Hello everyone! 👋

In our previous class, we covered the concept of the GUI class in Java. Today, we will explore one of the major aspects of GUI programming: color and the subclasses of JComponent.
Let's dive in and learn more about these topics.

Painting the Java GUI Canvas: Exploring Colors and JComponent Subclasses

As a Java beginner, understanding the fundamentals of color and the various JComponent subclasses is crucial for creating visually appealing and interactive Graphical User Interfaces (GUIs). Let's dive in and explore this exciting topic together! 💻

Colors in the Java GUI Palette 🌈
The java.awt.Color class is your gateway to the vibrant world of colors in Java GUI programming. This class provides a wide array of static color constants, such as Color.RED, Color.BLUE, and Color.GREEN, allowing you to easily incorporate these classic hues into your user interfaces.

But that's not all! You can also create custom colors by specifying the desired Red, Green, and Blue (RGB) values, ranging from 0 to 255. For example, to create a warm, orange-ish color, you can use:

Color myCustomColor = new Color(255, 165, 0);

Now, let's see how we can apply these colors to our GUI components.

Subclasses of JComponent: Painting the GUI Canvas
The javax.swing.JComponent class is the foundation for all Swing GUI components. It provides a rich set of subclasses, each with its own unique visual and functional capabilities. Here are a few examples:

1. JButton: This component allows you to create clickable buttons with custom text and colors. Try it out:

JButton myButton = new JButton("Click me!");
myButton.setBackground(Color.CYAN);
myButton.setForeground(Color.DARK_GRAY);

2. JLabel: Use this component to display text or icons with your desired color scheme.

JLabel myLabel = new JLabel("Hello, Java GUI!");
myLabel.setForeground(new Color(255, 165, 0));

3. JPanel: Panels are versatile containers that can hold other components and be styled with colors.

JPanel myPanel = new JPanel();
myPanel.setBackground(new Color(173, 216, 230)); // Light blue

By combining the power of colors and the wide variety of JComponent subclasses, you can create visually stunning and interactive Java GUIs that will impress your users.

Greetings everyone!

In our previous lessons, we explored writing Java code for a GUI. Today, we will demonstrate a more efficient method by utilizing a drag and drop approach. We have selected a video tutorial that provides a step-by-step guide on using this technique in IntelliJ. Please watch the video below and follow along to easily work on your GUI.

Feel free to ask any questions.
Let's get started! 💪

Hello everyone,👋

I have some important updates regarding our plans for the coming days.

As we all know, the 2nd year students will be taking their OOP final exam next week. To help prepare for this exam, we have a few key activities planned:

1. Practice Questions: Starting this Sunday, we will be conducting question and answer sessions to go through practice questions that will help prepare you for the upcoming exam.

2. Previous Year Exam Papers: We will be sharing previous year exam papers. This will give you an opportunity to review the type of questions that have been asked in the past and understand the exam pattern.

Hello everyone,

These exams are from previous years for OOP, and it's often the case that exams are repeated or have similar content. Therefore, use these exams as a guide, and we will also work on more questions.

Greetings everyone,👋

As per our schedule, we will be focusing on practicing questions for the OOP final exam today. The question and answer session is set to commence at 2:30(mata) local time.

See you all there!

NOTE:
#The difference between Abstruction and encapsulation

Abstraction hides the implementation details from users whereas, encapsulation wraps (binds) data and code into a single unit.

NOTE:
#The difference between method Overloading and Overriding

Method overloading is a feature that allows a class to have more than one method with the same name, provided their parameter lists are different.
Method overriding, on the other hand, allows a subclass to provide a specific implementation for a method that is already defined in its parent class, enabling runtime polymorphism.

NOTE:
#The difference between checked and Unchecked exception

Checked exceptions are those exceptions that are checked at compile-time, and the programmer must handle them using try-catch blocks or by declaring them in the method signature using the throws keyword. Unchecked exceptions, on the other hand, are not checked at compile-time and include exceptions that are instances of RuntimeException and its subclasses. These do not need to be explicitly handled by the programmer.

NOTE:
#The four types of access modifiers in java

-The private modifier: restricts access to the members of the class so that they are only accessible within the same class.

-The protected modifier: allows access within the same package and subclasses.

-The default (no modifier): access level allows access only within the same package.

-The public modifier: allows access from any other class. These access levels help in defining the visibility and accessibility of class members.

Greetings Everyone,👋

We've covered the basics of Java and we are now planning to share tips on platforms for upcoming summer projects. We're preparing projects of varying difficulty levels to help students learn through hands-on experience.

In the programming world, the projects you've worked on are crucial for internships and jobs. Employers often ask to see your GitHub and LinkedIn to assess your progress. Therefore, we encourage everyone to work on projects suited to their skill level. We'll provide helpful videos to learn the necessary platforms.

Stay tuned for more details on our summer project plan. Watch the videos we'll be sending soon.
