Methode who execute an other java program

Question

Hi!
Is there anyone who know a method who can execute an other java program from an applet?
Thanks
Julien

Answer 1

Depends where the classes of the other program are located. A java program is just a collection of classes, with one particular one regarded as the main one. If you know the main class of the other program at compile time you can just invoke it like any normal method.
Something like:
MyOtherProgram.main(new String[]{"first parameter", "second parameter"});(assuming that it's just a standard "command-line" kind of program.)
If you don't know the class name at until runtime it's still farly straightforward:
something like
import java.reflect.*;
String theOtherProgram = ......
Class otherP = Class.forName(theOtherProgram);
String [] params = {"first parameter", "Second parameter"};
Method theMain = otherP.getMethod("main", new Class[]{params.getClass()));
theMain.invoke(null, params);
