you add this line also and try i am not sure
Runtime rt = Runtime.getRuntime();
Process prcs =rt.exec("inventry.exe");
Thread.sleep(3000);

@kaushalsahil09 - Some more description of error than "I had tried this one but it does`t work" would help.

Hi,
Plz. try it.
class test {
public static void main(String a[]) {
try {
Runtime rt=Runtime.getRuntime();
Process pr=rt.exec("inventry.exe");
}catch(Exception e) {
System.out.println("Error in main() : " +e);
}
}
}
NOTE: This inventry.exe should be in the same folder that of test.class's directory, otherwise above code won't work.

If some import is missing/wrong it'll give a compilation error not runtime..
