How to Create a GUI Component for Java in Just 7 Steps

It becomes a turbulent issue for web site managers when they come across some issues in their Java website. Unlike PHP, it is a secured language, which provides an arranged procedure of coding. However, the customization is not an easy task, when it comes to Java. But, if you are trying to create a GUI component for your Java website then this tutorial can help you.

Technically, you will have the need of Java swing library, which is based on Java Abstract Widget Tool Kit. For your information, ‘AWT’ is an old platform. This platform is dependent on GUI toolkit. So, there is a freedom to use the components of GUI library like Button, textbook, etc, which sets you free from creation of components from zero.

Here is a video, which can be followed for creating the swing component:

On looking at the above-mentioned graph, you might be coming across the question that what is container class. Noticeably, the components in swing are JComponent and can be added in container classes. Therefore, you should know the container classes at first.

Container classes

Technically, you need a class with competency of carrying other components and container classes are that classes. You can also take the reference from its name. So, you need to have a container class for making a GUI. There are three kinds of class: Panel, Frame, and Dialog. The panel is basically a container, which stands for organizing components on a window. The frame class is window, which contains components and possesses independent title & icons. Well, you will remember dialog class as a pop up window, which will beget a pop up on requirement of display. However, this class is not like Frame class in case of functionalities.

Here is an example that you need to see in order to learn how to design GUI in Java.

Step 1: Copy Below Mentioned Code Into An Editor

import javax.swing.*;

class gui{

public static void main(String args[]){

JFrame frame = new JFrame("My First GUI");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setSize(300,300);

JButton button = new JButton("Press");

frame.getContentPane().add(button); // Adds Button to content pane of frame frame.setVisible(true);

}

}

Step: 2 Now, you need to save this code snippets, compile, and run the code.

Step: 3 In this step, you need to add a button in your frame by copying further mentioned code into an editor.

import javax.swing.*;

class gui{

public static void main(String args[]){

JFrame frame = new JFrame("My First GUI");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setSize(300,300);

JButton button1 = new JButton("Press");

frame.getContentPane().add(button1);

frame.setVisible(true);

}

}

Step 4: Now, you need to execute the code, which will bring this button.

Step 5: In this step, you can try to add two buttons. You just need to copy and paste the below given code in an editor.

import javax.swing.*;

class gui{

public static void main(String args[]){

JFrame frame = new JFrame("My First GUI");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setSize(300,300);

JButton button1 = new JButton("Button 1");

JButton button2 = new JButton("Button 2");

frame.getContentPane().add(button1);

frame.getContentPane().add(button2);

frame.setVisible(true);

}

}

Step 6: Congratulations, now you just need to save, compile, and run this program.

By following this process of GUI component creation, you will be able to create a spectacular component. In case, this process is not easy to execute for you then you should take Java web development services from a renowned company. It will help you in enhancing the competency of your website. And, offshore Java application development will not be much costly for you. So, just find skilled developers and create your GUI component.
