Lab 5A (Solved)

Question 1

    public static void simpleWhileLoop() {
        // Define constants
        final int MIN_VALUE = 1;
        final int MAX_VALUE = 10;
        
        // Initialize counter variable
        int num = MIN_VALUE;
        
        // Loop until counter exceeds maximum value
        while (num <= MAX_VALUE) {
            // Print current number
            System.out.println(num);
            
            // Increment counter
            num++;
        }
    }

Question 2

    private static final int START_NUMBER = 1; // IDA
    private static final int END_NUMBER = 10; // IDA
    
    public static void simpleDoWhile() { // IDA
        int counter = START_NUMBER; // IDA
        
        do { // IDA
            System.out.println(counter); // IDA
            counter++; // IDA
        } while (counter <= END_NUMBER); // IDA
    }

Question 3

public void simpleForLoop() {
    // Define constants
    final int START = 1;
    final int END = 10;
    
    // Iterate from START to END and print each number
    for (int i = START; i <= END; i++) {
        System.out.println(i);
    }
}

Question 4

private static final int START_NUMBER = 1; // IDA

public static void simpleDoWhile(int upperLimit) { // IDA
    int counter = START_NUMBER; // IDA
    
    do { // IDA
        System.out.println(counter); // IDA
        counter++; // IDA
    } while (counter <= upperLimit); // IDA
}

Question 5

public void simpleForLoop(int upperLimit) { // IDA
    final int START = 1; // IDA
    
    for (int i = START; i <= upperLimit; i++) { // IDA
        System.out.println(i); // IDA
    } // IDA
}

Question 6

public static void simpleWhileLoop(int upperLimit) { // IDA
    final int START_NUMBER = 1; // IDA
    
    int counter = START_NUMBER; // IDA
    
    while (counter <= upperLimit) { // IDA
        System.out.println(counter); // IDA
        counter++; // IDA
    }
}

Question 7

    private static final int QUIT_VALUE = 0; // IDA
    
    public static void sumOfEven() { // IDA
        Scanner scanner = new Scanner(System.in); // IDA
        int sum = 0; // IDA
        int number; // IDA
        
        do {
            System.out.print("Enter a number (0 to quit): \n"); // IDA
            number = scanner.nextInt(); // IDA
            
            if (number % 2 == 0 && number != QUIT_VALUE) { // IDA
                sum += number;
            }
        } while (number != QUIT_VALUE); // IDA
        
        System.out.println("The sum of even numbers is " + sum); // IDA
        scanner.close();
    }

Question 8

public static void sumOfOdd() {
    int number;
    int sum = 0;

    // Create scanner
    Scanner input = new Scanner(System.in);

    // Start of do-while loop
    do{
        // Number input
        System.out.print("Enter a number (0 to quit): \n");
        number = input.nextInt();

        // Check if the number is odd
        if (number % 2 == 1) {
            sum += number; // Add the odd number to the sum
        }

    } while (number != 0); // Loop until 0 is entered

    // Print the sum of odd numbers
    System.out.println("The sum of odd numbers is " + sum);
