- Briefly describe each of the following string object methods: RemoveQ1__;. A phrase is a palindrome if, after converting all uppercase letters into lowercase letters and removing all non-alphanumeric characters, it reads the same forward and backward. Alphanumeric characters include letters and numbers. Given a string s, return true if it is a palindrome, or false otherwise. Example 1: Input: s = "A man, a plan, a canal: Panama" Output: true Explanation: "amanaplanacanalpanama" is a palindrome. Example 2: Input: s = "race a car" Output: false Explanation: "raceacar" is not a palindrome..Language: Java Write a program that reads a sentence from the keyboard. Depending on the last character of the sentence, print the message identifying the sentence as declarative (ends with a period), interrogative (ends with a question mark), exclamatory (end with an exclamation point), or other. Hint: you can use charAt() method from the String class to extract the last character of the input line. The character of a String str is at str.length()-1 position. For taking a sentence as input use the nextLine() method from the Scanner class. You have to use if/else if selection. Sample input and output: Sample 1 Input: How are you? Output: Interrogative Sample 2 Input: I am good. Output: Declarative Sample 3 Input: That is amazing! Output: Exclamatory Sample 4 Input: Although, Output: Other Answer:
- using Java. Part B – String Classifier (30%) This program will classify a string as one of the following: a palindrome, a repeated word, or “nothing special”. A word is considered repeated if it repeats only once in a string (e.g., “pizzapizza”). Some palindrome examples are: “racecar”, “aa”, and “aaa”. To determine if it is a palindrome, recommend you make use of the below method. Please make sure this program works for all cases and conditions. /** * This method will return a reversed version of the input string */ static String reverseString(String inStr) { String outStr = ""; if (inStr != null) { int startIndex = inStr.length()-1; for (int i=startIndex; i >= 0; i--) { outStr = outStr + inStr.charAt(i); } } return outStr; }In some circumstances, a class is reliant on itself. That is, one class's object interacts with another class's object. To accomplish this, a method of the class may accept an object of the same class as a parameter.The String class's concat function is an example of this situation. The method is called by one String object and receives another String object as an argument. Here's an illustration:str3 is equal to str1.concat(str2);The method's String object (str1) appends its characters to those of the String supplied as a parameter (str2). As a consequence, a new String object is returned and saved as str3. Create Java code to implement the conditions given.public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string.This problem is an exercise in Java string manipulation. For some mysterious reason, the Java String type does not come with a reverse method. The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is,str = new StringBuilder(str).reverse().toString(); Here's the tester it must pass: @Test public void testPancakeScramble() throws IOException {// Explicit test casesassertEquals("", P2J3.pancakeScramble(""));assertEquals("alu",…

Maybe one day the Java strings will come with the reverse method built in, just like the string data types of all sensible…C# Code: There are two A, B players playing the game. Player A is angry with him, and player B is angry with him. Both s and t include only small English letters and are of equal length. A makes the first move, then B, then A, and so on. Before the start of the game, players are familiar with the content of both the letter s and t characters. These players form one rope during the game. Initially, the character unit w is empty. In each move, the player removes any single letter from the alphabetical order in order and adds this letter any (any position) to the letter w you can add a character to any index. Please refer to the Definitions for more specifications). If in any stage of the game, the character unit w is more than 1 length and is a palindrome, the player who made the last move wins. If even after the end of the game (i.e., when both s and t are empty strings), no one can make a unit of characters w a palindrome, and then player B wins. Given the unit of the letters s, and t,…Create a subroutine that disassembles a simple noun-verb-object phrase into its constituent parts. As an illustration, the sentence "Mary walked the dog" may be deconstructed into the following:Noun: MaryVerb: walkedObject: the dog This function should work with both String objects and StringBuilder objects.
- Part I: PrintVertical.java Write a program that will prompt the user to enter a sentence (string data), read that sentence into your program as a single string, and then finally process the string by calling the method specified below (vertical). 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 r2. A password is called STRONG if it holds all of the following properties: (a) It has at least 8 characters (b) It contains at least one lower case letter, and at least one upper case letter (c) It does not contain any blank space Write down a program that will take a password as input to a string and will print a message indicating whether it is STRONG or WEAK. Sample input: Strange Sample output: The password is WEAK solve in C program languageAssume that sentence is a variable that has been associated with a string consisting of words separated by single space characters with a period at the end. For example: "This is a possible value of sentence."
