How would I make a method or a line of code from a string value? Say I typed in "i=1;" in a text field, is there a way to put that text in the compiling code? This is not about assigning values to variables, this is about being able to write a method in a running java program and then implement it. That would be awesome. Thanks in advance.
While I'm not 100% sure, I'm fairly certain this cannot be done.
However, I must ask: Why do you wish to do this? A user could type an erroneous line of code and crash the application, or a malicious piece of code that manipulates the program in an undesirable way.
PS: You could parse it as JavaScript if you wanted... http://download.oracle.com/javase/6/...ide/index.html
... also you can have a look at BeanShell (google is your friend here).
kind regards,

Or the JavaCompiler class would allow you to create a java source program, compile it and execute it within a java program.
I think that Groovy can do this innately, but I have never tried this.
