When answering a question please:. Read the question carefully. Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it.

Provide an answer or move on to the next question. Let's work to help developers, not make them feel stupid.
Your newCharacterArray variable is declared as referencing a char array.but you never actually create the char array. So newCharacterArray is null.
What you need is something like: char newCharacterArray = new charinStringArray.length;Note that I've put the before the variable, rather than after. Both are valid syntax, but this is more consistent with other usage: it reads as ' newCharacterArray is a reference of type 'char array'. But it's the bit after the = that makes all the difference. Quick tip - don't say 'there appears to be a problem' - tell us what the problem is. What error message you're getting, if you're getting one.
Or what behaviour you're getting that is different to what you expect. It makes it much easier for people to help you, which means you'll get an answer faster. Please note that I've revised my program since your post and have come somewhat closer to figuring out the eventual solution.
I eliminated the problem with excess output. In regards to your first question, each letter should be shifted a number of spaces determined by the ASCII value of the corresponding code letter. For example, if 'a' was shifted by 'f' (6 spaces), the resulting value should be 'g'. Please note that this problem assumes as shift of 'a' to be 1, not 0. We haven't learned about methods yet.
Our professor - by his discretion - started introducing procedural programming these first three weeks of the semester. He reasoned that starting with object-oriented programming and use of methods was too harsh an introduction.

That is an example. That's fine for illustrative purposes, but it isn't what you need to do. You need to write down in English (or other natural language of choice) the EXACT steps take if you were doing this with nothing but pencil and paper. You need to then revise those steps, breaking them down into simpler and simpler components. You need to get to the point where you could hand those instructions to a 10 year old child, walk away, and reasonably expect them to be able to give you the output you desire. Only when the above is done should you consider writing a single line of code. Chu wrote: We haven't learned about methods yet.

He reasoned that starting with object-oriented programming and use of methods was too harsh an introduction. Sigh.I hate professors who figure you should learn the wrong way to do it before introducing you the right way. By that point everyone will have developed all kinds of nasty habits to break. Chu wrote:I want to avoid confusion as much as possible.
In my opinion, there is no appreciable benefit to contextualizing the information presented in the image. At worst, it is ignored. At best, it compliments what I'm trying to present my problem to be. For what it's worth, you have come to this site and asked for help. You were told 'we find it works best when you present your information THIS way'. Replying with 'Nope, I think you're wrong and I'm gonna do it how I want' is very likely to turn off a lot of folk, and they'll not bother helping you any more. Just something to consider.
You're making it way too complicated. If you use the% operator as a number of people have hinted at, encoding can be done with one (1) line of code. Mta san andreas how to car install. For the Caesar cipher, you only need a single for-loop that iterates over the characters in the plaintext string and encodes each one in turn. For the Vignere cipher, I'd use a Map and a formula that again uses% to figure out the proper cipher to use to encode the current plaintext character. The core solution should really only consist of two methods and neither one would be more than 5 lines of code long. Chu wrote: @Fred Rosenberger Thank you for your suggestion. I've already worked through many similar cases in the context of my program.
But if one is giving you the wrong answer, work through it. Step by step. I often will put System.out.println statements in my code - only to remove them later - to validate my assumptions on how the math is working out. Clearly the code was doing something different than what you thought. The trick is to figure out where exactly your assumptions are wrong (and even what your assumptions are).

I would not take him to represent 'we'. As I implied, different people can choose to or choose not to look at the images I've posted. It's as simple as that. It's not just Ulf's opinion. It is a posted in one of our FAQ's: You can find other suggestions here: Nobody will force you to do it.

I was merely suggesting that when you go into someone else's house, you follow their suggestions on how to behave. Ulf has been around here for nine years and has over 38,000 posts. He has the title of 'Marshall', which pretty much means he runs the forums (you can see what the titles mean ). He probably has a pretty good idea how things work best.
Thank you very much, so you are right about formatting errors, I am new to pasting code here and it was tedious to indent all the lines 4 spaces to make them a code snippet. And regarding the rest, yes you are right I am not following best practices because I was coding in ad hoc manner just to see the code work correctly. And about the scanner object I never used it before, I will look into it. I appreciate the time you've took to try and 'parse' my code.
