JSF :: Submit Text That Will Be Displayed In List Of Paragraphs
Nov 17, 2014I'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.
Counting Number Of Steps Throughout The Circle
Jan 27, 2015The method public static int steps(int posts, int stride) calculates how many strides can be taken to get back to posts. Let's say if the method is (12, 4), it takes only three steps. Now let's say the method has parameters (12,5), so it should be (5, 10, 3, 8, 1, 6, 11, 4, 9, 2, 7, 12). My method works for such examplse as (12, 4) or (12,3) or (6,2)... but how can I figure out (12,5)?
Java Code:
public static int steps(int posts, int stride) {
int countSteps = 0;
int result = 0;
do {
result += stride;

Counting Number Of Words From User Input
Jan 2, 2015I tried the following code, OK:
Java Code:
String temp = "hi this sf hello is new what is this";
String[] cmd = temp.split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');
However, when i get the input from user , i didnt get the expected result:
Java Code:
System.out.println("Enter the input string to count the words: ");
String[] cmd = new Scanner(System.in).next().trim().split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');
Now Result for above code:
Enter the string to count the words:
hi this is new
words are: 1
Counting Number Of Bits For Char Representation?
Mar 14, 2014i need to show that there are 16 bits for a char variable.
i tried converting it to an int and then apply the bitCount method but that gave an output of 3.
what method should i use?
Sorting Arrays And Counting Number Of Swaps
Nov 2, 2013I need to modify modules used in the book that run a bubble sort, selection sort, and insertion sort on an integer array such that each module keeps a count of the number of swaps it makes.
How do I code for this?
Then we have to design an application that uses 3 identical arrays of at least 20 integers. That calls each module on a different array, and display the number swaps made by each algorithm.
Counting The Frequency Of Numbers Inside A Text File
Apr 7, 2014I have a source code here that counts the frequency of alphabetic characters and non-alphabetic characters (see the source code below).
import java.io.*;
public class letterfrequency {
public static void main (String [] args) throws IOException {
File file1 = new File ("letternumberfrequency.txt");
BufferedReader in = new BufferedReader (new FileReader (file1));
[Code] ....
But, let's just say that now I have the following characters in the text file, "letternumberfrequency.txt":
71 geese - 83 cars - 58 cows- 64 mooses- 100 ants- 69 bangles- 90 molehills - 87 noses
The numbers inside that text file would be considered as strings, am I right? But I want to extract the numbers so that I can also be able to count their frequency - not as individual digits but as whole numbers (that is how many "71", "83", "58", "64", etc. are there...). Would using "Double.parseDouble ()" work?

Read Picture And Print Out Number Of Blocks - Counting In Multidimensional Array
Dec 19, 2014I have to write a program that will read a picture and then print out the number of blocks inside it.
I have to read the picture as a binary matrix of the size r - c (number of rows times number of columns). The blocks are groups of one or more adjacent elements with the value 1.
- Blocks are built exclusively of elements with value 1
- Each element with value 1 is a part of some block
- Adjacent elements with value 1 belong to the same molecule.
We only take into account the horizontal and vertical adjacency but not diagonal.
INPUT:
In the first line of the input we have the integers r and c, separated with one space.
Then we have the r lines, where each contains s 0's and 1's.
The numbers inside the individual lines are NOT separated by spaces.
The OUTPUT only print the number of blocks in the picture.
Example:
INPUT:
7 5
01000
00010
00000
10000
01000
00001
00100
OUTPUT:
6
THIS IS WHAT I CAME UP SO FAR:
import java.util.Scanner;
class Blocks{
public static void main(String[] args){
Scanner sc=new Scanner(System.in);
char ch[][];
int rowNum=sc.nextInt();
int columnNum=sc.nextInt();

