Imagine you are developing software for De Anza College that requires uses to enter their password. Software requires that the password be encrypted using the following criteria: 1. All letters are converted to a number of your choice. 2. All numbers are converted to an alphabet 3. All punctuation characters are converted to 0. Write a class that takes a password input and meets the state criteria. Demonstrate the program that allows the user to enter a password and then display the encrypted message for testing purposes.

Create a program that will count the number of numeric characters in an input string. The program should be able to ask the user for the input string and should be able to display the number of numeric characters on the screen. For this exercise, you should create your class to handle the different operations. Remember that any input/output operations should be done in the main method while all calculations should be done inside the class. Remember that you need to apply encapsulation in your class. Sample Output: Enter a string: Hello 123 Number of numeric characters: 3
Create a class CharacterClassStringClass. Ask the user to type 'y' for yes or 'n' for no.Read the input as String and test if the user type Y\y or N\n which are OK we display the message (you typed ' ' thank you!)If the user enters any other character except y,Y, N, n display the message (you typed ' ' incorrect character!If the user enters numeric input display the message (you typed ' ' incorrect and numeric!)If the user enters a string whose length is greater than 1 we display the message (you typed more than 1 character ' ' incorrect length)
Consider a Java class that you could use to get an acceptable integer value from the user. An object of this class will have the attributes • Minimum accepted value • Maximum accepted value • Prompt string and the following method: • getValue displays the prompt and reads a value using the class Scanner. If the value read is not within the allowed range, the method should display an error message and ask the user for a new value, repeating these actions until an acceptable value is entered. The method then returns the value read. a. Write preconditions and postconditions for the method getValue. b. Implement the class in Java.
To use any of the prewritten classes besides those in the java.lang package, you must___ a. use the entire path with the class name b. import the class c. import the package of which the class you are using is a part d. use any of these methods
6. Use JOptionPane class to show the messages and let user enter the data in the dialog box for this exercise. You need to calculate average score by a game for a team. Ask the user a team name, then number of games played, then total points in all games. Then calculate average score by game, and show to the user.
Task 5: ScanningMoney.java Write a program that reads User Input using the Scanner class. Your program should ask the user how many quarters, nickels, dimes, and pennies they have, then display the total amount in dollars. This can be done in main method. Expected Output The highlighted text denotes text that you type into the console yourself. It is not printed by the program. Due to floating point values being used your answer may have the trailing 1 or not. ----JGRASP exec: java ScanningMoney Quarters: 4 Dimes: 3 Nickels: 2 Pennies: 1 You have $1.4100000000000001 ----JGRASP: operation complete.
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 a radius for a circle >> 7 The radius is 7 The diameter is 14 The area is 153.93791 Task 1: The DebugPen class compiles without error. This task is dependent on completing task #2. Task 2: The DebugCircle class methods work without errors. Task 3: The DebugFour1 class compiles without error. Task 4: The DebugFour1 program accepts user input and displays the correct output.
The program should implement a class. Write a program that reserves a room in a hotel. The hotel menu should be able to perform the following. 1. Reserve a room The program should ask the user to enter a number of guests to occupy the room. Change the status of the room to reflect the number of guests that just checked in. Display the information about the room in a nice format.
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 print…
Write a program that takes a decimal value between 1 and 10 and displays its equivalent Roman numeral value. Display an error message ifthe value entered is outside of the acceptable range. Write a two classsolution. The second class should allow the user to input a test value.
Create a Java program that will display the student's information. The program should perform the folowing: • Ask the first name, middle initial and last name of the student. • Prompt the user to select between old student and new student by pressing either O (old student) or N (new student). • If O is pressed, ask the student to enter the following grades per term: o Prelim o Midterm o Prefinals o Finals Compute the final grade of the student by using given formula: FG (Prelim* 20%) + (Midterm 20%) + (Prefinals 20") + (Finals 40%)). Display the full name of the student with his/her accumulated grade using the format given. If N is pressed, ask the student to enter his/her average grade then display the full name grade. Grade Format: o 1.00 99-100 o 1.25 = 96 -98 o 1.50 93-95 o 1.75 90- 92 o 2.00 = 87 -89 o 2.25 84-86 o 2.50 = 81-83 o 2.75 76-80 o 3.00 75 o 5.00 Below 75 If an invalid letter is pressed, display an error message. %3D
Create a Java class that accepts a number The input number must be between 10 and 99. You must validate this. If the input number is outside of this range, output a message "Invalid Input" and exit the program. If its a valid number: Check if the square of the sum of its digits is equal to the input number If the square of the sum of its digits is not equal to the input number, find the reverse of the number and display it. For example: Input: 81 Output: 81 because 81 = (8 + 1)2 Input: 23 Output: 32 because 23 is not equal to (2 + 3)2
