StringTokenizer URGENT help please!
Hi everyone, merry christmas! im having a bit of a problem with a string tokenizer! i wondered if someone could show me how its done please.
im trying to set up my own reserved word - END, which will end the program and print a message.
this is what i have so far, i want it to produce a message when it encounters an END and say how many lines it has processed. (i have a text file which is being opened and it looks for the END in there)
public static void main (String args)
RandomAccessFile inFile = new RandomAccessFile(args, "r");
String line; // a string to contain the line read
while (( line=inFile.readLine() ) != null)
System.out.println("[" + nooflines + " lines processed]");
System.out.println("TPL Finished OK [" + nooflines + " lines processed]");
} catch (IOException e)
System.out.println("An i/o error has occurred ["+e+"]");
i would be grateful for any help.
StringTokenizer URGENT help please continued
What I meant to say was that whenever there is an END in the program itself it will terminate and produce a message. I didnt mean to say that it looks for an END in the txt file. Sorry for the confusion!
Not to sure what exactly you want to do.. but
that can't happen... the == operator doesn't work on literal strings. Use .equals(); or .equalsIgnoreCase();
creating a new reserved word
thanks for your help!
im trying to compose a program that will terminate whenever it encounters an "END" instruction.
This means i am trying to set up my own reserved word for "END" so it understands what to do.
i think this method is called parsing?
can anyone show me how its done please?
