java.lang.StrictMath addExact​(int x, int y)

Description

The addExact​(int x, int y) method of StrictMath class returns the sum of its arguments, throwing an exception if the result overflows an int.

Notes:

The addExact​(int x, int y) method of StrictMath class is static thus it should be accessed statically which means the we would be calling this method in this format:

StrictMath.addExact​(int x, int y)

Non static method is usually called by just declaring method_name(argument) however in this case since the method is static, it should be called by appending the class name as suffix. We will be encountering a compilation problem if we call the java compare method non statically.

Method Syntax

public static int addExact​(int x, int y)

Method Argument

Data Type Parameter Description
int x the first value
int y the second value

Method Returns

The addExact​(int x, int y) method returns the sum of the arguments.

Compatibility

Requires Java 1.8 and up

	public static void main(String[] args) {
		
		// Ask user input
		System.out.print("Enter a value:");
		
		// declare the scanner object
		Scanner scan = new Scanner(System.in);		
		
		// use scanner to get the user input and store it to a variable
		int intValue1 = scan.nextInt();		
		
		
		// Ask another user input
		System.out.print("Enter another value:");
		
		// store it to a variable
		int intValue2 = scan.nextInt();	
		
		// close the scanner object
		scan.close();		
		
		// get the result	
		int result = StrictMath.addExact(intValue1, intValue2);
		
		// print the result
		System.out.println("result: "+result);
