Compiling text files in java

Question

I'm trying to make a compiler that takes a .txt file and compile it using java. I've already made one, but that compile only .java files. I have used JavaCompiler class to do that.

Secondly .. to get file I've used this:

Class.forName("CLASS_NAME");

Q:

A:

File aFile = new File("./../../folder1/folder2/test.jpg");
aFile = new File("C:/users/ABC/Desktop/test.png"); //no problems using / in Windows
aFile = new File("/home/ABC/test.pdf");

aFile = new File("D:/Folder");
aFile = new File(aFile, "file2.txt");

As long as none of these folders is your project-folder.
