Compare Two Files And Count New Edges For Each Node And Their Total

Jan 28, 2015

How can I do this: program to compare two files that which has data like node id: which it is connected to. like 3: 5 7 12 5: 7 14 9 etc. so this type of content is there in both the files. I need to compare these two files and count new edges for each node and also total new edges.

How can I do this? I tried and learnt taking files as input and read the normal text content.

This is what I tried :

/*

* To change this template file, choose Tools | Templates
* and open the template in the editor.

package comparetwofiles;
import java.io.*;

How To Get Total Number Of Pennies In Dollar Amount For The Output Of Total Pay

Mar 28, 2014

I cannot get the right output for my program. I need to get the total number of pennies in dollar amount for the output of Total Pay. This is my program. The directions are:

Write a program that calculates the amount a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies. Do not accept a number less than 1 for the number of days worked.

import java.util.Scanner;
import java.text.DecimalFormat;
public class PenniesForPay {
public static void main(String[] args) {
int numDays;

[Code] ....

totalSalary should be total number of pennies / 100....However its not picking up only day 30 of pennies which is 536,870,912 pennies and then dividing it?

Calculate Total Price And Display Total In Order Class

Oct 11, 2014

I'm struggling with inheritance in my assignment. The assignment states that I should use the calculatePrice() to calculate the total price and use another method to display the total. The I must overload the calculatePrice() and add a fee in the SpeedOrder() class.

My main class

package useorder;
import javax.swing.*;
public class UseOrder {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Order.display();

[Code] .....

The problem is mainly displaying the TotalPrice field and. I can't display TotalPrice if it's not static but if it's static I can't inherit it to the SpeedOrder class to assign the total in the overloaded calculateprice method. How can I display the total in my order class and use it in my SpeedOrder class?

Image Print In Poor Quality With Jagged Edges

Apr 14, 2014

I'm trying to print (to the printer) a small image 265x35 px and it is printed in very poor quality with jagged edges. When I'm printing it from any other program (e.g. Word, mspaint, etc) it is printed clearly.

Also, the image is printed bigger than it's normal size (approximately 25%). But, I'm not doing any scale in my code. I did scaled it down to the right size, but the quality still remained very poor and jadged.

The image is a transparent PNG file. I tried with a BMP too, but I got the same results.

I'm using

Graphics g;
g.drawImage(headerLogo, x, y, headerLogo.getWidth(), headerLogo.getHeight(), imageObserver);

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]]++;

Deleting A Node From A BST

Oct 23, 2014

I am having an issue deleting a node for a tree for one of the cases.The cases for deleting a node are:

1. if its the root set it to null
2. if its a leaf, have its parent point to null
3. if the node you want to delete does not have a right child, have deleted nodes parent point to delted nodes only child
4. find the nodes predecessor(next largest value), have have predecessor's left child be deletes left, and preds right to be deletes right. then have deletes parent point to pred and finally, delete preds old spot (the one that is giving me an issue, I believe)

The pre order of the tree I am currently on is 50 5 4 10 190 100 100 200 190 201

or------------------50
-------------5--------------190
---------4------10-----100-------200
--------------------100---190--201

I am trying to delete 190 (which should be the first one)but when I try to print out the list after I delete, I get a stack overflow error when I try printing everything out.I am pretty sure that it has something to do with me hooking up the nodes incorrectly since error occurs for case 4, since it prints out just fine when I deleted previous nodes (like a leaf).Here is my delete method: (note, ignore my determineX and checkOtherHalf methods)

public boolean delete (E item) {
if(root == null){
return false;

else if(item == root){
root = null;
return true;

[code]....

I have confirmed that it is a pointer issue: I need to assign replacements old parents left child to null, to stop it, but idk how.Here is a screen shot of it when I debug it

How To Attach External Files To Executable Jar Or Exe Files

Apr 13, 2015

In a program I created, I'm using a text file that contains some texts needed for the program. The method relevant to this is something like the following.

private String wordgen(){
try {
BufferedReader reader = new BufferedReader(new FileReader("src/Resources/adjectives.txt"));
Random rand = new Random();
int low = rand.nextInt(400);
String fil="";
int i=0;
while(i!=low){

[Code]...

The program runs fine in netbeans project but once the jar is created it does not corporate with the text file. ("null" is returned) How can I attach text files to jar and exe?

