Get network status Java project using swing classes in netbeans

By Pawan kumar

The purpose of this project is to assist users in checking their computer's network connectivity status. It serves as a practical illustration of how to perform network-related tasks using Java.

Before utilizing this package, it's essential to consider the following key points:

1. To initiate your development journey, ensure your environment is correctly configured. This involves installing and configuring NetBeans with the necessary Java Development Kit (JDK) and libraries.

2. Familiarize yourself with the Swing library as it will be used to create the user interface for the network status application.

3. Possess expertise in developing graphical user interfaces (GUIs) using Swing, encompassing the integration of elements like labels, buttons, and text fields.

4. Acquire fundamental knowledge of networking, including checking network status, working with IP addresses, and performing network-related tasks.

5. Develop an understanding of the InetAddress class, especially when working with IP Addresses.

 

To commence, open NetBeans and create a new project named 'NetworkStatus.' Inside this project, create a class also named 'NetworkStatus.'

Next, create a function named 'NetworkStatus().' This function will be utilized from the main function. Begin by specifying the frame size and attaching a panel to it. Place a button labeled 'Check Network Status' on the frame, enabling users to verify the connection status. Add a close button to terminate the frame, along with two labels. The first label will display the project's title, 'Network Status Checker,' and the second label will display the network status message, which will change dynamically.

The two buttons can be made functional by implementing the ActionListener. If the close button is clicked, the frame will be closed. On the other hand, clicking the 'Check Network Status' button triggers the 'updateNetworkStatus()' method. In this method, the IP address of the provided hostname is obtained using the 'getByName()' method of the InetAddress class. The 'isReachable()' method is then used to verify if the function is reachable.

If a network connection is established, the 'checking' label on the frame updates to 'Connected to the Internet.'

If the network status is not connected, the 'checking' label changes to 'not connected.'

In case of an error while checking the network connection, the label changes to 'error checking.'
