Getting Started In Java Environment Setup

This chapter will cover the Java Environment Setup. This is the most important thing to do to start learning Java. We will cover everything we need to do to properly setup the Java environment on our PC or laptop. I will explain it in a simple way.

Local Environment Setup In Java

If you are decided to set up your machine for the Java programming language, this section will show you how to download and install Java. Here are the steps you need to take to set up the environment.

The first thing you need to do is download the Java SE Development Kit, which you can get here Java SE Development Kit. Download a version that works with your computer’s operating system.

Follow the steps to download Java and then run the .exe file to put Java on your computer. Once you’ve installed Java on your computer, you’ll need to set environment variables to point to the right installation directories.

Java Environment Setup – Setting up Windows Path

Assuming you’ve installed Java in C:\Program Files\Java\jdk directory –

  • The first thing to do is go to ‘My Computer’ right click and select ‘Properties’.
  • Second step is to click Environment Variables from the ‘Advanced’ tab.
  • Lastly, alter the ‘Path’ variable so that it also contains the path to the Java executable. For example, if the path is currently set to ‘C:\WINDOWS\SYSTEM32’, then change your path to read ‘C:\WINDOWS\SYSTEM32;c:\Program Files\java\jdk\bin’.

Setting up the path for Linux, UNIX, Solaris, and FreeBSD

The Environment variable PATH should be set to point to where the Java binaries have been installed. If you don’t know how to do this, look at the documentation that came with your shell.

For example, if you are using bash as your shell, then you would add the following line to the end of your ‘.bashrc: export PATH = /path/to/java:$PATH‘.
