commandline call from java

Question

I'm looking to call the command line from a java program. I have successfully entered the command line using this bit of code

String[] cmd = new String[2]; 
cmd[0] = "cmd /c dir";
Runtime rt = Runtime.getRuntime();
System.out.println("Execing " + cmd[0]);
Process proc = rt.exec(cmd[0]);

However, the actual commands aren't working. I am not too familiar with command line, I have only ever typed directly into it. So my question is how do I pass multiple arguments in? For instance if I wanted to change to C:\ I would have thought I could just add cd\ on the end but this doesn't seem to work? Thanks in advance

Answer 1

use the & symbol. Everything needs to go in at once. For instance: cd .. & echo "test" will go to the previous directory and then echo test.
