🔔Hello, everyone!

Just a quick reminder that our session will commence in just 10 minutes. Please take a moment to ensure that your working environment is ready for the lab. Let's make this session productive and enjoyable! 😊

Today, we will be advancing to Lab 4. I strongly urge each of you to allocate the next 15 minutes to independently engage with the question and work on it.

Now, we will proceed to tackle a few exam questions.🗓

Choose the correct statement for the code below:

public class AnyProg{
 public static void main(String[]  args){
    int X,  Y;
    X  =  7;
    X++;
    Y  =  X;
    X  =  X  *  3;
    System.out.println("the value of Y is " + Y);
     }
}

Choose the correct statement for the code below:

public static Varargs{
   public static void main(String[]  args){
     go(1,  "hello");
     go(2,  "hello",  "hi");
}
    public static void go(int  X,  String...  Y){
      System.out.println(Y[Y.length  - X] + " ");

}
}

📝EXPLANATION:

#Upon reevaluating the code:

#The variable X is declared and assigned a value of 7.
#X++ increments the value of X by 1, so X becomes 8.
#The value of X is assigned to Y, so Y also becomes 8.
#X is multiplied by 3, resulting in X being 24.
#Finally, System.out.println("the value of Y is " + Y); prints the value of Y, which is 8, to the console.

Therefore, the correct output for this code is:

the value of Y is 8

That was all for today and see you tomorrow ✌️
If you have any question on the lab or on the exam questions you can send it to the group or you can dm this account: @coding2222

🔔Hello, everyone!

Quick reminder that our session will begin in a mere 5 minutes. Please ensure that your working environment is prepared for the lab. Let's make the most of this session together! 😊

Today, we will move forward with Lab 5, which focuses on the fundamentals of Object-Oriented Programming (OOP). These labs and accompanying videos are truly remarkable as they efficiently cover the concepts we have been learning in just 20-30 minutes. I strongly suggest each of you to complete at least one lab per day. This practice will enhance your coding skills because programming is not solely about understanding the concepts; it is about actively applying and coding those concepts.😊

I encourage you to dedicate the next 15 minutes to independently tackle the lab question. Afterward, I will share the video with you.🎥

📝Now we will proceed to some exam question for practice and feel free to ask any questions.

consider the following program:

public class TestProg{
    public static void main(String[]  args){
         int choice;
         Scanner sc = new Scanner(System.in);
         System.out.println("enter choice:  ");
         choice = sc.nextInt();
         switch(choice){
                case 1:
                      System.out.println("Gum ");
                case 2:
                      System.out.println("Coke");
                      break;
                default:
                      System.out.println("Error");
          } 
         System.out.println("Goodbye");   
    }
}

If this program runs and the user enters 1 when prompt for choice so which messages will be displayed by the program before terminating?

Consider a class, RecordAlbum, which has three attributes: the artist name (stored as a String), the record title (stored as a String) and the price (stored as a double). The constructor for this class takes values for the artist name, title and price respectively. Now consider the following array declarationarray declaration

RecordAlbum[] store new RecordAlbum [100);

Which one of the following instructions would add the album "I love Java", by the artists "Charatan & Kans" at a price of £12.99 into the 10th position in the array?

Hello everyone ✋🏻
Today, we will be advancing to Lab 6 I strongly urge each of you to allocate the next 15 minutes to independently engage with the question and work on it.