How To Advance To Next Node In Linked List

* Otherwise, the new element is the element immediately after the original current element.

cursor = cursor.getLink();

Setting Left And Right Node Values

May 6, 2014

I am getting errors when I try setting left and right values (which are String types) for my tree.I tried doing something like:

Node node = new Node("Is it human?", null, null);
node.getLeft().setNode("Is it Zelda?");//the first left Q
node.getRight().setNode("Is it Kirby?");//the first right Q

but that gives me a runtime error of "java.lang.NullPointerException" which points to the line 2. I also tried this:

Node node = new Node("Is it human?", null, null);
node.setLeft(setNode("Is it Zelda?"));//the first left Q
node.setRight(setNode("Is it Kirby?"));//the first right Q

but that gives me another error, pointing to the setNode for both lines 2 and 3,plus it wouldnt make sense since both setLeft and setRight takes in Node types, not String types.

Here is my Node class:

public class Node {
private Node leftPt, rightPt;//left and right pointers for Node
private String node, left, right;
public Node(String node, Node leftPt, Node rightPt){
this.node = node;
this.leftPt = leftPt;
this.rightPt = rightPt;

Swing/AWT/SWT :: Manually Select A Node In JTree?

Oct 24, 2014

I have problem with manually (through my java code) selecting items in a JTree. I did Google the problem and found solutions here :

[URL]

This code worked for me only partially. Once I tried selecting deeper nested nodes, I ran into problems. Since my production code is very cluttered I built an example and reproduced my exact problem in it.

DummyView.java
package de.fortis.tcws.client.controller;
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

[code].....

The important method is 'manualSelect(String[])'.

It streps through the tree by comparing user objects and finds the target node. Then it calls 'navigateToNode()' which uses the solution discussed in the links above.

This method behaves incosistently:

If you call it with an empty array it will correctly select the root node. The righthand pane shows the text of the selected node. = correct

If you call it with target node 1 it will correctly select node 1. The righthand pane shows the text of the selected node. = correct

If you call it with target node 1.1 it will select node 1.1 but for some reason it is not displayed as marked (no background). The righthand pane shows the text of the selected node. = only partly correct

If you call it with target node A it will run into an exception. Debugging reveals that the selection occurs correclty at first. You can also observe the righthand pane showing that 'A' was selected. But afterwards another TreeselectionEvent is occuring that has a NewLeadSelectionPath of null. I do not know where this second SelectionEvent is triggered from.

This code is run with Java 1.6.0_39 which is also what I will have to use in production.

Find Node Method Within Binary Tree

Mar 29, 2015

I have some work where I have to create a binary tree. Anyway I am stuck on one of the classes which has several methods I must fill in! The code is below

The headers for each method are: public Node find (member p1)The method find(Member p1) is used to return the node which contains a particular member. It is a private method because the interface to CabinetTree should not provide direct access to the internal nodes. It makes use of the method Node findNode (Member p1, Node current)

and the next method is : Node findNode(Member p1, Node current) which searches the tree from current node to find a node whose value is equal to the Member p1, i.e. a node in the tree such that p1.equals(current.getMember()) is true. If there is no such node then the method should return null.

public class CabinetTree {
private Node head;
CabinetTree(Member p1) {
head = new Node(p1, null);

Display More Information When Node Is Clicked In Jtree?

Aug 27, 2014

I'm new to java and I'm currently trying to make a program that uses a JTree that implements a properties file. I have the Keys set to the nodes but I want it so that when the node is clicked it will retrieve the keys value from the prop file.

I did have some code for this initially but I as it did not work at the time and was causing issues to my project I got rid of it. I have my code for the jtree,the listener and the prop file.

Tree

Java Code:

JPanel panel_1 = new JPanel();
panel_1.setBackground(Color.WHITE);
panel_1.setSize(new Dimension(22, 0));
scrollPane.setViewportView(panel_1);
Properties properties = new Properties();

[Code] ....

Java Code: add = Adds files changes in your working directory to your index. Example: git add .

rm = Removes files from your index and your working directory so they will not be tracked.

Example: git rm filename mh_sh_highlight_all('java');

Is there a way of doing this? Been trying for a while now but to no prevail. The image is what it currently looks like

JavaFX 2.0 :: TreeView Position Of Node Handle

Jun 2, 2014

I want to ask if there is an option to set the vertical position of the node handles of the TreeView-control.
 
I used a custom TreeCell factory with icons of sizes between 24 and 64 pixel and the location of the handle is regardless of the size of the icon on top of the cell. So if you got large icons the view did not look so nice.What I want is a property or something to center the handle in the cell depending on the size of the cell. Is there such an option?

JavaFX 2.0 :: Mouse Event For Tree Node

                    // Some action
                }
            }
        });

For some reason when I click on a tab body I can also perform the listener action. How I can add additional statement to perform the action only if I select node?
