How to Set Environment Variables in Windows

Hi Guys,

You know that we can retrieve the environment variables using System.getProperty("JAVA_HOME"); like this. It is easy.

Can anyone tell me how to create an environment variable using System class or is there any alternate java API to create environment variable. Please let me know.

My requirement is that I want to create the environment variable as follows

DEV_HOME

D:/Java/DEV

Are you talking about Java System properties (get and set through System.get/setProperty) or Environment Variables (read-only, get through System.getenv)?

You can set the former, not the latter (unless you start a new process through Runtime.exec(), for which you can specify a custom environment.
