Unlock the Power of Java: A Step-by-Step Guide to Adding Integers
When it comes to programming in Java, understanding the basics is crucial for building a strong foundation. One essential concept is working with operators, particularly the addition operator (+). In this article, we’ll explore a simple yet powerful example that demonstrates how to add two integers in Java.
Setting the Stage: Declaring Variables
Let’s start by declaring two integer variables, first and second, and assigning them values of 10 and 20, respectively. This sets the stage for our addition operation.
The Magic Happens: Using the + Operator
Next, we’ll use the + operator to add first and second together. The result is stored in a new variable called sum. This is where the magic happens, and our program starts to take shape.
Bringing it to Life: Printing the Result
Finally, we’ll use the println() function to print the value of sum to the screen. This is where we get to see the fruits of our labor and witness the power of Java in action.
The Complete Program
Here’s the complete program that adds two integers in Java:
public class AddIntegers {
public static void main(String[] args) {
int first = 10;
int second = 20;
int sum = first + second;
System.out.println(sum);
}
}
