Count Number Of Books In Arraylist?

Jan 29, 2015

We 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)

package domein;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;
import domein.Boek;
import domein.Exemplaar;

Count Number Of Digits After Decimal Point?

Jul 21, 2014

Given 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, 2014

I'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 Number Of Occurrences Of A String In Array List?

Apr 6, 2015

I am trying to count the number of occurrences of a string in an array list. I used the following code:

int count = Collections.frequency(strings, search);

strings is the name of the array list and search is the string that I am trying to count the number of occurrences of. My program compiles correctly, but when I enter the string to search for, I get the following error: "Exception in thread "main" java.lang.NullPointerException at java.util.Collections.frquency(Collections.java:37 18)

Why am I getting this error message and how do I fix it?

Count Number Of 7s (User Input) - Illegal Start Of Expression

Oct 15, 2014

I'm attempting to create a program that employs a method to count the number of 7s a user puts as an input into the program. I'm just getting started, but I'm getting an error when I try to implement a main method that says "Illegal start of expression"

What adjustments could I make to eliminate this error message?

// Add a main method here.
public static void main(String[] args) {
//Error occurs here
public static int countSevens(int n) {
// 0. Clean-up. Get rid of any minus signs as that is not a digit.
n = Math.abs(n);

Count And Display Number Of Times Specified Character Appears In String

Mar 7, 2014

Write 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, 2015

IDE: 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).

Coin Classes - Count Number Of Times Head And Tail Appear

I am trying to flip a coin 1000 times and make the driver class count the number of times a head and tails appear. However, I am having some trouble trying to figure out the error:

package Week5;
import java.util.Random;
public class Coin {
private int heads;
private int tails;
private int face;

[Code] ....

I was able to print out the generated numbers, but java will print either heads or tails a thousand times and count that as 1000 and nil for the other probability...

JSF :: Count Number Of Views Created In A Session While Using Managed Bean With View Scope

Jan 30, 2014

I 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 ?

JSF :: Submit Text That Will Be Displayed In List Of Paragraphs

Nov 17, 2014

I'm new to JSF and I'm facing a problem with displaying German umlauts correctly.

I have built a site that uses an inputText to submit text that will be displayed in a list of paragraphs (as simple html... <li><p>text</p></li> etc.). A managed bean is used as a controller to store data in backend and to retrieve it from backend for display. In backend the data is stored in a list of strings and using annotations this data is written to respectively read from file system on shutdown/startup via serialization. Sometimes when I'm sending German umlauts from my webbrowser they're not displayed correctly, other times however they are which is pretty weird to me.

I've built the project with NetBeans 8 and I made sure that under Properties -> Sources the Encoding is set to UTF-8. In the xhtml page for display the encoding is set as follwed:

<?xml version="1.0" encoding="UTF-8"?> //first line
<meta http-equiv="content-type" content="text/html; charset=utf-8"/> //in the head
<h:form [...] acceptcharset="UTF-8"> //all forms surrounding the inputText and the paragaraph list

I'm developing on a Ubuntu 14.04 desktop. For deployment I transfer the .war file via ssh to my server which is Ubuntu server (currently not sure which version, might be 12) and there I deploy the .war file on my Glassfish server online.

An example of how the input appears when it's incorrectly displayed: ä

The same letter appears like this when it's correctly displayed: ä

Another example, incorrect: ö

correct: ö

Once the data is input its appearance won't change anymore so I assume the incorrect encoding happens already before the data is stored in backend. I'm not sure yet under which conditions the data is displayed incorrectly.

Using Count Element Method To Count Occurrence Of Characters In Array

Jun 30, 2014

I 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]]++;

Displaying Two Document From One If Function

Oct 15, 2014

So I have this

function checkvalue (val) {
if(val==='replaced')
document.getElementById('check1h').style.display='block';
else if (val==='checked')
document.getElementById('check1h').style.display='none';
else
document.getElementById('check1h').style.display='none';
}

Which works fine... But if I try and add another document under the if VAL === replaced then nothing works and neither of the boxes appear.

function checkvalue (val) {
if(val==='replaced')
document.getElementById('check1h').style.display='block';
document.getElementById('check1n').style.display='block';
else if (val==='checked')
document.getElementById('check1h').style.display='none';
else
document.getElementById('check1h').style.display='none';
}

Is this not possible?

Also, Both of my input type are set up like this...

<input type='text' style='display:none' name='check1n' id='check1n' placeholder='Name of Part' />
<br>
<input type='text' style='display:none' name ='check1h' id='check1h' placeholder='Part Number' />
