- 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: 3JAVA Write an application to simulate the rolling of two dice. The application should use an object of class Random once to roll the first die and again to roll the second die. The sum of the two values should then be calculated. Each die can show an integer value from 1 to 6, so the sum of the values will vary from 2 to 12, with 7 being the most frequent sum, and 2 and 12 the least frequent.in java write a code.......Imagine a publishing company that markets both book and audio-cassette versions of its works. Create a class publication that stores the title and price of a publication. From this class derive two classes: i. book, which adds a page count and ii. tape, which adds a playing time in minutes. Each of these three classes should have set() and get() functions and a display() function to display its data. Write a main() program to test the book and tape class by creating instances of them, asking the user to fill in their data and then displaying the data with display().
- 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.

The two shapes should start on opposite ends of the screen and then move toward each other. When they meet in the middle of the screen, each shape reverses course and moves toward the edge of the screen. The two shapes keep oscillating and bouncing off of each other in the middle of the screen. The program terminates when the shapes meet each other in the middle for the tenth time.
- in Java Create a class GreekAlphabet. Write EXACTLY 2 lines of code which generate any of the 24 letters of the the Greek alphabet. The first line generates any small case Greek letter. The second line generates any capital Greek letter. The first small case letter is alpha 'α' and the last letter is omega 'ω'.The first capital letter is alpha 'Α' and the last letter is omega 'Ω'java Write a program that prompts the user to enter a point (x, y) and checks whether the point is within the rectangle centered at (0, 0) with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure. (Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.) Here are sample runs of the program: Sample 1: Enter a point with two coordinates: 2 2 Point (2.0, 2.0) is in the rectangle Sample 2: Enter a point with two coordinates: 6 4 Point (6.0, 4.0) is not in the rectangle Analysis: (Describe the problem including input and output in your own words.)

If the number is 3, then the computer has chosen scissors. Don’t display the computer’s choice yet. 5.2. The user enters his or her choice of “rock”, “paper”, or “scissors” at the keyboard. Gather this input using JOptionPane.showInputDialog(). 5.3. Display the computer’s choice. 5.4. A winner is selected according to the following rules: If one player chooses rock and the other player chooses scissors, then rock wins. Display something to the effect of: “Rock smashes the scissors.” If one player chooses scissors and the other player chooses paper, then scissors wins.
