- Palindrome Detector: a palindrome is any word, phrase, or sentence that reads the same forward and backward. Here are some well-known palindromes: Able was I, ere I saw Elba A man, a plan, a canal, panama Desserts, I stressed Kayak Write a Boolean method that uses recursion to determine whether a String argument is a palindrome. The method should return true if the argument reads the same forward and backward. Demonstrate the method in a program.Repeating String Write a method that takes a String and an int and return a String that is the original String repeated n times. For example, repeatString("Famous", 3) should return "FamousFamousFamous" The method signature should be public String repeatString(String str, int n) public String repeatString(String str, int n) { //declare a string variable //set up statements for repeating n number of times //create the appropriate return statement }In the class String, the substring method inserts a String into another String. -True or -False

- Please code in pythonUse Object oriented programmingWrite a method names "letterFinder" that gets a string and a letter argument,checks and prints if the string contains the letter or not. Please note that the user must enter the string and the letter to the program.PART G: COUNT HIGiven a string str, output the number of times the string “hi” appears anywhere in the string. Methods to use: substring(), length(), equals()Testing cases:abc hi ho => 1 ABChi hi => 2 hihi => 2 hiHIhi => 2 h => 0 hi => 1 Hi is no HI on ahI => 0 hiho not HOHIhi => 2Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
