Example: Program to Add Two Integers
class Main {
public static void main(String[] args) {
int first = 10;
int second = 20;
// add two numbers
int sum = first + second;
System.out.println(first + " + " + second + " = " + sum);
}
}
Output:
Enter two numbers 10 20 The sum is: 30
In this program, two integers 10 and 20 are stored in integer variables first and second respectively.
Then, first and second are added using the + operator, and its result is stored in another variable sum.
Finally, sum is printed on the screen using println() function.
