+## Java GUI
+
+### GUI Basics
+- [Lecture Notes](lecture-notes/GUI_Basics.ppt)
+
+- [Swing Notes](lecture-notes/Creating_User_Interfaces_Swing.ppt)
+
+- Swing (interface) vs. AWT (event handling)
+
+-```java
+import javax.swing.*;
+
+public class MyFrame {
+public static void main(String[] args) {
+JFrame frame = new JFrame("Test Frame");
+frame.setSize(400, 300);
+frame.setLocationRelativeTo(null);
+frame.setVisible(true);
+frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
+}
+}
+```
+
+-	```java
+import javax.swing.*;
+
+public class MyFrameWithComponents { 
+public static void main(String[] args) { 
+JFrame frame = new JFrame( "MyFrameWithComponen")
+
+JButton jbtOK = new JButton("OK"); // Add a button into the frame 
+frame.add(jbtOK); 
+
+frame.setSize(400, 300); 
+frame.setDefau1tC10seOperation(JFrame.EXIT_ON_CLOSE); 
+frame.setLocationRe1ativeTo(nu11); // Center the frame 
+frame.setVisib1e(true);
+}
+}
+```
+- [JFrame with inheritence](programs/MyFrame1.java)
+
+### Layout Manager
+- For arraning a position into containers
+
+- [FlowLayout](programs/ShowFlowLayout.java)
+
+- [GridLayout](programs/ShowGridLayout.java)
+
+- [BorderLayout](programs/ShowBorderLayout.java)
+
+- `Color` class
+- ```java
+ Color mycolor = new Color(228, 100, 50);
+ // how to set for button
+ mybutton.setBackground(Color.mycolor);
+ mybutton.setForeground(Color.mycolor);
+ ```
+
+### JPanel
+- In `JFrame` we add a component `JPanel`
+
+- [TestPanels](programs/TestPanels.java)
+
+### Event-Handling in Java (Event-Driven Programming)
+
+- [Lecture Notes](lecture-notes/Event-Driven_Programming.ppt)
+
+- Event-driven programming (depends of action) <-> procedural programming (step by step)
+
+- [HandleEvent](programs/HandleEvent.java)
+
+- [HandleEvent1](programs/HandleEvent1.java) with the use of Inner Classes
+
+-```
+User ActionObjectGenerated
