Reading Multiple Nested Variables From XML
Aug 19, 2014
I have an XML document that have multiple levels of nesting:
<virtue name="Innocence">
<rank ranklvl="1">
<stat type="Physical Mitigation" value="84" />
<stat type="Resistance Rating" value="89" />
<stat type="Tactical Mitigation" value="29" />
</rank>
<rank ranklvl="2">
[Code] ....
I need to return all the different values within each child element... i.e.
Virtue: Innocence
Rank: 1
Physical Mitigation = 84
Physical Rating = 89
Tactical Mitigation = 29
Virtue: Innocence
Rank: 2
Physical Mitigation = 162
Physical Rating = 175
Tactical Mitigation = 54
I can read the XML okay but I get an error on displaying the information.
for (int temp = 0; temp < nList.getLength(); temp++) {
//Node nNode = nList.item(temp);
Node nNode = nList.item(temp);
//System.out.println("
Current Virtue :" + nNode.getNodeName());
[Code] ....

for (int i = 0; i < 4; i++)
{
for (int k = 0; k < i; k++)
{
System.out.print(" ");
}
for (int j = 4; j > i; j--)
{
System.out.print("$");
}
System.out.println();
}
I was told that the answer when this code segment is printed look's like this:
$$$$
$$$
$$
$
Here's what I did:Looking at the outer for loop, (i) 0 < 4 so I went into the first inner nested loop. (k) 0 is not less than (i) 0 so I went to the 2nd inner nested loop and found that it worked, and I was able to repeat this loop 3 more times and then I exited the loop and printed the line out (giving me the first line of four $). I then went back to the outer for loop, increased i by 1 and (i) 1 < 4 so I went to the 1st inner nested loop. I used the 0 for the k first and (k) 0 < 1 so I printed out a space (now here's where I get lost) I then incremented k by 1, so k = 1, but 1 is not less than 1 (i) and so I moved on to the next nested for loop. So when this line is printed, I'll only have one space when there should be 4.

I just started playing around with Java for awhile, but got caught up in a problem when using ArrayList.
CinemaAppMain
public class CinemaAppMain {
public static void main(String[] args) {
new CinemaApp().start();
[Code]....
I am trying to get the movie name and theatre title from their ArrayList, and I know I need to go through the movie list & theatre list to find their name & title, and compare it with the user input and print out the result.
I use for(int i=0;i<movies.size();i++) to go through the the movie list, and I tried using for(int i=0;i<theatres.size();i++) to go through the theatre list. But when I printing multiple time with different user input value, it will show me strange result (screening have same movie name & theatre name, the else if statement is printed below the user input, user input is printed more than once after the first time).
Edit: I know its wrong for me to use nested for loop,if not, another solution is needed to get the item inside both of the list. (getting the "title" from movie list & "name" from theatre list)

So here is my code:
while (key != 3) {
if (key == 2) {
System.out.println("Input from a file");
// System.out.print("Enter file name: ");
// String str = expression.nextLine();
int i = 0;
File file = new File(
[code]....
What I need to happen is the file gets read in, the file is in the form:
a * ( b + c ) / 2 + ( 8 * b )
a = 5
b = 10
c = 20
( x + y ) * z
x = 13
y = 21
z = 3
And so on. My code is supposed to start at the beginning and have output like:
Infix: a * b ( b + c ) / 2 + ( 8 * b )
variable values:
a = 5
b = 10
c = 20
**It then needs to store the variable names along with their values in a hash table**
postfix: a b c + * 2 / 8 b * +
value: 155
And it continues reading the file in the same fashion.
My issue is I am not properly extracting the variables and their values from the file. I have the variables in an array list actually, so I have those, but don't know how to efficiently navigate to the values, then store the character and value in a hash table, while protecting against possible blank lines within the file. Thus just calling nextLine()s and next()s wouldn't work to get to values because they would lead to an error.

