The first step in learning Java JDK environment variable configuration

JDK environment variable Configuration

1. Configure environment variables after installation of JDK computer → properties → advanced system settings → advanced → environment variables

2, system variable → new java_home variable. Variable value fill in the JDK installation directory (my installation directory is C:\Program files\java\jdk1.7.0_713. System variable → find Path variable → editenter%java_home%\bin;%java_home%\jre\bin at the end of the variable value;(Note that the original path of the variable value at the end of there is no; number, if not, first enter; number and then enter the above code) 4. System variables → new CLASSPATH variablevariable values are filled in.; %java_home%\lib;%java_home%\lib\tools.jar (Note that there is a point in the front)5. Test environment variables are configured correctly:============================ the environment variable is configured successfully note: Configure the path of the JDK installation try not to knock, go directly to the path under the copy (reason you understand) ============================ Appendix: This is my first blog, referring to a goddess of the blog written, and then one step at a time to practice, the equivalent of a review, repeated hands to do, you will remember very clearly. Learn to program to your own words (can't remember, because you do not repeat the number of times)
