Thanks for the question. Here is the completed code for this problem. Let me know if you have any doubts or if you need anything to change. Thank You !! ================================================================================================ public class PartiallyFilledArray { private double[] array; private int elementCount; public PartiallyFilledArray() { array = new double[1]; this.elementCount = 0; } public void add(double value) { if (elementCount == array.length) { double[] tempArray = new double[elementCount * 2]; for (int i = 0; i < elementCount; i++) tempArray[i] = array[i]; array = tempArray; } array[elementCount++] = value; } public int getNumberOfElements() { return elementCount; } public double getElement(int i) { if (0 <= i && i < elementCount) { return array[i]; } else { return -1; } } }

You will need to think about problem solving. There are several multi-step activities. Design, compile and run a single Java program, StringEx.java, to accomplish all of the following tasks. Add one part at a time and test before trying the next one. The program can just include a main method, or it is neater to split things into separate methods (all static void, with names like showLength, sentenceType, lastFirst1, lastFirst), and have main call all the ones you have written...
Need help with the UML for this code? Thank you. import java.util.Scanner; public class Assignment1Duong1895 { public static void header() { System.out.println("\tWelcome to St. Joseph's College"); } public static void main(String[] args) { Scanner input = new Scanner(System.in); int d; header(); System.out.println("Enter number of items to process"); d = input.nextInt(); ...
I need to create a code for this prompt: In this project we will build a generic UserInput class for getting keyboard input from the user. Implementation: The class UserInput is a 'Methods only' class, and all the methods should be declared static. Look at the TestScanner.java program at the bottom of this page that inputs a string, int and double. It shows you how to use Scanner class to get input from the keyboard. Write FOUR simple methods, one...
******** IN JAVA ********* I have a program that I need help debugging. This program should ask a user to input 3 dimensions of a rectangular block (length, width, and height), and then perform a volume and surface area calculation and display the results of both. It should only be done using local variables via methods and should have 4 methods: getInput, volBlock, saBlock, and display (should be void). I have most of it written here: import java.util.*; public class...
specs for ComputeAverage ComputeAverage Write a class called ComputeAverage what it does: asks the user to enter three double numbers (see examples below), it uses Scanner class to read from standard input each one of the doubles entered by the user. it then prints the average of the three numbers. Suggested steps: 1. prompt the user to enter each of the three doubles by printing. 2. read each of the three doubles using a Scanner. Remember you need to declare...
Finish the given ProcessFile.java program that prompts the user for a filename and reprompts if file doesn’t exist. You will process through the file skipping any text or real (double) numbers. You will print the max, min, sum, count, and average of the integers in the file. You will want to create test files that contain integers, doubles, and Strings. HINT: Use hasNextInt() method and while loop. You may also want to use Integer.MAX_VALUE and Integer.MIN_VALUE for the initialization of...
IT Java code In Lab 8, we are going to re-write Lab 3 and add code to validate user input. The Body Mass Index (BMI) is a calculation used to categorize whether a person’s weight is at a healthy level for a given height. The formula is as follows: bmi = kilograms / (meters2) where kilograms = person’s weight in kilograms, meters = person’s height in meters BMI is then categorized as follows: Classification BMI Range Underweight Less...
This is the assignment..... Write a class DataSet that stores a number of values of type double. Provide a constructor public DataSet(int maxNumberOfValues) and a method public void addValue(double value) that add a value provided there is still room. Provide methods to compute the sum, average, maximum and minimum value. This is what I have, its suppose to be using arrays also the double smallest = Double.MAX_VALUE; and double largest = Double.MIN_VALUE; are there so I don't need to create...
