my data file contains a list of the names but the list has no commas after each name. I tried making the delimeter ""+"" two spaces but it didnt work. so how would i accomplish making the delimeter equal to some kind of space?

also id like to thank the people in this post who helped. I really appreciate the help!

im a bit confused, you said that you would commas as the separator, well what if in the text file, there are no commas separating the names for example
John Doe
Sue McGonnal
just spaces,
and also in the readFile method, what exactly does the .Split method do?

i am writing a method that returns an array full of students names. The students names are given in a file, so my method called ReadFile, reads the file and adds each line(name) to the array
i'm not sure my code is correct, plus i'm not familiar with writing methods that return and array.
If someone could comment on this code, i would really appreciate it.

hello,
i was given an assigment to write a program that asks for the name of a roster file that has students names in it. Then the program promts for eacht students grade and with those grades does some calculations. At the end a table is outputted with the name of the student and the calculations. the program is include an array. My question is, how do i know how many students are in the file? is there some kind of method that counts the lines of the text file?
this is my first few lines of the program

String DataFileName="";

DataFileName=keyb.askString("What is the name of your roster?");
File inFile=new File(DataFileName);



that last line, does that read the file or just creates a new File instance? and should my array in my program consist of the students names or there grades?

hi, i have this worksheet for class that asks the following question:
Someone wants to create files of debators who will be entering a tournament next month. What instructions should be given about typing these files?
i'm a bit confused about this question because i have never used notepad to write programs or files. Is there a certain way of writing these files in notepad? and what instructions should one give?

Can i send an object to a constructor and then from that constructor send it to a different constructor in the same class?
heres the code

Also, when i parse my string in the if statements, the compilier can't recognise it. is it because of the if statements and can i fix it somehow?
