- 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.Write a java program for the followingExample for call by value.Example for call by reference. Give source code and output alsowrite a code in java that has a row of 3 and a column of 3 and prints out the even numbers but if there is an odd number it instead prints it the space blank
- Write a recursive Java method that calculates the sum of n positive integer numbers. The math function is: f(n) = 1 + 2 + 3 + … + n. Jack, Peter and John were exploring a tunnel which allows only one person to pass through. Jack entered the tunnel first, followed by Peter. John entered the tunnel the last. The tunnel has a dead end. So the team has to turn back and retrieve from the tunnel one by one. Write a Java program based on a suitable data structure to simulate this process.Write a Java Program: Sometimes some words like "localization" or "internationalization" are so long that writing them many times in one text is quite tiresome. Let's consider a word too long if its length is strictly more than 10 characters. All too long words should be replaced with a special abbreviation. This abbreviation is made like this: we write down the first and the last letter of a word and between them, we write the number of letters between the first and the last letters. That number is in decimal system and doesn't contain any leading zeroes. Thus, "localization" will be spelled as "l10n", and "internationalization» will be spelled as "i18n". You are suggested to automatize the process of changing the words with abbreviations by using the Java program that implements the static method capitalization(). At that, all too long words should be replaced by the abbreviation and the words that are not too long should not undergo any changes. Input The first line contains…Create a java program Using only one 2-D array (table) with equal odd sizes for its rows and columns, write a complete java program for a magic square. Use the sample output below as your basis for uniformity. Note: A magic square has its rows, columns, and diagonals sum to be ALL EQUAL in value. Input: Enter size = 3 Output: 3 x 3 magic square 8 1 6 3 5 7 4 9 2 Note: All rows, columns, and diagonal sum = 15 Try again (Y/N) Y Input: Enter size = 5 Output: 5 x 5 magic square 17 24 1 8 15 23 5 7 14 16 4 6 13 20 22 10 12 19 21 3 11 18 25 2 9 Note: All rows, columns, and diagonal sum = 65 Try again (Y/N) N Thank you.

- Write a Java program to recursively determine if a given string is a palindrome. Make sure the program is done recursively. Definition of a palindrome Links to an external site. Input Data: Repeatedly, enter one string at a time at the keyboard alternatively, you may set up an input data file and get the data from the file Stop the inputting, when the user does not want to enter any additional strings Processing: Set up a method to recursively determine if a given string is a palindrome. Output Data: The attached screenshot displays sample output, when a program is run based on the above problem statement:Write a java recursive method called printNumPattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. Ex. If the input is: 12 3 the output is: 12 9 6 3 0 3 6 9 12Please help me solve this with java .... just the HangMan HangMan instruction class : • HangMan is a game in which a player tries to guess a word based on a given hint. For example, if the given hint is “movie”, then the player must guess a movie name. If the given hint is a “country”, then the player must guess a country name, and so on.• The game starts by showing a message on the screen that shows the hint and all letters in the word but obscured as dashes (-). Then, the game will allow the player to guess 5 letters. If the player gives a letter that actually exists in the word, then this letter will be revealed. Afterwards, the game will ask the player to give the answer. If the given answer is correct, then the game will show a message that the player has won 5 points. Otherwise, the game will show a message that the player has lost. Below is one possible game scenario, in which the word is “iron man”, and the hint is “movie”. Note that the text in green color is the…
- Write a Java Program to Check if a given Number is Perfect Number.
