## What is Swing?
Swing is a built-in GUI library that comes with JDK. It's a lightweight and easy to use library. It's also an extension of AWT. Swing supports a lot of features and its the ideal library for building simple and interactive desktop GUI apps. JavaFX is the successor of Swing but it has a learning curve and is mostly used for web applications whereas Swing can be used for small-scale GUI applications .
## How to use Swing?
Since Swing is a built-in library, we can directly import it from our java file without the need of Gradle or Maven.
It can be imported using ```import javax.swing.*```
Once you add that line of code to your java file, you can start using Swing's elements in your Java code.
## Creating a window using Swing
In Swing, we use a JFrame to store our UI elements. It's the basic window where our UI elements are placed. Without a JFrame, we won't be able to see any Swing elements that we code into our app.
Let's create a JFrame now.
``` JFrame frame = new JFrame("newwindow")```
And that's it, we've created a JFrame but if you try to run this code in a main function in your java code, you'll see nothing. It's because by default, JFrame is set to invisible. You need to make it visible by manually typing ```frame.setVisible(true);```.
## Adjusting the size of the window
Now we've made a JFrame. If you run the code, you'll notice that it looks something like this.
This is because we didn't set the size of the window. To set the size of the window, add ```frame.setSize(x,y);``` where x is the width and y is the height of the frame.
I'm setting it to 400x400.
Now it looks nice and neat.
## Closing the window
If you close the window, you'll notice that the code still doesn't terminate. It still runs. To avoid this, add ```frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);``` to your code.
## Adding components to the JFrame
So, we've made a
