Crafting a Java Function to Sum Two Numbers

Hello Programmer. Welcome to this blog post. Today, we will be focusing on creating a simple yet important function in Java - adding two numbers. This function is a cornerstone for many complex calculations and logical implementations. Through the upcoming steps, we will guide you on how to develop this function. Let's start coding.

Step 1

First, we need to create a new class in Java. In Java, every application must contain a main method that calls all other methods and procedures. Let's create a new class named AddNumbers:

public class AddNumbers {

}

Step 2

Next, we are going to add the main method to our AddNumbers class. This method is the entry point to any Java code:

public class AddNumbers {

    public static void main(String[] args) {
    
    }

}

Step 3

Now, we will define our method to add two numbers. We'll call this method addNumbers. This method receives two integers as parameters:

public class AddNumbers {

    public static void main(String[] args) {
    
    }

    public static int addNumbers(int number1, int number2){
   
    }
}

Step 4

In the addNumbers method, we will add the two numbers and return the result:

public class AddNumbers {

    public static void main(String[] args) {
    
    }

    public static int addNumbers(int number1, int number2){
        return number1 + number2;
    }
}

Step 5

Now, inside the main method, we are going to call the addNumbers method and print the result:

public class AddNumbers {

    public static void main(String[] args) {
        int result = addNumbers(3, 5);
        System.out.println("The sum of the two numbers is: " + result);
    }

    public static int addNumbers(int number1, int number2){
        return number1 + number2;
    }
}

The final code allows the program to add two numbers and print the result. The function addNumbers can be called with any two numbers you wish to add.

Mathematical principle

This function utilizes the well-known mathematical operation of addition, where the sum of two numbers `a` and `b` (denoted as `a + b`) results in their total. Understanding of this basic arithmetic principle is vital in many programming tasks. In the context of this function, if `a = 5` and `b = 3`, the result would be `8`.