Now that I have figured out how to return a single variable from a method I am on to the next step, I need to return 2 or 3 variables from a method. I have searched the internet on how to do this to no avail (am I doing the wrong search? I do not know) but what I need to do is return a second (and eventually a third variable)
Here is what I have
private static String Engine() {
String engine = "";
int enginePrice = 0;
System.out.println("Choose a engine size:");
System.out.println("[4] cylinder");
[Code] .....
Which does not work.

I have a multi scene JavaFX FXML application [URL] ....
I have added a TextField to Scene2.fxml and Scene3.fxml files each scene has its own Controller Class with a ScreensController class that loads a HashMap with Id name, Node screen that is defined in the ScreensFramework
class (Main class)
public void addScreen(String name, Node screen) {screens.put(name, screen);}
So each time you click a Button on a screen (scene) you fire an ActionEvent and move to another screen
myController.setScreen(ScreensFramework.screen2ID);
What I would like to do if it is possible is use the value in the TextField on Sceen2 and transfer it to the TextField on Scene3. I have discovered that unless both FXML files are loaded this is so far not possible. This is a desktop application. So how do you create a variable that is GLOBAL and has a life after one class is unloaded or one FXML file is unloaded?
At this point I do not want a database to accomplish this task.I have developed in Visual Basic 6 where I would just declare a global variable that could be used through out the application.

I want to read json file as follow;
{
"M": {
"row": [
{
"col1": "c00"
},
{
"col1": "c10",
"col2": "c11"
},
{
"col1": "c20",
"col2": "c21",
"col3": "c22"
}
]
}
}
Next to reading I need to assign to two dimensional array, but without giving "col1","col2","col3" a lot.
The array is for example, Array[3][] = {{"c00"},{"c10","c11"},{"c20","c21","c22"}};

Lets say I have a desire to convert and entered value to Centigrade or Fahrenheit and that I have two Radio Buttons to designate the type of conversion with the Answer posted to a TextField on Scene Two from a button click event on Scene One ok Now I would like to convert the value in the TextField on Scene Two to Kelvin and reflect the value on Scene Three in a TextField by clicking a button on Scene Two
lets say I have 4 FXML files sceneONE sceneTWO and scenMain and I created 4 controllers ControllerONE and MasterController
So far I can navigate to the different scens with just the MasterController code below...
BUT because I have two FXML files I can not capture the value in the first FXML file and pass it to the second scene
This project is my attempt to adapt the FXML style code from this web site
Switching to Different Screens in JavaFX and FXML | JavaFXTutorials
Which uses this code to switch scenes
//get reference to the button's stage stage=(Stage) btnS1.getScene().getWindow();
//load up OTHER FXML document
root = FXMLLoader.load(getClass().getResource("ATTwo.fxml"));
But will not permit variable transfer due to scope of variables which reside in two different FXML files
public class MasterController implements Initializable{@FXML public Button btnS1;
@FXML public Button btnS2;
@FXML public Label lblS1;
@FXML public Label lblS2;
@FXML public TextField txfS1;
@FXML public TextField txfS2;
@FXML public AnchorPane root;

I'm very new to Java, and I am creating a program that takes multiple user input to create one face. I have a class for the eyes, nose, lips, and headshape. For some reason, my program is not drawing the graphics. ***for question purposes, I have only included my head shape class and my test class****
my "test" class:
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
public class FaceTest
{
public static void main(String[] args)
{
String head = JOptionPane.showInputDialog("Would you like a circle, square, rectangle shaped head?: ");

