Alternative to java.lang.Runtime.exec() that can execute command lines as a single string?

Question

I am calling java.lang.Runtime.exec(...) but this seems to accept the command lines as an array and I want to use a single string.

How can I do the same using a single string?

Answer 1

From the linked Javadocs:

envp - array of strings, each element of which has environment variable settings in the format name=value, or null if the subprocess should inherit the environment of the current process.

So just pass in null for the second parameter, and the environment will be inhereted.
