AP Computer Science Exam Question

/**
 * This program calculates the sum of two numbers and returns the result.
 * The numbers and their sum are passed as parameters to the method.
 *
 * @param num1 the first number
 * @param num2 the second number
 * @return the sum of num1 and num2
 */
public static int calculateSum(int num1, int num2) {
    return num1 + num2;
}

public static void main(String[] args) {
    // Test the calculateSum() method
    int result = calculateSum(5, 7);
    System.out.println("The sum is: " + result);
}

Explanation

The given program defines a method calculateSum that takes two integers (num1 and num2) as parameters. It calculates the sum of these two numbers and returns the result.

In the main method, the calculateSum method is tested by passing 5 and 7 as arguments. The returned result is stored in the variable result. Finally, the sum is printed using System.out.println statement.

When executed, the program will output:

The sum is: 12

This indicates that the calculateSum method correctly calculates the sum of the provided numbers.