I am in the process of creating a calculator GUI that calculates different answers based on inputs two main comboboxes and numbers in the appropriate textfields. The first one allows the user to choose from 18 different materials, while the second has the user choose between two different shapes. In a brief word explanation, here's how it's set up:
User chooses material.
User chooses shape.
User types in appropriate values.
'Calculate' button clicked.
If shape = rectangle, execute rectangle calculation.
Else if shape = cylinder, execute cylinder calculation.
Everything works just fine with zero errors on all 18 materials and all kinds of decimal numbers when the second shape is selected. So the math and layout is solid. However, when the first shape is selected, it returns a $0.00 answer regardless of the input values (still no red-line errors). In efforts to troubleshoot, when I have /* Cylinder section */, the rectangle section works to a 'T'. This, I believe is caused by poor formatting in the syntax of the 'if' 'else if' in regards to the shape combobox.
//If 'Rectangle' is selected:
if(shapeDropDown.getSelectedIndex()==1) {
//6061
if(materialDropDown.getSelectedIndex()==0) {
String msg0 = "The price is: $"
+ currencyFormat.format((0.098*(number2*number3*number4)*3.06));
totalPrice.setText(msg0);

just trying to learn it on my spare time and I'm doing do-while loops
public class help {
public static void main (String args[])
throws java.io.IOException {
char choice, ignore;
do{
System.out.println ("Choose one:");
System.out.println("1. if");
System.out.println("2.switch");
[code]....
It makes no difference in the program wither i delete this block or keep it..how while (choice < '1'| choice >'2'); translates? I would assume it would be while (choice >= '1'| choice =<'2');?

Question: you are only allowed to use numbers from 1-6. Write a program to find all the permutations when three numbers are multiplied together to give a result 8. one number cannot occur twice in any permutation.
public class number4
{ public static void main(String[] args)
{
for(int a=1; a<=4; a++)
{
for(int b=1; b<=4; b++)
{
[Code]...
my program also prints out 2 2 2. but i'm not allowed to do that. how can I stop it from printing 2 2 2 ?

how a nested for loop increments the outer loop and then the inner loop and then when it runs the inside code.I've ran the program a few times but I'm just not understanding it, need little narrative to it?
for(int i=0; i < 5; i++){
System.out.println("i - " + i);
for(int j=0; j < i; j++){
System.out.println("j - " + j);
count++;
}

Here's what "Why doesn't this work?" question. It concerns a small method which is part of a card game.
I'm trying to check a condition from a section of an array, without a predetermined number of times any given call to this method will require a check. How much of the array I'm checking could vary greatly.
Is it at all possible to nest a for loop yielding a variable number of boolean && conditions inside an if? Am I just missing the right bracketing or is this nesting (if that's the word) even possible in the language?
To clarify, below is broken code. Compiler isn't letting me accomplish this goal as I envision it.
public boolean isFlanking() {
boolean f;
int reach = Math.abs(selectorX - targetX);
if(rival.getDeck()[selectorX].getPile().isEmpty() == true &&

int count = 0;
for (int x = 0; x < 3; x++)
for (int y = x; y < 3; y++)
for (int z = y; z < 3; z++)count++;
What is the value of count after the code segment is executed?
The answer is 9, but I don't really understand how this answer was derived.

I want to ask a user his name. If he writes John, then program should answer "John is your first name." Is he writes Smith, the program should say "Smith is your last name." If user writes anything else, such as Sue, the program should state "This is not your name."
How to ask user input and also how to work with the nested if-else statement. For some reason I do not understand, my code always results in "This is not your name" even if user writes John or Smith.
import java.util.*;
public class NestedIfElse{
public static void main(String args[]) {

Is there any advantage to using Java's operations defined in sets or collections over inspecting in nested for-loops?
For example, suppose I want to keep items from one array that do not appear in another, I could do:
for( PrimitiveType prim_1 : someArray ){
for( PrimitiveType prim_2 : otherArray ){
if( prim_1 != prim_2){
///put in some return list
}
}
}
Or else I could do:
ArrayList<NotPrimitive> excludedElements =
new ArrayList(Arrays.asList(primitiveArrayToExclude));
for( PrimitiveType elem : someArray){
if( ! excludedElements.contains( elem ) {
//put in some return list
}
}
I personally see no improvement in legibility nor any reduction of error potential.....
