Applet viewer is a command-line program to run a java applet. It helps you to test an applet before you run it in the browser. The applet’s code gets transferred to the system & then the Java Virtual Machine (JVM) of the browser & executes that code.
In this article, we will look into the process of installing a Java Applet Viewer on Linux.
Installing Java Applet Viewer on Linux:
Follow the below steps to install Java Applet Viewer on Linux:
Step 1: For installing Java Applet Viewer, you need to first download Java JDK 8. Because Java gives applet only up to JDK version 9 only.
Step 2: Open Terminal and execute the below command:
sudo apt install openjdk-8-jdk openjdk-8-jre
This command will install Java JDK 8. Or if you already installed it, it will give the following output.
Step 3: Write a sample applet code. You can write the following code also. Save it by the name Demo.java in a folder which name is also Java.
Java
import java.awt.*;import java.applet.*;Â
public class Demo extends Applet{Â Â public void init()Â Â {Â Â Â Â Â Â Â Â setForeground(Color.white);Â Â Â Â Â Â Â Â setBackground(Color.blue);Â Â }Â Â public void paint(Graphics g)Â Â {Â Â Â Â g.drawString("Welcome To Java Applet",40,50);Â Â }} |
Step 4: Write the following commands one by one to execute the applet program.
cd Java/ ls Demo.class Demo.java javac Demo.java appletviewer Demo.java
Step 5: As a result, the program will be executed & give output.
Hence Java Applet Viewer is successfully installed.
