Question

Assignment #2*: Build A Report Purpose: Exercise, use, Inputs, Outputs, and perform conditional evaluation Requirements: (Multiple classes/Multiple types of input) • Input: Report Owner’s full name and 7 numbers (at least one double and one integer) o The owner’s name cannot contain any special characters, blank spaces, or numbers • You must use an if statement and at least one switch statement in your program • You are not allowed to have static variables or methods in any class except for the class with the main method. • You have to have at least 2 classes • You are not allowed to use ArrayLists or Vectors, only primitive arrays or string arrays if you want. Application Operation: 1.) Input, via a question in the console, the report owner’s first name as a string and build the last name via input, one character at a time. a. Check, conditionally, to make sure the first name and last name don’t contain any numeric characters, numbers between 0 – 9. If it does you must remove it. The names can not contain any white space either or special characters. 2.) Input report name via a request from the console. 3.) Input, and display, the total of the numeric input after each input is entered. Average the numeric input, indicate lowest numeric input value and the highest numeric input value for the previous numeric inputs, before the next numeric input is asked for. (Example given in class) 4.) Have a program exit input, condition, value available (i.e. if you type -1 the program exits) 5.) Create and display a final report that should have the report name, owner and the following: Numeric output should appear as a table with the following columns: (columns should be underlined) a. Input Number b. Highest Number c. Lowest Number d. Total (by the row) e. Average Number 6.) At the end of the report you must have a grand total for the numeric entries

Answer 1

import java.util.Scanner;

// Defines class Test

class Test

{

// To store first, last, report name

String fName, lName, reportName;

// To store total, average, height and lowest numbers

double total, average, highest, lowest;

// Scanner class object declared

// Default constructor to initialize data members

{

fName = lName = reportName = "";

}// End of default constructor

// Method to accept name

void acceptName(String message, int type)

{

// To store valid name

String validName = "";

// Displays message

System.out.print("\n Enter your " + message);

// Accepts name

String name = sc.next();

// Loops till end of the string

for(int c = 0; c < name.length(); c++)

{

// Extracts a character at c index position from string

char ch = name.charAt(c);

// Checks if the current character is a digit

if(Character.isDigit(ch))

;// Do nothing

// Otherwise add the character to valid name

else

validName += ch;

}// End of for loop

// Checks if the second parameter type is 1 (first name)

if(type == 1)

fName = validName;

// Checks if the second parameter type is 2 (last name)

else if(type == 2)

lName = validName;

// Otherwise the second parameter type is 3 (report name)

else

}// End of method

// Method to accept number

void acceptNumbers()

{

// Counter for number of numbers entered

int counter = 0;

// Loops till user enters -1

do

{

// Accepts a number

System.out.print("\n Enter a number (-1 to stop): ");

int no = sc.nextInt();

// Checks if user entered -1 then come out of loop

if(no == -1)

break;

// Otherwise

else

{

// Increase the counter by one

counter++;

// Checks if counter is 1

if(counter == 1)

// Assigns the number to both highest and lowest

highest = lowest = no;

// Otherwise not the first number

// Checks if number is greater than the earlier

// highest number

else if(no > highest)

// Assigns the number as the highest number

// Checks if number is less than the earlier

// lowest number

// Calculates total and average

// Displays message

System.out.print("\n Number: " + no +

"\n Highest: " + highest +

"\n Lowest: " + lowest +

"\n Total: " + total +

"\n Average: " + average);

}// End of else

}while(true); // End of do - while loop

}// End of method

}// End of class

// Driver class definition

public class ValidateTest

{

// main method definition

public static void main(String st[])

{

// Creates an object of class Test

Test t = new Test();

// Calls the method to accept first name

t.acceptName("first name.", 1);

// Calls the method to accept last name

t.acceptName("last name.", 2);

// Calls the method to accept report name

t.acceptName("report name.", 3);

// Displays names

System.out.println("\n First Name: " + t.fName +

"\n Last Name: " + t.lName +

"\n Report Name: " + t.reportName);

// Calls the method to accept numbers

t.acceptNumbers();

}// End of main method

}// End of driver class
