Assign Values To Nodes Read From XML Using Java?
Apr 13, 2014i 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.
Coding AI Game Through Java
Apr 10, 2015The game has two players: x and o. The players take alternate turns, with player x moving first at the beginning of each game.
Player x starts at position (1,1) while o starts at (8,8).
Each turn, a player can move like a queen in chess (in any of the eight directions) as long as her path does not cross a square already filled in or occupied. After moving, the space vacated by the player is designated as filled and cannot be moved to again. Notice that only the space that was occupied is filled, not the entire path.
The game ends when one player can no longer move, leaving the other player as the winner.
The coordinate (1 1) indicates the top left hand side of the board.
The board is specified as a list of rows. Each row is a list of entries:
- is an empty square * is a filled in square x is the current position of the x player o is the current position of the o player
The board will always be 8 by 8.
Your player function should take in the parameters as described above and return a move as a list in the format (row column) within 1 minute. If you cannot move, return (nil nil). The Tournament Referees will check for this. If you return an illegal move, the other player (and the Tournament Referees) will detect it and you will lose.
Additionally if your time expires you will lose.

View Replies View RelatedJava Coding For Constructors And Input
Oct 25, 2014I was required to make a program that contains 3 data fields, 2 constructors, and 4 methods. I'm having a hell of a time trying to put some input into this, where the user would choose from 1 of the 3 data fields I made up for car prices and choose their vehicle. As far as the constructors go, I made a default one but I'm not sure on how to A) implement another constructor and how do I involve the input into this and C) where the methods go in that.
I'm thinking of putting the input first but that ruins my constructors? I realize I asked a lot, but this is an online class without a text, and I'm basically starving for knowledge. [code]

How To Use While Loop To Read Values
Apr 21, 2014So I'm trying to write a program that takes in 20 numbers and computes their average and I'm supposed to use a while loop to read the values and to make sure that all the numbers are positive. My while loop is set up and does all the math correctly but I have completely forgotten how to taken 20 numbers from the user all at once and then run them through the while loop.
HERE IS MY CODE SO FAR:
public static void main(String[] args) {
int num = 100;
int count = 0;
int total = 0;
while (num >= 0 && count < 20){
if (num %2 == 0){
total += num;
count++;
}
}
double avg = total/20;
System.out.println("The Result Is: " + avg);
}

I/O - Read 11 Values From A Text File / Each Value On Separate Line
Mar 26, 2014So I'm trying to read 11 values from a text file, each value on a separate line. The first value I use as loop control to run through calculations on the other ten and finally output both the numbers and the calculations to the console and an output file. I'm not getting a compiler error or a runtime error but my loop seems to stop after reading the first line. It also doesnt seem to be writing to my output file but does create it when I run the program. This is what my text file looks like
10
150.4
88.4
-3.14
499.4
799.4
1299.8
0
1900.2
901.7
4444.4
This is what my program looks like
import java.util.*;
import java.io.*;
public class assignment7scratch
{
Toolkit_General toolKit = new Toolkit_General();
public static void main (String[]args)throws IOException
[Code] .....
so I dont get an error but this is what my output looks like
----jGRASP exec: java assignment7scratch
This program reads a list of values representing number of miles driven by individuals. It will output the dollar amount their rental cars cost.
Number of miles traveled on the left as well as amount reimbursed on the right

----jGRASP: operation complete.
it also doesn't write anything to my output file, though it does create one.

