- 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; }Write a method that finds the number ofoccurrences of a specified character in a string using the following header:public static int count(String str, char a) For example, count("Welcome", 'e') returns 2. Write a test program thatprompts the user to enter a string followed by a character then displays the numberof occurrences of the character in the string.Q1) Write a method that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, "silent" and "listen" are anagrams. Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram". Note: The header of the method is as follows: public static boolean isAnagram(String s1, String s2) Sample Input #1: Enter two strings: Silent listen Sample Output #1: The string “Silent” and “listen” are anagrams. Sample Input #1: Enter two strings: teach peach Sample Output #1: The string “teach” and “peach” aren’t anagrams.
- This is a python programming class 1. tmp = "Good Day"; print( tmp[2:4]) tmp = "John Doe"; print( tmp[5: ] ) Exact Output: 2. sentence = "Hi Bye" tmp = list(sentence); print(tmp) Exact Output: 3.Use a string method to PRINT True if a string cost contains only numbers. Use a string method to PRINT True if a string name contains only letters. Use a string method to PRINT True if a string tmp contains only numbers or letters. Use a string method to PRINT True if a string tmp contains only whitespace. 4. Use a string method to PRINT how many times the letter 'e' appears in a string called sentence print( ) 5. Use a string method to PRINT the number of characters in a string tmp print( ) 6. Use a string method to PRINT the location of the LAST period in a string tmp Use a string method to PRINT the location of the…In java language Before we write a class which is used to describe objects, let’s practice manipulating an object by calling its methods. Complete the class LeetMaker class using String methods. Remember that all the String methods are accessors. They do not change the original String. If you want to apply multiple methods to a String, you will need to save the return value in a variable. Complete the class by doing the following: Print the word in lowercase Replace "e" with "3" (Use the unmodified variable word) Print the changed word In the changed word, replace: "t" with "7" Print the changed word In this newest changed word, replace: "L" with "1" (uppercase L with the number 1). Then, print the final changed word (with all the replacements) Print the length of the word The code to print the original word is already included for you. Do not change that statement. You will need to use the replace() method multiple times. Then print the final String. Remember that replace is an…Write a method that finds the number of occurrences of a specified character in a string using thefollowing header:public static int countLetter(String str, char ch)Write a test program that prompts the user to enter a word and a letter of the alphabet. Theprogram should then count and display the number of occurrences of the letter in the word. Asample dialog for the program is shown below:
- Write a method that accepts a String object as an argument and displays its contents backward.For instance, if the string argument is “gravity” the method should display -“ytivarg”.Demonstrate the method in a program that asks the user to input a string and then passes itto the method.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:Write a method with the following header to format the integerwith the specified width.public static String format(int number, int width)The method returns a string for the number with one or more prefix 0s. The size of thestring is the width. For example, format(34, 4) returns 0034 and format(34,5) returns 00034. If the number is longer than the width, the method returns thestring representation for the number. For example, format(34, 1) returns 34.Write a test program that prompts the user to enter a number and its width, anddisplays a string returned by invoking format(number, width).
- Java: The class will contain the following static methods: reverseS – A method that displays a string reversely on the console using the following signature: public static void reverseS(String s) printSub1 – print all substrings of a string (duplicated substrings are allowed, but loops are not allowed). The method signature: public static void printSub1(String s) printSub2 – print all substrings of a string (duplicated substrings are not allowed, but loops are allowed). The method signature: public static void printSub2(String s) Note: All methods should be RECURSIVE. Any predefined classes that are based on Set are not allowed. Allow the user to input the string! In the main method, read a string from the user and output the reversed string and substrings to the screen: Sample Run: Please input a string: abcd The reversed string: dcba The substrings of the input string: abcd abc ab a b bc b c bcd bc b c cd c d The substrings of the input string: a ab abc…write a public static method named replaceFirst that takes in a String s and a char c as arguments. The method will return a modified String replacing the first character with the one that was passed in. (Do not print out the String) Special cases: If s is null, the method should return null. If s is the blank string, “”, the method should return the blank string. Example: Replace.replaceFirst(“make”, ‘t’); Returns: “take” Replace.replaceFirst(“a”, ‘x’); Returns: “x” Java tests: Test replaceFirst(null, char c) replaceFirst("", char c)keyboard_arrow_up replaceFirst(String s, char c)Unit testkeyboard_arrow_downComputer Programming Java Write a method named stringTimes that is passed a String parameter word and a positive integer num. The method returns a larger string that is a num copies of word concatenated together. For example, if word is "hello" and num is 3 then "hellohellohello" is returned.
