Write a JAVA program that checks phrases to determine if they are palindromes. A palindrome is a word, phrase, or sentence that reads left-to-right the same way it reads right-to-left, ignoring all punctuation and capitalization. For example, the statement “Madam, I’m Adam” is a palindrome as the response of “Eve.” Use a method to determine if a String is a palindrome. Test a single word non-palindrome, a single word palindrome, a phrase that is not a palindrome, and a phrase that is a palindrome. Print the phrase and whether it is a palindrome or not.
Some simple palindromes are “racecar,” “taco cat,” and “A man, a plan, a canal, Panama!” There are a few different approaches for the test; choose one of your liking.
Hint: extract all letters, change the remaining letters to lowercase, then test if the phrase is a palindrome.
2. Write a java program which will input an integer value from the user (Use Scanner class). Your program will have mathOper() method in addition to the main() method.The main() method will be responsible for:a. extracting the 1's digit (ones), the 10's digit (tens), and any digits larger than the 10's digit. For instance, if the input is 3562, the 1's digit would be 2, the 10's digit would be 6, and the remaining digits would be 35.b. call the mathOper() method with these 3 values,c. print the results to the screen.The mathOper() method will make the following calculations:a. Multiply the 1's digit by 7, subtract the result by 2 and then divide that by 5.b. Add 3.5 to the 10's digit, multiply the result by 4.3 and then divide that by 2.c. Subtract 5 from the remaining digits, multiply the result by 3, find the remainder after dividing that by 7, and then add 6 to the remainder value.d. Add the 3 values obtained from ‘a’, ‘b’, and ‘c’ operations.e. Return the final value.Sample output…
Write a Java program, GradeApp that reads a series of exam scores given as integers in the range 0 to 100. Display the total number of grades and the number of grades in each letter-grade category, followed class average (as a percentage with 2 decimal place):
Use the value -1 as a sentinel value to indicate the end of the input. (The -1 value is used only to end the loop. Please do not use it in the calculations.)

There is a very simple solution to keeping Tic-tac-toe fresh and interesting, though, and it has been thought up by a group of mathematicians. It’s being called Ultimate Tic-tac-toe and simply embeds a Tic-tac-toe board in each of the nine squares of the original game. Now instead of just winning the main board, you also need to win each of the smaller boards first until you have a line of three. New Rule: You can only place a mark on the board determined by the position of your opponent’s last placed mark. So, if they put an X or O in the top right corner of a square, your next move must occur in the top right board. By adding that rule the game is no longer about winning a single board, it’s about tactically managing up to 9 games at once and plotting ahead. You still win by marking three squares in a row, but that now involves winning three games. The effects of the New Rule: 1: Your opponent can force you to…arrow_forward

Edit the file Easter java.arrow_forwardNote: Please answer the question in Python only: Citizens of Byteland play the game regularly. They have blocks, each of which represents some integer from 0 to 9. These are arranged together in a random fashion without having to remember that the first block is never 0. Once they form a number, they are read in reverse order. check that the number and its reverse are the same. If both are the same, the player wins. Such numbers are called palindromes.

If the user enters a single letter, check if that letter is in the secret word (case-insensitive). The user can make up to 6 letter guesses in a round. If the user guesses a letter they have already guessed, print the message “You've already guessed that letter!” and don’t count it as one of their 6 guesses. Go straight to step 6. If the user enters a word, check if the word matches the secret word (case-insensitive). Word guesses should not…arrow_forward
