Java Web Start is a way of installing applications without having to download the application file. This is particularly useful if you are trying to run a program that requires Java Runtime Environment (JRE). JRE is required to run some programs such as Minecraft, Chrome, Firefox, etc. However, it is possible to use Java Web Start even if you don’t have JRE installed. In fact, there are several ways to make sure that Java Web Start works properly.

Java is one of the most popular programming languages used today. While it is free to use, there are many different versions of the software available. Some people prefer to download the full version while others opt for the lightest weight version possible. If you want to install Java, here are some things to consider.
Downloading the entire package will save you time because you won’t have to download each individual component separately. However, you might end up having multiple files on your computer. This could cause problems down the road. For example, if you delete one of those files, you’ll lose access to the program.
If you’re looking for a lightweight version of Java, try OpenJDK. You can find it online.

1. Download the latest version of Java from Oracle’s website.

3. Open the extracted folder and double-click on jdk-8u40-linux-x64.bin. This will start the installation process.
4. Follow the instructions displayed on screen.
5. Once done, restart your computer.
6. Check whether Java is installed successfully.
Before installing Java online, make sure your firewall allows downloads. If you are having trouble getting it to work, try saving the download locally. You’ll want to double-click on the downloaded file to start the installation process. Once the installation completes, you’ll be able to use the Java version command to verify whether the program installed correctly. After you’ve finished the installation, restart your computer to ensure that the changes take effect.
