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

The answer is simple all you have to do is put the code -

$ process p = Runtime.getRuntime().exec("javac factorial.java"); in the try catch block

The code would look like this -

try
{
process p = Runtime.getRuntime().exec("javac factorial.java");
}
catch(IOException e)
{
e.printStackTrace();
}

Hey I think this should work. Atleast for me it did work
