Java Code in a text file

Question

Hi,
I need an information if whether anything like this can be done in java or not !!
The requirement is to place the jave code statements into a text file and dynamically execute these statements which have been placed in the file. for eg: if a text file "test.txt" contains a statement
System.out.println("Hello world"); without the class being defined or the main method being defined. I need to execute this statement and print out hello world on the console.
is this possible ???
I would be using JDK 1.2 or 1.3 for this but certainly not 1.4.x and above
please do let me know if this problem can be tackled in anyway !!
Thanks in advance !

Answer 1

I'd suggest first checking to see if the code in question would also be valid code in an interpreted language like Javascript, Groovy, or BeanShell.
If it is, then use an interpreter for the appropriate language, an interpreter written in Java and which you can plug into the Java program you're using.
Otherwise, I suppose you could wrap a class and method around the code, and compile and run that.
