Execute a Java program from our Java program

Question

I used

Runtime.getRuntime().exec(\"_____\")

but it throws a IOException as below:

java.io.IOException: Create         


        

Answer 1

I can't remember the exact code that I used to get this to work, but you have to pass "java.exe" (or the equivalent) as the executable, and then the class or jar to run as the parameter, with the correct working directory. So it's not as simple as just calling one method.
