Setting Classpath for Java ~ mkniit

Java is freely available on Oracle's Website. Download the latest version of JDK (Java Development Kit) on your machine. Do check whether your machine is 32 bit or 64 bit and download that particular Java version. Install JDK on your machine. Once you have installed Java on your machine you would need to set environment variable to point to correct installation directory.

An Environment variable is a dynamic "object" on a computer that stores a value(like a key-value pair), which can be referenced by one or more software programs in Windows. Like for Java, we will set an environment variable with name "java" and its value will be the path of the /bin directory present in Java directory. So whenever a program will require Java environment, it will look for the java environment variable which will give it the path to the execution directory.

Step 1: Environment variable path should be set to point where java binaries have been installed. Refer to your shell if you have trouble doing this.
