Beginner Java Exercise: Check Palindrome

A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward. Allowances may be made for adjustments to capital letters, punctuation, and word dividers.

In this simple exercise, we're going to be checking for palindromes.

Examples of palindromes:

noon
moon noom
14455441

The program prompts the user to enter a sentence or a word. It then calls the isPalindrome() method to check whether the word is actually a palindrome. It sets two variables, low and high to 0 and the length of the string - 1 respectively (remember that the string starts at 0; that's why you need the -1).

It compares the two characters at low and high locations. If at any point through the iteration the characters at the low and high locations do not equal each other the isPalindrome() method will return false.

Beginner Java Exercise: Sentinel Values and Do-While Loops

In my previous post on while loops, we used a loop-continuation-condition to test the arguments. In this example, we'll loop at a sentinel-controlled loop. The sentinel value is a special input value that tests the condition within the while loop. To jump right to it, we'll test if an int variable is not equal to 0. The data != 0 within the while (data != 0) { ... } is the sentinel-controlled-condition. In the following example, we'll keep adding an integer to itself until the user enters 0. Once the user enters 0, the loop will break and the user will be displayed with the sum of all of the integers that he/she has entered. As you can see from the code above, the code is somewhat redundant. It asks the user to enter an integer twice: Once before the loop begins, and an x amount of times within the loop (until the user enters 0). A better approach would be through a do-while loop. In a do-while loop, you "do" something "while" the condition...

Programming Language Concepts Test Questions/Answers

One of the easiest methods that I use to learn new topics is by creating notes on the subject and then by turning those notes into questions and answers. Remembering answers to questions just seems more natural. I was able to memorize 323 questions and answers in a matter of a couple of days. I wanted to start doing this for some topics that I find pretty interesting. To begin, here are some questions and answers to Programming Language Concepts (PLC). I'm reading your mind right now and the answer is yes, there will be more. 1. Name 3 reasons for studying PLC. - Better understanding of current programming languages - Advancement of computing - Increased capability to express ideas - Increased capability to learn new programming language. - Better understanding of which programming language to choose.  2. Name the 5 programming domains and languages best suited for each. - Scientific (Fortran, ALGOL 60) - Business (COBOL) - AI (Lisp, Scheme, Prolog) - Web (PHP, ...
