ProcessBuilder in Java

问题

I´m studing about this subject in this page, but I can´t find the solution, how can I execute programs in cmd using ProcessBuilder? I want to compress, open, delete a file with 7zip using the command line. I have this code as example, but doesn´t work, cmd starts but doesn´t create the compress file:

String[] commands=
   {"cmd.exe", "7za", "a", "-t7z", "test.7z", "Test.txt", "/C", "start"};
ProcessBuilder pb = new ProcessBuilder(commands); 

回答1:

The problem is a little bit in Java (start() missing), a little bit in 7za (command line garbled)

new ProcessBuilder("7za", "a", "-t7z", "test.7z", "Test.txt").start();

This command works only if 7za is in your PATH...

If not you have to specify its path, under Windows:

new ProcessBuilder(
   "C:/Program Files/7-Zip/7za.exe", "a", "-t7z", "test.7z", "Test.txt").start();

Seven zip help:
