Hi,
I need to write a program that caculates the logical lines of code in  any program that is written using Java langauge. I have jus started  learning Java. I think I can use String Tokenizer for my program.

Basically, I have to look for the keywords in java language, ;, to count the number of lines in the program. Is String Tokenizer is alone sufficient for this program or I have to use some other function to do  this. My friends told I can try with split() and ReplaceAll()
function. But I don't know the usage of these 2 functions. So can you help by giving me small sample program. Later I can work on it and develope it on my own. What is stream tokenizer? How can I use in my project?


Thanks


For a short utility program to analyse a text file that's written to a particular format (e.g. to analyse a program source file), I would probably not recommend you use Java;  Java is ideal for larger applications and systems but on shorter tasks you'll find a language such as Perl or Python is much more productive, even though you might feel that you're being unfaithful to Java by using another language  

Python solution:

Code:

import sys info = open(sys.argv[1]).read() sofar = 0 for char in info:    if char == ";": sofar += 1 print "There were "+str(sofar)+" semicolons"

For comparison, I would expect the code to be 4 to 5 times longer than this in Java ....

Hi,
Thanks for that piece of information. But I have to do this using Java only. So, I like to know which one is more suitable Stream or String Tokenizer?

Thanks

If you have to do this job (inappropriately) in Java, then I would suggest you open a stream and read byte by byte, checking for the ";" character.   There seems little point in you reading (for example) each line into a string for you to then have to start breaking that string down with a tokenizer.
