Generate source code from text file

Question

Say I have a text file with a simple method:

public void sayHello() {
    System.out.println("HELLO!");
}

Is there anyway to take that code and programatically insert the code into an existing .java file? Or even create a new Java source file with the code provided in the text file? I have heard of solutions where you can generate source code using CodeModel, but I would have to write my own parser to handle all the possible code that would be read from the text file.

@johand. That doesn't even make sense. This is Java, not C++. — , Apr 02 '14 at 12:41

Take a look here: How do I programmatically compile and instantiate a Java class?

You can use the javax.tools to compile the code and then load it into your JVM.

Oracle has a write-up as does IBM.
