Question

1. "Palindromes.java"

This program will prompt the user to enter a number ‘N’ and then accept N strings from the
user. These strings will consist only of letters (both uppercase and lowercase), numbers and
spaces. You are required to write a method isPalindrome() that accepts a string and return True
if it is palindrome, otherwise returns False. (Ignoring case and spaces). Print out all the
palindrome strings.
a. Build your isPalindrome() method. It receives a String as input parameter and
return a Boolean type. The method should not have a print statement.
b. To determine if the String is palindrome, first you need to make it all
capital/small cases and remove all spaces. Please avoid the using of character
arrays here. And you cannot change the original string.
c. Based on the use input N, iteratively call the isPalindrome() method to
determine the next input string is palindrome or not.
d. The output should be printed in a single line and palindromic strings should be
separated by a ";", and the case of the letters and the spaces in the input should
be preserved.
e. You need not check for any errors.
f. A palindrome is defined as a string that reads the same forward and backward.
For example, "Race car" is a palindrome.
Sample Run:
Enter the number of strings:
8 Enter the strings:
Race Car
Mountain Dew
BATMAN
Taco Cat
Stressed Desserts
Is Mayonnaise an instrument
swap paws
A Toyotas a Toyota
The palindromes are: Race Car; Taco Cat; Stressed Desserts; swap paws; A Toyotas a Toyota
Generic Grading Guidelines
a. Please make sure you’re only using the concepts already discussed in class. That
is, please try and restrict yourself to loops, selection statements, String methods
that talked on class, arrays, and your own written methods.
b. The programs are worth 50 points each
c. You do not need to perform any form of input type checks.
d. Please make sure you meet the specific requirements, eg. Create the specific
methods/classes, follow data hiding rules.
e. Please make sure that you’re conforming to specifications (program name, print
statements, expected inputs and outputs etc.).
f. Please make sure your code is readable.
g. Please make sure you’ve compiled and run your program before you turn it in. -5
pts will be deducted for each compile error.

Answer 1

To complete this palindrome program in Java, you will need to create a method called isPalindrome() that checks whether a given string is a palindrome or not.

Step-by-step explanation:

Palindrome Program in Java

To complete this program, you will need to implement the following steps:

1. Create a method called isPalindrome() that takes a string as input and returns a boolean value.
2. In the isPalindrome() method, convert the string to lowercase, remove spaces, and check if it is equal to its reverse.
3. In the main program, prompt the user for the number of strings 'N' and then accept 'N' strings from the user.
4. Iteratively call the isPalindrome() method for each input string and print out the palindromes in a single line, separated by a ';'.
5. Print the result as per the provided sample run.

Here's a sample implementation of the isPalindrome() method in Java:

public static boolean isPalindrome(String input) {
String cleanedInput = input.toLowerCase().replaceAll("\\s+", "");
String reversedInput = new StringBuilder(cleanedInput).reverse().toString();
return cleanedInput.equals(reversedInput);
}
