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.

PC #3. String Reverser (page 1073) Write a recursive method that accepts a string as its argument and returns the string in reverse order. The method should return the same string if the string length is less than 2 characters long. The main program should ask the user to enter a string, which is then reversed using the above method and printed on the console. The program then prompts the user to enter another string. If the user enters QUIT (case insensitive), then exit the program. Test Case 1 Please enter a string for reversal or type QUIT to exit:\nabcdENTERReversed string: dcba\nPlease enter a string for reversal or type QUIT to exit:\nquitENTER Test Case 2 Please enter a string for reversal or type QUIT to exit:\naENTERReversed string: a\nPlease enter a string for reversal or type QUIT to exit:\nENTERReversed string: \nPlease enter a…If your first name starts with a letter from A-J inclusively: Write a recursive method that takes a string as argument and determines if the string has more vowels than consonants.

The method header ispublic static String dec2Hex(int value)Write a test program that prompts the user to enter a decimal number and displaysits hex equivalent.Exercise-3: Write a recursive and iterative methods to convert a decimal number to its binary equivalent string. The iterative algorithm (in pseudo-code) for converting a decimal integer into a binary integer as follows: 1. If the integer is 0 or 1, its binary equivalent is 0 or 1. 2. If the integer is greater than or equal to 2 do the following: 3. Divide the integer by 2. 4. Separate the result into a quotient and remainder. 5. Divide the quotient again and repeat the process until the quotient is zero. 6. Write down all remainders in reverse order as a string. 7. This string is the binary equivalent of the given integer. // Recursive decimal to binary method public static String dec2binRecursive(int n) { if (n<2) return n+ " ". else return dec2binRecursive(n/2) + n%2; } a) Write the Complete program for above Recursive decimal to binary method Algorit b) Iterative decimal to binary method8.Write a static method recReplace that takes a String str, a String sub1, and a String sub2 as parameters, and replaces all occurrences of sub1 in str with sub2.

You must process the sentence by calling the method rather than processing the string directly in your main method. Write a void method, vertical, which receives a string as a parameter and prints each letter of the string to the screen on separate lines. Example Execution (user input in green) Please enter a sentence: Hey there! Your sentence printed vertically is: H e t h e rPublic class Utilities { getDigits Method: public static java.lang.String getDigits(java.lang.String str) Returns a string with the digits (if any) present in the str parameter. You can assume str will never be null. You can use Character.isDigit() to determine whether a character is a digit. You may not use an auxiliary method in order to implement this method. Your implementation must be recursive and you may not use any loop construct. From the String class, the only methods you can use are length(), isEmpty(), charAt() and substring. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: str - Returns: String with digits or empty string
