Add Two Numbers
Learn how to add two numbers in Java:
Example
int x = 5;
int y = 6;
int sum = x + y;
System.out.println(sum); // Print the sum of x + yExplanation: We create two integer variables ( x and y ) and assign them values. The expression x + y is stored in the variable sum . Finally, we print the result with System.out.println() .
Add Two Numbers with User Input
Learn how to add two numbers with user input:
Example
import java.util.Scanner; // Import the Scanner class
class MyClass {
public static void main(String[] args) {
int x, y, sum;
Scanner myObj = new Scanner(System.in); // Create a Scanner object
System.out.println("Type a number:");
x = myObj.nextInt(); // Read user input
System.out.println("Type another number:");
y = myObj.nextInt(); // Read user input
sum = x + y; // Calculate the sum of x + y
System.out.println("Sum is: " + sum); // Print the sum
}
}Explanation: Here we use the Scanner class to read two numbers from the keyboard. The method nextInt() reads an integer from the user. We then add the two numbers together and print the result.
