Java Process.waitFor() vs Process.exitValue()

Is there a difference between java.lang.Process.waitFor() and exitValue()?

exitValue throws an IllegalThreadStateException if the subprocess is not terminated and returns the exit value if its terminated.

WaitFor will block the calling thread until the subprocess is terminated and returns immediately if it has already been terminated.

So i would say that they will both behave the same when the subprocess is already terminated but will behave differently when it is still running. If the subprocess is running , exitValue will throw an excpetion and waitFor will block the calling thread.
