What is the method for comparing if two BigDecimals are…

In Java, the compareTo() method can be used to compare whether two BigDecimal objects are equal. The compareTo() method returns an integer value that represents the comparison result of the two BigDecimal objects. If the return value is 0, it means the two BigDecimal objects are equal; if the return value is negative, it means the first BigDecimal object is less than the second BigDecimal object; if the return value is positive, it means the first BigDecimal object is greater than the second BigDecimal object.

Here is an example code demonstrating how to compare two BigDecimal objects for equality using the compareTo() method.

import java.math.BigDecimal;

public class BigDecimalComparison {
    public static void main(String[] args) {
        BigDecimal num1 = new BigDecimal("10.50");
        BigDecimal num2 = new BigDecimal("10.5");
        
        int result = num1.compareTo(num2);
        
        if (result == 0) {
            System.out.println("num1 is equal to num2");
        } else {
            System.out.println("num1 is not equal to num2");
        }
    }
}

In the example above, the values of num1 and num2 differ only in precision, but their numerical values are equal. The compareTo() method will return 0, thus the output result is “num1 is equal to num2”.
