a.the length and width, in inches, of the paper.

View Replies View RelatedCount Number Of Books In Arraylist?
Jan 29, 2015We have been given an assignment to create a small library, with the following classes Library, Book, Author and Copy. With a given class Biblio which has predefined code and adds the books to the class book in an arraylist in Class Copy.
The UML Domain is attached so you know the flow of the classes Everything is working fine and the generated output is correct.
There is just one method in class Library that is not working, the int method has to count the number of Copy's based on the Class Book (String):
I have to go through the Arraylist in Class Copy and look for a specific book and return the number of copy's.
I have tried multiple steps using a for loop Now I have found a similar post the uses hashset, I have tried below code but the return comes back with 0. (There are 3 copy's)

Count Number Of Digits After Decimal Point?
Jul 21, 2014Given a Numbers instance, whose fields are arrays of all the built-in Java numeric types (int, long, float, double, big-decimal, etc), write a method to sort all the numbers into a master list, and then print out the numbers where the number of digits past the decimal point is equal to the index of the number in the master list.
Is there a function in Java that will give me just the numbers after the decimal? I tried Decimalformat but couldn't get it to work. Here is what I have so far; however, I think I might be on the wrong track.
public class Numbers
{
public static void main(String[] args) {
Byte bNum = new Byte((byte) -50);
Integer iNum = new Integer(168);
Long lNum = new Long(100000L);
Short sNum = new Short((short) 10000);
Float fNum = new Float(12.19f);
Double dNum = new Double(23.123);
BigDecimal bd = new BigDecimal("3.14159265358979323846");

How To Count Frequency Each Number In Array Occurs
Dec 14, 2014I'm trying to write a program that counts the number of times each number in an array occurs. In theory I understand how it work, you take the first element in the array, compare it again the rest of the array and any time it occurs in the array you increment a counter by 1. Then move onto the next element A[1] and so on...
This is what I've done so far :
public static void main(String[] args) {
int[] array = {5,6,2,5,2,2,0,1,6};
int count = 0;
for(int i = 0; i <array.length; i++) {
int val = array[i];
for(int j = i+1; j<array.length; j++)
[Code] .....
I think I'm on the right track as it correctly prints out the frequency of the first 3 elements, but I'm definitely going wrong somewhere as it just doesn't do it right after that!

Count And Display Number Of Times Specified Character Appears In String
Mar 7, 2014Write a program using a while-loop (and a for-loop) that asks the user to enter a string, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the string. (So, you will have two separate program codes, one using a while-loop and the other one using a for-loop.)
Example:
Enter a string: "Hello, JAVA is my favorite programming language."
Enter a character: e
The number of times the specified character appears in the string: 3
I don't even know where to begin I've only got this
import java.util.Scanner;
public class letterCounter {
public static void main(String [] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a string");
String myString = sc.nextLine();
System.out.println("Enter a letter");
String letter = sc.nextLine();
}
}
Count Number Of Mouse Clicks User Is Inputting Into BlankArea
Jan 22, 2015IDE: BlueJ
I'm creating a small program to count the number of mouse clicks the user is inputting into a BlankArea for a school assignment. I just finished with making the program look nice and all so I was putting in a MouseListener to detect the clicks. However, when I tried adding a MouseListener to the code, the error in the title appeared.
Java Code:
import javax.swing.*;
import java.awt.*;
import javax.swing.border.*;
import java.awt.event.*;
public class CountClick
{
JTextArea textArea = new JTextArea();
[Code] ....
Here's what's going on:
Compiling causes error as described in Title Java Code: createAndShowGUI() mh_sh_highlight_all('java');
cannot be referenced from a static context appears Java Code: public static void main(String [] args) mh_sh_highlight_all('java');
It contains the thread safe and program previously launched without mouse functionality(program appeared when there were no MouseListener components and thread safe had all static method stuff).

JSF :: Count Number Of Views Created In A Session While Using Managed Bean With View Scope
Jan 30, 2014I am trying to restrict the number of views in JSF 2.0.2 using
<context-param>
<param-name>org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION</param-name>
<param-value>5</param-value>
</context-param>
In my case my managed bean is View Scoped and it supports a UI page which has multiple forms and each form is submitted as AJAX POST request.
As per the statndard, setting restriction to 5 should create 5 views and after that based on LRU algorithm the oldest views should get deleted if 6th views is created.
Therefore any action on the oldest view will throw the ViewExpiredException and i simply redirect the user to view expired page.
1) When i set the restriction to 5 views, i open 4 tabs with 3 forms each.
2) I submit the 3 forms on first tab everything works fine.
3) As soon as I go to 2nd tab and submit the first form thr, i get view expired exception
4) It seems I am exceeding the number of views I mentioned in web.xml
I want to know :
1) Does every AJAX POST submit itself creates a view ?
2) How I can count the number of views created in a session ?
3)Can i force expiry of a view in JSF 2.0.2 while the session is still alive ?
4) Normally JSF 2.0.2 session cachces the views. Lets assume session is alive the entire day but a view was created in morning at 9:00 AM and is not used again the entire day. Assuming that session doesn't reaches the max number of views it can save in entire day, will the view created in morning expire on its own after certain interval of time ? If not , can we still force its expiry while keeping the session alive ?
Using Count Element Method To Count Occurrence Of Characters In Array
Jun 30, 2014I have an array with the following characters {'E', 'L','E','P','H','A','N','T','P','O'}
now, I need an array that will store the first array such that only the occurence occurs e.g {'E','L','P','H','A','N','T','O'} Notice that the characters 'E' and 'P' occur twice and as a result were not repeated the second time in the new array.
How would one go about this using the counting elements technique?
I tried this but not sure how to use the counting elements technique.
char [] arr = new char{'E', 'L','E','P','H','A','N','T','P','O'};
char[] bucket = new char[(arr[0] * arr.length)];
for (int i = 0; i < len; i++)
bucket[arr[i]]++;
How To Get Specified Width Of Integer Printed Output
Jul 21, 2014If I code:

I believe I'll get: 0,1,999 but I want 0000,0001,0999 i.e. a width of 4 for small integers.
Changing Output - Each Row Printed Out On Single Line

User To Select Item From Printed Out Array List
Jun 24, 2014I am trying to have a user select from a printed out array list, instead of having the user type in the "bill type" each time there is a bill to avoid user error as much as possible. For example I would like to have it print out like this:
"Select bill type from list:
1. Rent
2. Car
3. etc..."
and I would like the user to choose a number and not type in the "bill type". I don't want to use "Switch case" because it would need to be an expanding and I don't think "switch case" can do that.
Here is the code:
package homebudget;
class Spending
{
//Do i need a totalAmount variable?
String type;
double amount;
int year, month, day;
public Spending()
[Code] ....
case 2:
//Give option to enter a new expense or pick from list.
//How to do this? If Statement that doesn't list duplicates, or a while search?
resp = JOptionPane.showInputDialog("Enter the type of expense:");
type = resp;
resp = JOptionPane.showInputDialog("Enter the amount of the expense:");
amount = Double.parseDouble(resp);
[Code] .....
