- In Java Programming - Write a program that reads an integer, a list of words, and a character. The integer signifies how many words are in the list. The output of the program is every word in the list that contains the character at least once. Assume at least one word in the list will contain the given character. Assume that the list of words will always contain fewer than 20 words. Ex: If the input is: 4 hello zoo sleep drizzle z then the output is: zoo drizzle To achieve the above, first read the list into an array. Keep in mind that the character 'a' is not equal to the character 'A'.I need to write a java program to draw one of four recursively defined patterns.The patterns are in the attached picture. In each pattern a smaller square is drawn at each of the four corners of the next larger square. This pattern repeats again and again. It might repeat any number of times or levels. In the picture, the pattern is repeated four times or levels. If another level were asked for, then 192 very small squares would have to be drawn. The patterns differ in which squares are drawn on top of the others and thus may be hidden from view. The largest square, the one at level one, is drawn in the center of a square canvas and the length of its side is one half the length of the side of the canvas. The center of the next smaller square is always at the corner of the larger square. And the size of the next smaller square is determined by a fixed ratio R. If the smaller square has a side of length s and the next larger square has a side of length b, then R is the ratio b/s. In…Write a complete Java program that: Ask the user to enter his/her first and last name. Then the program should compare the two strings to find out which has the alphabetical precedence in the dictionary. Then, print the result of the comparison to show which string comes first in the dictionary. Keep in mind that your program should also test if the two strings are equals and print the result accordingly.
- I need help with creating a Java program described below: Pancake flipping. You have a stack of "n" pancakes of varying sizes on a griddle. Your goal is to rearrange the stack in order so that the largest pancake is on the bottom and the smallest one is on top. You are only permitted to flip the top k pancakes, thereby reversing their order. Devise a recursive scheme to arrange the pancakes in the proper order that uses at most 2– 3 flips. Write a program to demonstrate how it works.UOWD Library is asking you to write a Java program that manages all the items in the Library. The library has books, journals, and media (DVD for example). All items have a name, author(s), and year of publication. A journal also has a volume number, while a media has a type (audio/video/interactive). The user of your program should be able to add an item, delete an item, change information of an item, list all items in a specific category (book, journal, or media), and print all items (from all categories). A menu asks the user which operation s/he wants to perform. Important: make use of collections, inheritance, interfaces, and exception handling wherever appropriate.Java considers the String data type as non-primitive, because it contains a sequence of characters and hence there is a predefined class called String dedicated to String processing. The String class has a lot of functions and continues to grow. See https://www.tutorialspoint.com/java/java_strings.htm for more on strings. Your task is to then create a java program that when give a sentence will replace the first occurrence of NUST with Namibia University of Science and Technology. Sample run 1: --- Input ---Welcome to my NUST --- Expected output (text)---Welcome to my Namibia University of Science and Technology. Sample run 2: --- Input ---The nust is a great institution of high learning. --- Expected output (text)---The Namibia University of Science and Technology is a great institution of high learning. Sample run 3: --- Input ---The NuSt was renamed from Polytechnic Of Namibia under Act No. 7 of 2015. --- Expected output (text)---The Namibia University of Science and…

Then the final total is calculatedImplement a C++ program to develop a class Library. Library contains pile of books as array and each book comprises of ISBN, Name, Author Name, Publisher Name, Issue Date, Return Date. A library will contain more than 50 books. please also write comments
- write a java program that asks the user to select from a list of 4 appetizers( nachos, onion rings, mozzarella sticks, chicken wings) 4 entrees(steak, salmon, chicken, pasta) 4 beverages( soda, water, tea, beer), and 4 desserts(chocolate cake, ice cream, apple pie, cheesecake) each with a wait time, and then calculate the price to pay based on selection. (each item has a price)Write a Java program that would resemble a payroll system. An input window which will accept the employee number and the number of days of rendered work. A 2d-arraylist that contains the employee number and the rate per day is to be searched and used to compute for the gross salary. Gross salary is computed by multiplying the number of days of rendered work by rate per day of the particular employee. If the gross salary computed is greater than 100,000 the tax is 20% of the gross salary, otherwise, the tax is 10%. Deduct the tax from the gross salary to get the net pay. Display the employee number, gross salary, tax deduction, and the net pay in an output window. Design your own input/output windows. ( USE OOP CONCEPT AND JOPTION)Q1. Write a java program using recursion to find the power of a number x", where x is double and n is integer. (Hint: x"-1). Q2. Write a Java program to demonstrate autoboxing and unboxing of byte and short. (Hint:The conversion of primitive data type (for example, int) into its corresponding wrapper class(for example,Integer) is known as autoboxing and the reverse process is known as unboxing.) Q3. Write a java program to accept three strings, slas “java Programming" and s2 as "ADVANCE JAVA" s3 as "Programming concepts in Java" Find length of s3. Change sl to Upper case and s2 to Lower case. Q4. Write the class definition and draw the class diagram for the following: Class Name Bank Attributes: private: Bname, code public: Phone, city Methods public: manage, deposit, withdraw Q5. a) Write a java program to demonstrate the use of mutable objects to find the Perimeter of a rectangle using Point (10,4) .Perimeter = 2(length + breadth). b) What is the purpose of a garbage collector?
