I have below xml file...
<?xml version="1.0" encoding="ISO-8859-1"?>
<T0020
xsi:schemaLocation="http://www.safersys.org/namespaces/T0020V1 T0020V1.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.safersys.org/namespaces/T0020V1">
<INTERFACE>
<NAME>SAFER</NAME>
[Code] ....
And I want to take this xml file and split it into multiple files through java code like this ...
File1.xml
<T0020>
<IRP_ACCOUNT> ..... </IRP_ACCOUNT>
<IRP_ACCOUNT> ..... </IRP_ACCOUNT>
</T0020>
File2.xml
<T0020>
<IRP_ACCOUNT> ..... </IRP_ACCOUNT>
<IRP_ACCOUNT> ..... </IRP_ACCOUNT>
</T0020>
so i have applied following xslt ...
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:t="http://www.safersys.org/namespaces/T0020V1" version="2.0">
<xsl:output method="xml" indent="yes" name="xml" />
<xsl:variable name="accounts" select="t:T0020/t:IRP_ACCOUNT" />
<xsl:variable name="size" select="10" />
[Code] ....
Now I want to apply this XSL to xml through Java Code...
TransformerFactory tFactory = TransformerFactory.newInstance();
Source xslSource = new StreamSource(xslFilePath);
Transformer trans = tFactory.newTransformer(xslSource);
trans.transform(new StreamSource(xmlFileName), new StreamResult( ????));
Here how can I map new StreamResult( ) input parameter with xsl Result document argument ??
Or Can you give me a link of Example which use result document and Java transform method to Output multiple document ??
Here new StreamResult take only 1 file as to be transformed ....

public void add(int d){
listNode l = new listNode (d, null);
l.next = first;
first= l;
}
public list Sum2List (list l1, list l2){
//variables
int sum;
[Code] .....
But I have a problem in my first listNode where it ll be pointing to null, thus in the sum2List method the program checks the while condition into false and doesn't go through the loop.

having trouble trying to understand the insertion and removal of Nodes.
I have to insert a new node at the end of the linked nodes, if i insert by terminal : 1, 2, 3. The printed nodes are going to be in the same order, 1,2, 3.
I have done the exercise, but it only prints the last node created and i dont know where its the problem. We did it before with "insert at the beginning", may be the problem is with the print() method in SimpleList.java, but i dont know how to print "backwards".
This is the code:
Node.java
public class Node {
public int infoNodo;
public Node next;
}
SimpleList.java
public class SimpleList {
private Node head;
[code]....

I have noticed that you can style JavaFX controls using their sub-structure.
E.g. to style the label in a table column header to be left justified I can do this :
.table-view .column-header-background .label { -fx-alignment: center-left ; }
How can I style my own nodes/controls doing this? Basically it amounts to asking how the selectors like ".column-header-background" are associated with sub-structures of my Java control/node objects. So suppose I have something like
.fancy-node .fred .label { ... }
How does JavaFX associate fancy-node and fred with something in my implementation of a Node/Control?

I had a question about data structures. For the insert method of a linked list, the 'node' object is declared in the insert method. So doesn't the 'node' get destroyed as soon as the closing brace of the insert method is encountered? How do all the nodes continue to occupy memory?

I am using an ArrayList to make a list of nodes. I cannot seem to find documentation on how to call the nodes, just find how to get int and strings from a list.

Is it possible to find the number of paths between two nodes in a directed graph using an adjacency matrix? I know how to find all said paths of a given length by using matrix exponentiation, but I don't know how to find all the paths. The professor didn't note it in the assignment but I assume she meant all simple paths because this is a cyclic graph, so there's a potentially infinite number of paths.
I'm thinking I should use matrix exponentiation to find the number of paths of lengths 1 to n-1, where n is the number of nodes in the graph. Then add the number of paths for each length together. Would this work?

i am trying to assign unique values to nodes read from XML file.. eg: consider this XML file:
<breakfast_menu>
<food>
<name>Belgian Waffles</name>
<price>$5.95</price>
<description> ...Strong Belgian waffles...</description>
<calories>650</calories>
[code]....
now assigning these nodes "a unique value" has to be done following the LSDX labelling pattern i.e:
To the document element we first give an “a”.As there is no parent node for the document element, we assign “0” at the front of that “a” . “0a” is the unique code for the document element (breakfast_menu). For the children nodes of “0a”, we continue with the next level of the XML tree which is “1” then the code of its parent node which is “a” and a concatenation “.” . We then add a letter “b” for the first child, letter “c” for the second child, “d” for the third child and so on.Unique codes for children nodes of “0a” shall be “1a.b”, “1a.c”, “1a.d”, etc.Hence foe the above given XML the mapping would look something like this:
0a breakfast_menu
1a.b food
2ab.b name
2ab.c price
2ab.d description
2ab.e calories
2ab.f chef
3abf.b chef1
3abf.c chef2
1a.c food
2ac.b name
2ac.c price
2ac.d description
2ac.e calories
2ac.f chef
3acf.b chef1
3acf.c chef2
For more samples about LSDX labelling : 1.) Section 3.1 LSDX Labelling on this link: [URL]
2.) Fig 3 on page 1189 on this link:[URL]
right now i am using SAX parser to read xml and get the nodes in their hierarchical order..now the problem is that i have to assign these specific value to their respective nodes using java.

