- Java Overview In this task, you should try using the Scanner class to read data from the keyboard. This data should be stored in variables in your program and then printed on screen. Task You should write a class called Story that should include a main method. This programs should create a fairy tale for a child. The program is based on a completed story, but some words must be replaced with such as the user may enter. The fairy tale you are going to based on are the following: The little ant (1) There was once a small, small ant that lived with its (2) and its (3) siblings in an anthill, by a large (4) in the forest. The little ant is called (1). For the most part, (1) and his siblings used to work on carrying (5) and (6) to the stack, but today it was (7), so (1) was free. The words that are crossed out are the words that your program should ask the user for. In total, there are seven entries the user must make. The program must save these entries in separate variables and then…Course Title: Modern Programming Language Please Java Language Code Question : Create a Java Project With Your name as “MJibranAKramProjectQNo1”, add a class to this Project, Class name should be MJibranAkram with 18Arid2891 as “MJibranAkram18Arid2891” (a) Add a Method to Accept names and marks of n students from user, enter the value of n from User(b) Ensure that valid data is entered. If user enters an invalid data, then appropriate message should be displayed using Message Dialog Box e.g. ‘Name cannot be a number’ or ‘Marks must be an integer value’ (c) Add another Method, to Display this data in descending order according to marks such that name of student having maximum marks should come at the top and the name of student having minimum marks should come at the bottom.It is possible to invoke a method without explicitly providing an argument into a parameter when a(n)__________ is given for it.
- Instructions The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly. An example of the program is shown below: Enter name Juan Hello, Juan! Task 1: The DebugThree3 class compiles without error. Task 2: The getName() method accepts user input for a name and returns the name value as a String. Task 3: The displayGreeting() method displays a personalized greeting. Task 4: The DebugThree3 program accepts user input and displays the correct output.Retail StoreSuppose you have been consulted by a retail shop around your area to build a simple calculator. The calculator must be able to perform arithmetic operations (+, -, *, /) on integers. The program receives an expression from the user. The expression is structured as follows: integer input followed by an operator and another integer input from user prior to displaying the final result. Write a Java application that can perform the above expression. Create a method that takes two parameters and performs an arithmetic operation on the passed values. Your final output should consist of the expression and the result.Programmers commonly use a technique known as __________ to break down an algorithm into methods. a. prototyping b. method modeling c. algorithm division d. top–down design
- Microsoft Visual C#, 7th edition. chapter 11, Programming exercise 11-3 Instructions: Write the program FindSquareRoot that finds the square root of a user’s input value. The Math class contains a static method named Sqrt() that accepts a double and returns the parameter’s square root. If the user’s entry cannot be converted to a double, display an appropriate message, and set the square root value to 0. Otherwise, test the input number’s value. If it is negative, throw a new ApplicationException to which you pass the message “Number can’t be negative.” and again set sqrt to 0. If the input value is a double and not negative, pass it to the Math.Sqrt() method, and display the returned value. An example of the program is shown below: Enter a number 9 Square root is 3 or Enter a number -9 Error: Number can't be negative. Square root is 0python Cylinder class: Instance variables: Make instance variables appropriately to accomplish the tasks you need. Methods: ?_init_ :: constructor, initializes instance variables o Additional Parameters: diameter and height (in that order) o Assumption: diameter and height will always be numbers which represent measurements in millimeters o Temporary Assumption (we will fix this later): diameter will never be negative and height wilI always be positive number above o ? get_volume : returns the volume of the cylinder based on its height o Additional Parameters: No additional parameters (just self). .0 Note: Use pi from the math module ?_str__ :: returns string representation with this format: "Cylinder (radius: 20.25mm, thickness: 6.10mm, volume: 7858.32mm^3)" o Additional Parameters: No additional parameters. o Notes: ? The quotes in the example are just our string boundaries! The first character in the above example is C. ? This method reports the radius (NOT the diameter). ? All…Kinetic energy is the measure of the work that an object does by virtue of its motion. It is best illustrated by the formula: KE = 0.5 mv² Create a java class that will call a method that will compute for the kinetic energy. Sample output: Enter mass of an object: 54 Enter velocity of an object: 2.87 The kinetic energy of an object is: 222.40 joules Note: 1. The result should be in 2 decimal places. 2. Apply the exception handling method. 3. SCREENSHOTS NOT ALLOWED! 4. Save your file as KineticPT.java.
