Program Plan Intro

Palindrome

Program Plan:

• Import required package.
• Define “PalindromeTestProgram” class.
  • Define “isPalindrome” method with arguments char array “a” and “int” type variable “used”.
    • Convert to string and on remove irrelevant characters in one shot.
    • Assign index to “0”.
    • Compute string length.
    • Check condition using “while” loop. This loop performs up to index is less than or equal to “strLength / 2”.
      • If the characters at each index is not match, then returns the result as “false”.
    • Otherwise, returns “true”.
  • Define main function.
    • Create object for scanner class.
    • Assign user option.
    • Check condition using “while” loop. This loop will perform up to the condition is “true”.
      • Display user prompt statement for sequence of characters from user.
      • Read input string from user.
      • Compute the char array.
      • Check if the user entered text is palindrome or not by calling the method “isPalindrome”.
        • If it is match, then display the statement “The entered string is a Palindrome.”.
        • Otherwise, display the statement “The entered string is not a Palindrome.”
        • • Display user prompt statement for test another string.
          • Read option from user.
          • If the user option is “n” or “N”, then exit the program. Otherwise read another string from user.
