run shell command from java

I’m trying to run a process with some arguments from inside Java and before running the particular command I print it using println.

Now the problem is from inside Java, the process is not doing good.. its sending some error on the Error Stream instead of output. But If I run the same command printed by Java on screen in console, it works perfectly.

String command="abc -def -hhij";
System.out.println(command);
Process p = Runtime.getRuntime.exec(command);

Anyone know whats going on wrong?

Answer 1

The Runtime.exec(String) using the StringTokenizer, which doesn’t know how to process quoted text. The simplest fix is to use the exec that accepts your parameters in an array.

String[] command={ "abc", "-def", "-hhij"};
Process p = Runtime.getRuntime.exec(command);
