Thid is with parameters, and asume that AppRunner.java is in the same directory with the compiled file AppRunner.class.

public class AppRunner {
     public static void main(String[] args) {
          String app = "notepad AppRunner.java";
    try {
         Process process = Runtime.getRuntime().exec(app);
    } catch(Exception e) {}
     }
}

Just run "javac AppRunner.java" followed by "java AppRunner"

hi ovi
thx for the solution.
its working fine.

for ex if i want to run calc.exe file
public class AppRunner {
    public static void main(String[] args) {
         String app = "calc";
   try {
        Process process = Runtime.getRuntime().exec(app);
   } catch(Exception e) {}
    }
}
this opens calc.exe
but if i want to set some integer instead of 0 which is by default.
is it possible??if so how?

I think not. If you run in the command line 'calc.exe 1' you will not get the 1 integer on the calculator input line. So the problem is at the calc.exe program which does not accept parameters.
