There are four overloaded versions of the exec() command:



public Process exec(String command);

public Process exec(String [] cmdArray);

public Process exec(String command, String [] envp);

public Process exec(String [] cmdArray, String [] envp);

The string "command" is prompt.

The easy way is to use System.getProperty("java.version"). You can get lots more information about the environment using system properties too. Here's more information:
