Question
Assignment: Enhancing Dice Roll Stats Calculator
Introduction:
The project involves creating a program to roll pairs of dice, gathering statistics on the outcomes. Probability differs in the roll of two dice compared to a single die due to varied combinations.
Dice Roll Series:
- User greeted with "Welcome to the Dice Roll Stats Calculator!" and prompted to specify rolls.
- Java classes: DiceRoller, Indicator, Validator.
- DiceRoller:
- Arrays: rollSeries (captures results), statIndicators (stores statistical indicators).
- Constructor rolls dice as per user request.
- Methods collect stats and print the report.
- Indicator class:
- Contains dicePairTotal and dicePairCount.
Displaying Results:
- Sort statIndicators array before display.
- Indicator objects sortable by dicePairCount (implements Comparable).
- Example output:
-----------------------
dice
pair roll
total count percent
---- ------ --------
7 5 50%
10 2 20%
4 2 20%
2 1 10%
Tasks:
- Exclude combinations with zero roll counts.
- Add a descriptive report header.
- Calculate and display the percentage of roll counts within the series.

Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…arrow_forwardJAVA:arrow_forward

Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.arrow_forward

The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845 4520125 7895122 8777541 8451277 13028508080152 4562555 5552012 5050552 7825877 12502551005231 6545231 3852085 7576651 7881200 4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.arrow_forwardJAVA PROGRAM Chapter 7. PC #1.
