compares it with BigDecimal.ZERO using the compareTo method. If the comparison result is 0, it means the object is empty, so it returns true; otherwise, it returns false.
