Do you mean how do you compile a .java file into bytecode?
Or do you mean how do you parse a text file to see which line ends with a ";"?
Your original post is rather ambiguous.


If you are reading lines from a text file, you want some sort of class which reads the lines, either with a file reading class. I presume you are familiar with the part of the Java tutorial which deals with IO (= input and output)? You should find all you need to know about reading from text files there.

You tend to find these file reading and scanning classes are able to read each line from a text file as a String. There ought to be a method in the API telling you whether a String ends with something or not . . .

I hope I have ansered the question you meant to ask.
