Solved in 3 steps with 1 images
- Write an application that reads a five-letter word from the user and produces every possible three-letter string that can be derived from the letters of that word. For example, the three-letter words produced from the word “bathe” include “ate,” “bat,” “bet,” “tab,” “hat,” “the” and “tea.”Add a static method, public static void changeLetter (StringBuilder sb, char letter) Convert all occurrences of the letter variable in the StringBuilder to upper case. Write in java and use test case example as reference.JAVA PROGRAM FLAMES GAME (SEE ATTACHED PHOTO FOR THE PROBLEM AND EXAMPLE) Implement the method interface Flames in has the following methods: public int countLetters(String name1, String name2); - this method returns the total leftover letters between name1 and name2 public char flames(int numLetters); - this method returns the letter equivalent to the numLetters - example if numLetters is 10 is will return the letter 'M' public String letterEquivalent(char flames); -returns the String equivalent of variable flames. Below is the reference for the variable flames F - Friends L - Lovers A - Affectionate M - Marriage E - Enemies S - Sweethearts
- Create an implementation of your Range abstract data type called WordRange. When you are finished, your range should work in a Java for each loop like so: // prints "Hello," and "World!" for(String word : new StringRange("Hello, World!")) { System.out.println(word); }The String class is provided in the Java library.Provide your own implementation for the following methods (name the newclass MyString2):public MyString2(String s);public int compare(String s);public MyString2 substring(int begin);public MyString2 toUpperCase();public char[] toChars();public static MyString2 valueOf(boolean b);A "mad-lib" is a fill-in-the blank game. One player writes a short story in which some words are replacedby blanks. For each word that is removed, the appropriate part of speech is noted: e.g. noun (person/-place/thing), adjective (word that describes a noun), verb (an action, e.g. eat), adverb (modifies a verb, e.g.quickly). Then, before reading the story, the story-writer asks the other player to write down a word of theappropriate part of speech for each blank without knowing the context in which it will be used. In this way,a humorous (sometimes) or non-sensical (usually) story is created.Write your own mad-lib. It must have at least three blanks in it. Now write a Python program that doesthe following:- Using the input() syntax (see the section "Reading Strings from the Keyboard" from the course read-ings) for reading strings from the console, prompt the user to enter a word of the appropriate part ofspeech for each blank in your program. Have a different, appropriately named…

If it is hollow, it contains another doll (which can also be hollow or solid). Given the supplied Doll class, implement a recursive method named show that returns a String representing the chain for dolls, for example Natasha contains Tanya contains Peter public class Doll{ private String name; private Doll dollInside; /** * Constructs a hollow doll with the doll it contains. */ public Doll(String theName, Doll theDoll) { name = theName; dollInside = theDoll; } /** * Constucts a solid doll. */ public Doll(String theName) { name = theName; dollInside = null; } public boolean isSolid() { return dollInside == null; } public String getName() { return name; } public Doll getDollInside() { return dollInside; }} public class DollViewer{ public static String show(Doll d) { /* code goes here */ } public static void main (String [] args) { Doll dolls1 =…
- java Finish the method called countAppearance() that will take String [] and String arguments and return an int for the number of times the given String word is found in the given String [] arr.

Revise the Player class so that its user can make individual rolls of the dice and view the results after each roll. The Player class no longer accumulates a list of rolls, but saves the string representation of each roll after it is made. Add new methods rollDice, getNumberOfRolls, isWinner, and isLoser to the Player class. The last three methods allow the user to obtain the number of rolls and to determine whether there is a winner or a loser. The last two methods are associated with new Boolean instance variables (winner and loser respectively). Two other instance variables track the number of rolls and the string representation of the most recent roll (rollsCount and roll). Another instance variable (atStartup) tracks whether or not the first roll has occurred. At instantiation, the roll, rollsCount, atStartup, winner, and loser variables are set to their appropriate…
