Unlock the Power of Java’s Math.subtractExact() Method
Accurate Calculations Made Easy
When it comes to performing precise arithmetic operations in Java, the Math.subtractExact() method is an essential tool in your toolkit. This static method, part of the Math class, allows you to subtract one integer or long value from another with guaranteed accuracy.
Understanding the Syntax
The syntax for Math.subtractExact() is straightforward: Math.subtractExact(num1, num2). Here, num1 is the value from which num2 is subtracted, and both values must be either int or long data types.
What to Expect: The Return Value
The Math.subtractExact() method returns the difference between num1 and num2. This result is crucial in various mathematical operations, such as calculating distances, differences, or remainders.
Putting it into Practice: Example 1
Let’s see how Math.subtractExact() works with int and long variables. In this example, we’ll calculate the difference between two values using the Math.subtractExact() method.
Handling Exceptions: Example 2
But what happens when the result of the subtraction exceeds the data type’s range? In such cases, the Math.subtractExact() method throws an exception. For instance, if we try to subtract -1 from the maximum int value, the method will throw an integer overflow exception.
