Is There A Way To Call Another Java Program Within A Java Program

[SwissR]

Hi everyone,

I basically have two Java programs and am wondering if i can complete my first programs run and then call my second program within the first like calling a css file in html.

I dont really want to have to add the class of one program to the other and fiddle around with it. I know I can call them in the command prompt window but if possible I would like to execute them both through one instance if possible.

I know I can call them in the command prompt window

That implies that both classes have a main( ... ) method; why not call that method yourself? e.g.

YourFirstClass.main(null); 
YourOtherClass.main(null);

Note that I didn't pass any arguments to the main( ... ) methods; you decide whether or not that is correct.

kind regards,

Jos

Im a little confused by what you mean.
So your saying that I can call the class and main method of one program within another without actually having to paste the class into said program?

I mean im calling one program via its main class so do I call the other programs class and then its main method through that...

I would have thought I would have had to reference a directory, or am I getting the wrong idea here...?

Yes. There's nothing special about a main( ... ) method; if the jvm can call it, you can call it as long as the class is visible to the jvm; but it has to be because you wrote in your OP that you can call the class (through its main( ... ) method) from the command line.
