My java programming class is asking me to create a program with these rules. I cannot even get the psuedocode down to start writing the program.
Write a program that asks the user for the name of a file. The program should display only the first five lines of the files contents. If the file contains fewer than five lines, it should display the files entire contents.
Any help will be appreciated
Where are you stuck? Break the problem down into smaller pieces...do you know about java IO? Do you know how to ask the user and get user input?
I am not confident in my abilities. I keep having to double back to earlier chapters to write the material. I am a complete novice. So currently no to all your questions.
I recommend to tackle each at once. The problem has specific criteria:
- asks the user for the name of a file
- read file
- Display first five lines (or all if less than 5)
Programming is a workflow often consisting of trial and error - so I encourage you to try something that would tackle each of the above in turn. I am sure your book has examples and descriptions on how to do each of the above. If not, concentrate on a specific problem, make an effort, and post a specific question should you have problems or questions.
