Setting up Java on your PC
Download the latest JDK (Java Development Kit) from Sun
Unzip it, I suggest \jdk115 instead of \jdk1.1.5 because it makes windows directory management easier.
Set up your “path” variable to point to the \jdk115\bin directory (control panel / system / environment) --- sometimes use “classpath”
Use “> javac” to compile, and “> java” to run.
