Question

A palindrome is a word, phrase, or sequence that reads the same backward as forward, e.g., madam or nurses run.

In this program, ask the user to input some text and print out whether or not that text is a palindrome.

Create the Boolean method isPalindrome which determines if a String is a palindrome, which means it is the same forwards and backwards. It should return a boolean of whether or not it was a palindrome.

Create the method reverse which reverses a String and returns a new reversed String to be checked by isPalindrome.

Both methods should have the signature shown in the starter code.

Sample output:

Type in your text: 
madam
Your word is a palindrome!

OR

Type in your text: 
hello
Not a palindrome :(

Coding Portion:

public class Palindromes
{
/**
* This program lets the user input some text and
* prints out whether or not that text is a palindrome.
*/
public static void main(String[] args)
{
// Create user input and let user know whether their word is a palindrome or not!
  
}
  
/**
* This method determines if a String is a palindrome,
* which means it is the same forwards and backwards.
*
* @param text The text we want to determine if it is a palindrome.
* @return A boolean of whether or not it was a palindrome.
*/
public static boolean isPalindrome(String text)
{
// Your code goes here!
}
  
/**
* This method reverses a String.
*
* @param text The string to reverse.
* @return The new reversed String.
*/
public static String reverse(String text)
{
// Your code goes here!
}

}

Code:

Output:

Raw Code:

import java.util.*; // Importing required packages
public class Palindromes{
   public static void main(String[] args) {
       System.out.println("Type in your text:");
       Scanner scan = new Scanner(System.in); // Creating Scanner instance for taking input from user.
       String str = scan.next(); // Taking string from user and store it in str variable.
       if (isPalindrome(str)){ // Checking if a str is palindrome or not.
           System.out.println("Your word is a palindrome!");
       }
       else{ // If it is not a palindrome
           System.out.println("Not a palindrome :(");
       }
   }
   // isPalindrome function for checking if a given string is palindrome or not.
   public static boolean isPalindrome(String text){
       String reverse_text = reverse(text); // Calling reverse function with text as a parameter.
       if (text.equals(reverse_text)){ // Checking if a text and reverse_text are equal or not
           return true; // Returning true
       }
       else{
           return false; // Returning false
       }
   }

   public static String reverse ( String text){
       String rev = ""; // Declaring rev variable.
       for (int i = text.length() -1;i>=0;i--){ // Iterate through each character in text in reverse order.
           rev += text.substring(i,i+1); // adding each character to rev.
       }
       return rev; // Returning the rev.
   }
}