What is better and easier approach for exchanging data (in my case list of objects) between servlets in different nodes in same cluster? I thought about RMI or just direct url servlet call. But it seems that I'm missing something here.
My problem is the following:
I have to create some kind of diagnostic storage for each cluster member. It will collect all information and errors during application work.
And If I need to check application status I do web request and it will show me that these servers (cluster members) are okay and that node has an issue.
I'm using spring and tomcat.

The task is
-getting words from dictionary text file and inserting them into a hash table - DONE
-getting words from a usertext file and inserting them into a red-black tree - STUCK
-after that i need to see if there is nodes of words that dosen't exist in the dictionary and print if so
kinda like a spelling checker
OK so the main code that hold the reading and storing part of dictionary and inserting to hash table

I am doing an assignment in my Java class and I need to connect the nodes to make a 12 pointed star. I have already drawn out the star and figured out which nodes to connect together. The only thing I cannot get is to show all of the nodes in the order they connect. I can only get the first 3 nodes to show up. I need it to wrap around and basically keep adding 5 to the last node until all numbers 0-11 are used.
public class StarWinding {
public static void main(String[] args) {
for (int i = 0 ; i < 12; i+=5) {
System.out.print(i + " ");
}
}
}
And the out put so far is: 0 5 10
I need it to be: 0 5 10 3 8 1 6 11 4 9 2 7

How could I read an XML document from the web? I've seen people use SAX or DOM methods, but I've unable to make them work due to lack of experience so I would need a pretty brief overview not just 2 bits of code without any imports etc.
Also how would I be able to COMPARE the information? Like if it's " Sunny " I set a label text sunny etc.?!

TL,DR: observe the nodes just below, that is the data each node in the link list contains. How do I iterate through the entire list to reach the last element (H), so I can add an element right after it?
So I have 4 nodes doubly linked with two dummy nodes for head and tail:
head
node1 = {A}
node2 = {null, B}
node3 = {C, null, D, E}
node4 = {null, F, null, G, null, null, H, null}
tail
Ok, so since the list only contains 8 elements that are not null, its size is actually 8 correct? So now lets say I have an add method that has
add(E item) and inserts the item at the end of the list. So I can get to the last node with tail.previous(), but then how do I iterate to the end so I can add the item after the last item in the list (H). I guess I don't know how you only access one nodes data when that data is an array with empty spaces.
Here is the entire Node code:
Also, I can't just iterate through the whole thing because I am not supposed to. I am supposed to just find the right node and iterate through that only.how to maneuver around a linked list containing nodes where each node contains an array.
/**
* Node class that makes up a DoublingList. Feel free to add methods /
* constructors / variables you might find useful in here.
*/
public class Node<E> {
/**
* The node that comes after this one in the list

I am trying to remove a character from string as below
public String reomveChar(String str, int n) {
if(0<=n & n<=(str.length()-1)){
//str.charAt(n)
char o=str.charAt(n);
return str.replace("o","");
//a.replace("o","");
}
return null;
}'
what is the best way to remove it.
If i call like
removeChar("hello", 1) i should see hllo.
When there are more than one way to do a challenge in java which one to choose as best way.
What is the criteria to decide one particular way of writing code is best among say 'n' different number of ways.

SO my current code creates a graph with vertices and weighted edges. This data is stored in a hashmap. The key of the hashmap is the vertex and the value is a second hashmap. This second hashmap contains the edges with the vertex it connected to as the key and the weight as the value. My current problem is that when i try to remove vertices they are removed from the key set but they stay in the value(the second hashmap) as the key for that hashmap. IS THERE A WAY TO REMOVE THE VERTEX FROM THE KEYSET OF THE SECOND HASHMAP.
Code is as follows
constructor{
adjacencyMap = new HashMap<V, HashMap<V, Integer>>();
dataMap = new HashSet<V>();
}
removal method{
if(dataMap.contains(vertex)){

Referring Code 1, the book says line 16 of the code removes the element "Three" but line 17 does not remove the element "Four" because of Statement 1. The question is does remove(Object o) method invoke the == or the equals method because statement 1 and 2 seem to be in conflict
Statement 1:
Two objects are equal if their object references point to the same object. (which is nothing but definition of ==)
Statement 2:
The author refers to Statement 1 and says "As mentioned earlier, the method remove compares the objects for equality before removing it from ArrayList by calling method equals."
Java Code:
import java.util.ArrayList;
public class DeleteElementsFromArrayList {
public static void main(String args[]) {
ArrayList<StringBuilder> myArrList = new ArrayList<>();
StringBuilder sb1 = new StringBuilder("One");

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' />