Counting Using Custom Scale
Aug 6, 2014I'm having trouble creating a highly efficient algorithm for counting within a custom scale. This problem applies to futures trading, specifically treasuries contracts.
One specific treasury contract has 32 units before rolling over to the next whole number. So, the price scale looks something like this ...
1 0
1 1
1 2
...
1 29
1 30
1 31
2 0
2 1
...
2 30
2 31
3 0
...
If I pick a number (price) at random, let's say 1 28, and I want to add 8 units to that value, I should end up with 2 4. I can do this using brute force, calculating remainders, etc, etc....
Counting Duplicates In A Stack
Apr 11, 2014Write a method compressDuplicates that accepts a stack of integers as a parameter and that replaces each sequence of duplicates with a pair of values: a count of the number of duplicates, followed by the actual duplicated number. For example, suppose a variable called s stores the following sequence of values:
bottom [2, 2, 2, 2, 2, -5, -5, 3, 3, 3, 3, 4, 4, 1, 0, 17, 17] top
If we make the call of compressDuplicates(s);, after the call s should store the following values:
bottom [5, 2, 2, -5, 4, 3, 2, 4, 1, 1, 1, 0, 2, 17] top
This new stack indicates that the original had 5 occurrences of 2 at the bottom of the stack followed by 2 occurrences of -5 followed by 4 occurrences of 3, and so on. This process works best when there are many duplicates in a row. For example, if the stack instead had stored:
bottom [10, 20, 10, 20, 20, 10] top
Then the resulting stack after the call ends up being longer than the original:
bottom [1, 10, 1, 20, 1, 10, 2, 20, 1, 10] top
If the stack is empty, your method should not change it. You may use one queue as auxiliary storage to solve this problem. You may not use any other auxiliary data structures to solve this problem, although you can have as many simple variables as you like. You may not use recursion to solve this problem. For full credit your code must run in O(n) time where n is the number of elements of the original stack.
I wrote a code but still having a problem with it , am I allowed to use 3 while loops ?
public void compressDuplicates(Stack<Integer> s ){
Stack<Integer> backup= new Stack<Integer>();
int count = 1;
while(!s.isEmpty()){
int temp = s.pop();
[Code] .....
// example 1
Expected output : bottom [5, 2, 2, -5, 4, 3, 2, 4, 1, 1, 1, 0, 2, 17] top
My output: //bottom [17, 2, 2, 2, 2, 2, -5, -5, 3, 3, 3, 3, 4, 4, 1, 0, 17, 17] top
Counting Duplicates In Array
Jan 23, 2013It's supposed to count all of the duplicates in an array and print out how many occurrences of the value starting at whatever index, or if there are no duplicates state that. Basically:
No duplicates with value 1 beyond Index 0
There are 3 more occurrences of value 2 starting at index 1
There are 2 more occurrences of value 2 starting at index 2....
This is what I've got so far:
Java Code:
public static void main(String[] args) {
int[] arr = {1, 2, 2, 3, 4, 2, 4, 3, 0, 5, 3, 2};
for(int i = 0; i<arr.length; i++){
int count = 0;
for(int j = i+1; j<arr.length; j++){
if((arr[j] == arr[i]) && (i!=j)){
count++;
System.out.print("There are " + count + " more occurrences of ");
System.out.println(arr[i] + " starting at index " + i);
}
}

Counting Cards GUI Interface
Dec 5, 2014I curious for tips for moving forward within my current code for my counting cards GUI interface. I need two labels one for the card deck, and the other for the randomized card face. When the card face shows, in the count value text field the value of the card is added. For each card this is to happen through until the whole deck. There is also a card count text field to count how many cards have been dealt out. Now with that being said, I am being held back by getting the two labels to show in my GUI, the buttons show, but I need getting the cards and its value to show and initialize, with the card count in the card count text field.

Queues - Reading And Counting
Jul 21, 2014Here's what I'm trying to do:
Complete the body of the following method. Use a CharQueue to store the input line as it is being read. The parameter is an EasyReader from Appendix B of the text. Use the method in.charInput( ) to read and return the next character of the EasyReader, and use in.isEOLN( ) to determine whether the next input character is the end-of-line.
public static int counter(EasyReader in)
// Precondition: There is a line of input waiting to be read from in.
// Postcondition: A line of input has been read from in, up to but not
// including the newline character. The return value of the method
// is the number of times that the LAST character of the line appeared
// somewhere in this line.
[EXAMPLE Input: ABBXDXXZX - The value returned by counter would be 4 for this input since there are 4 X's in the input line.]
***When I look at this I understand that I'm being asked to finish the method, that I have 1 input, which is an "EasyReader" object called in and that I use a CharQueue object along with the method isEOLN( ) to grab characters from in while looking for an end of line and then sticking the values in the queue and then I can go through the queue and figure out the number of times that last character shows up in the queue. I just am at a loss on the "how".
