I just used PATH system variable and had the jdk1.5.0_18\bin &nbsp;point to it apart from other folders. This way I was able to run my simple Java programs without any problem. I also learnt that Java installs the interpreter file java.exe in %SYSTEM_ROOT%/system32 folder. &nbsp;I deleted that file java.exe but my simple one liner class continued to compile from anywhere using javac and run using java.<br />
<br />
Why then do we need these two variables , &nbsp; JAVA_HOME and CLASSPATH?<br />
<br />
Thanks<br />

Why do we need JAVA_HOME and CLASSPATH

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
