Checking for Environment Variable in code

Question

I need to check to see if an environment variable called "MY_TIME" exists on the system. The value of it does not matter(just use 'none'). I need for windows and unix. I believe they should work the same.
The java.lang.system.getenv() is deprecated on 1.3.x, 1.4.x but available on 1.5. I'd like to use another way besides the getenv().
Thanks.
Something like:
if( ENVIRONMENT VAIABLE EXISTS ON MY SYSTEM) {
//do something
}

a-0706-env.htmlI just read that javaworld article. How wonderful that they throw an error. That is so incredibly stupid. It is also incredibly, moronically stupid that nothing is said about that in the JavaDocs. So, I was wrong in my earlier comment about being able to use getenv() in pre 1.5 JVM's. In general, though, deprecated methods aren't unusable. You just need to take care when using them.
You may consider using System.exec() to check env variables. Unfortunately that approach requires that you use system-dependent commands, so you'll have to determine which system you are using at runtime.