Program That Read Sequence Of Input Values And Display Bar Chart
Oct 21, 2014Write a program that reads a sequence of input values and displays a bar chart of the values, using asterisks, like this:
********************** **************************************** **************************** ************************** **************
You may assume that all values are positive. First figure out the maximum value. That value's bar should be drawn with 40 asterisks. Shorter bars should use proportionally fewer asterisks.
import java.util.Scanner;
import java.util.ArrayList;
import java.util.Arrays;
public class Array717

public static void main( String[] args )

The problem is that all this code does is print 1 line of *'s and what seems to be thousands of them

View Replies View RelatedCoding Own Classes - If Condition?
Jun 9, 2014public int getIndexOfAMonster(String nameToGet){

1.What does the if-condition do?If the name of a monster in the array is equal to the name stored in the variable, return the monster's assigned value.
2.What does the for loop do? The loop condition simply loops through the whole arraylists. (In other words, it simply checks each Monster contained in the lists).
3.Assuming that the driver code compiles, explain what it’s use is? If the name of the monster is the same as the variable passed unto this method, return the number assigned to that Monster.
Eclipse - Coding Multiple If / Else Statements
Apr 22, 2015What I am attempting to program is a simple Boss battle. I would like the user to have 2 options (for now): Run, or Attack. I got the portion completed and working, but once I tried to implement the Run feature (the way that it's supposed to work is you can either attack OR run), both Attack and Run will happen. Also, for some reason, the running always fails (it will always return the else statement, then move onto the attack.) Here's my code:
import java.util.*;
public class AdvancedBossBattle {
public static void main (String[] args) {
Scanner scan = new Scanner (System.in);
Random gen = new Random();
int bosshp, bossdmg, playerhp, playerdmg, runChance;

Sieve Coding Not Pairing In Output
Apr 1, 2015When I compile the code, it goes through fine in the compiler. However after entering the boundaries for the lower an upper it doesn't produce the prime pairs between the two boundaries that the user sets. I have tried changing some of my integers that i initialized no luck. I looked at the last section of public void showPrimes() . However I can't seem to see where it has gone wrong there. I have included the entire code, plus the section again that I think is wrong. I have also posted the final output of what it looks like and what else should be included to make it easier to see what I am missing. Basically it keeps giving me zero primes even when the boundary is 100 and 200, or so and so forth.
import java.util.Scanner;
public class kbeaudry_xSieve
{
public static void main (String args[]){
kbeaudry_xSieve i = new kbeaudry_xSieve();
}
boolean primes[] = new boolean [50001];
int upper;
int lower;
[code]....
This is what i get when I actually run the program. However in the section where I have added *****, this is where it should put the prime pairs in.
Please enter a lower boundary and an upper boundary and I will print all of the sexy prime pairs between those boundaries.
Please enter the lower boundary (between 1 and 50000): 200
Please enter the upper boundary (between 1 and 50000): 600
There were 0 sexy pairs displayed between 200 and 600.. I am still working on another code for my that I had issues with, however I had to go out of the country for a few days to take care of some work.

Coding Multiple-choice List Dialogs
May 15, 2014// create an AlertDialog Builder and set the dialog's title

// replace _ with space in region names for display purposes
String[] displayNames = new String[regionNames.length];
for (int i = 0; i < regionNames.length; ++i)

From the code above, An alertdialog would pop up prompting the user to select a region (from a list). the user will then be allowed to select multiple choices accordingly. If I choose to select anything, the app crashes. How to mitigate this problem?
I know that I have to use a conditional check like if (isChecked){}; but I don't know how to do it. I want it to pop up a dialog box when none is checked prompting them that they should select atleast one.

Game Coding - No Enclosing Instance Of Type Background Is Accessible
Dec 11, 2014So I'm fairly new to java and have been learning game development. I've come across this error message on my StartingClass.java coding. Here is the Coding
@Override
public void start() {
bg1 = new Background(0,0); // This line is giving me the error!!!!!!!!!!!
bg2 = new Background(2160, 0);
hb = new Heliboy(340, 360);
hb2 = new Heliboy(700, 360);
robot = new Robot();
Thread thread = new Thread(this);
thread.start();
The error reads "No enclosing instance of type BackGround is accessible. Must qualify the allocation with an enclosing instance of type BackGround (e.g. x.new A() where x is an instance of BackGround)." Now I have seven classes in my in my games src folder and none of them but the StartingClass.java has the error. Once again I'm fairly new to java and have not benn able to fix it.
These are the classes{
BackGround.java
Enemy.java
Heliboy.java
package-info.java
Projectile.java
