Change default JAVA path

Once you installed JAVA 1.7 or 1.8, your default JAVA path is changed. But, it is not listed in Environment Variable Properties. To change to another JAVA path, you can simply do the following.

In Windows,

1. go to "C:\Windows\System32" 
2. delete "java.exe"
3. add JAVA path to environment variable
4. open command prompt
5. check JAVA version (java -version)
