Java program output handle

Question

I want to run a compiled Java/C code by an external Java program. Problem is compiled Java/C code directs all input and output to standard devices but I want that external program to handle its input and output in real-time, like a user.

Answer 1

You can use Runtime and Process Class

//Sample Code
Runtime compileRuntime = Runtime.getRuntime();
Process compileProcess = compileRuntime.exec("javac MyClass.java");

and the returned Process class object has an input and output stream.

see this for more details.
