Java Configuration Java Environment variables, installing Eclipse__java

Java programs rely on JDK, just like C # program dependencies. NETFramework the same.

So before developing, you have to install the JDK (Javadevelopkit) in Win7 or Linux, including some Java tools, and the JRE (javaruntimeenvironment) Java Runtime Environment.

System: Windows7

JDK version: jdk1.7

Installation path: C:/java

When you install the JDK, the public JRE shown above is the same as the subsequent separately installed JRE. So it's OK to just install one.

Follow the steps above to show the configuration interface of the environment variables.

New, adding

Variable name Java_home

Variable value is C:\Java\jdk1.7.0_15

The variable name is best capitalized.

Modify path to add the JDK's Bin directory to the path directory.

%java_home%\bin;%java_home%\jre\bin;

Open the cmd command window, execute Javac, eject a series of commands, this succeeds.
