Nov 8, 2014I'm currently working on a project which requires to have text displayed along a curve. If found this entry a good starting point. It works fine for me on my develompment machine, however the customer on his machine noticed some issues.
The basic idea is to define a path for the text, explode the text into the separate characters and animate them along the path the fraction of the character of the whole lenght. So with a animation duration of 10 seconds and a label of ten characters, the first character would be animated along 1 second, the second 2, and so forth.
This is done by jumping to the designated time in the animation, start the animation and stop it immediately.
Now the problem as I see it, for stopping the animation a separate timer is used, so it can happen that at the time the animation is actually stopped, the animation moved further than the first frame. The effect is that the last characters of the text appear in front (wrapped around).
As I have no evidence to prove or disprove my theory, what do you think is this plausable? I can see a workaround for this issue by defining a path for each character and then let the animation run to the end. While I can set the duration of the animation to 1 ms which should not be visible to the human eye, I'm not able to make the characters invisible and turn the visiblity on when the animation finishes, they always become visible at the start.
Or create my own animation/transition for placing the characters.

In And Out Degree Of A Graph
May 2, 2014I have this code for reading a text file and printing out information about the graph, the program works perfectly but I need to figure out the in degree and out degree of the graph if it is an directed graph. So my question is how would I go about implementing that? I know what in degree and out degree does but in terms of the code I'm not so sure, so I'm thinking if the case of vertex 0,1 the first vertex comes before the second vertex so that would in an in degree right? But how would I do that?

Generate Bar Graph From Data
May 22, 2014I need to generate a bar chart given the data that is in main. The relative performance of each sorting algorithm with respect to time, number of comparisons, and number of swaps for each data set (e.g., 50,000 –400,000 random integers). Each algorithm will have 5 bars corresponding to the 5 data sets. The height of these bars will depend on the performance of the algorithm for that data set.
I know how to write a bar with normal values like integers but for this I'm not sure because the values for instance comparisons and swaps are not given they are calculated. I just need to know what steps to go about doing that, you can even express them in pseudocode or even just explaining it I don't need the code, I think. Here is the main
public class Main {
public static void main(String[] args){
int t= 50000;
int t2=100000;
int t3=200000;
int t4=300000;

Adjacency List Graph
May 4, 2014I'm trying to read a text file of a graph and print information about the graph including the order and size of the graph, rather it is a directed or undirected graph, if it is directed the in and out degree, and the and a list of all vertices for which it is adjacent. The problem is the adjacency list is just printing out the list of vertices instead of the adjacency list. Is there something in my code that is problematic? Also I'm unsure of how to go about the in and out degree

Each Bar In Graph Will Represent Value Of Each Element Of Array
Nov 5, 2014So I have an array which holds 19 elements, each element represents a value of 'income'. I'm trying to code the graph so that each bar will represent the value of each element of the array (income). I have been given the code ' for (int Bar = 0; Bar < array of values.length; bar++);' however i'm unsure if this is how to do it, or what to add to this code to make it work.

Reading A Text File For A Graph?
May 2, 2014I'm trying to print the number of vertices in a text file on a graph which is the first integer in the file and then the type of graph is an undirected graph for a 0 or a 1 for a directed graph. Right now I'm just trying to print the number of vertices which is a 6 in the text file.
Here's the text file:
6,1
0,2 0,4 1,4 1,5 2,1 2,3 2,5 3,2 3,4 4,1 4,5 5,1 5,3 5,2
Im getting the following error:

at java.util.ArrayList.add(Unknown Source)
at Vertices.main(Vertices.java:21)
Then I need to know how to go about reading the next line in the file, do you read it with the nextLine and put it into an arrayList or do I read each index in the graph?
public class Vertices

public static void main(String[] args) throws Exception

// Read the number of vertices
String line = inFile.nextLine();

View Replies View RelatedDisplaying A Graph From Data In File
Oct 12, 2010A graph consists of vertices and edges that connect vertices. Write a program that reads a graph from a file and displays it on a panel. The first line in the file contains a number that indicates the number of vertices (n). The vertices are labeled as 0, 1, ..., n-1. Each subsequent line, with the format u x y v1, v2, ..., describes that the vertex u is located at position (x, y) with edges (u, v1), (u, v2), etc. Your program prompts the user to enter the name of the file, reads data from the file, and displays the graph on a panel.
Example File:
6
0 30 30 1 2
1 90 30 0 3
2 30 90 0 3 4
3 90 90 1 2 4 5
4 30 150 2 3 5
5 90 150 3 4
Analysis:
A graph is a mathematical structure with vertices and edges that connect the vertices. A graph is a very useful tool for modeling real-world problems. This project is to display the graph. The information for the graph is stored in a file. The number of the vertices n is stored in the first line of the file. The vertices are labeled 0, 1, 2, ..., n-1. The format of each subsequent line is u x y v1, v2, ..., which describes vertex u at location (x, y) and u is connected to vertices v1, v2, etc.
Design:
The program should first read the information about the graph from a file. The program prompts the user to enter the file name and read vertices location information into a two-dimensional array named position, where (position[0][0], position[0][1]) is the x- and y-coordinates for vertex 0. For example, in the sample graph, (position[0][0], position[0][1]) is (30, 30). The program reads the edge information into an array of ArrayList named edge (ArrayList is covered in Chapter 11). For example, in the sample graph, edge[0].Is an ArrayList that contains elements 1 and 2, which indicates that vertex 0 is connected to vertex 1 and vertex 2. position and edge should be created as followed:
int[][] position = new int[n][2];
ArrayList[] edge = new ArrayList[n];
I don't know how to implement the code. I have started but I am not sure how to proceed.

Directed Graph Cycle Detection
Jan 4, 2015I have some problem checking if a directed graph has a cycle or not. So I have a given rooted directed graph, and find if there at least one existing cycle.
For example, I have to input the Root Node, followed by a number of nodes, the nodes in the graph, number of edges, and the adjacency list representing the edges. Each entry in the adjacency list contains a pair of nodes. The ordering of the nodes in the pair represents the direction of the edge. An entry A, B means that there is an edge from A to B. Nodes in each pair is separated by a space. One input per line.
And the output should display whether the directed graph has a cycle or not.
Sample input:
A //Root Node
6 //Number of Nodes
A //Nodes in Graph
B
C
D
E
F
6 //Number of edges
A B //Adjacency list representing the edges
B C
C D
C F
F E
E B
Output:
Cycle!
Graph Representation:
Based on the illustration above, the graph has one cycle. The cycle exists in nodes B, C, F and E.

Is it thread-safe, when the getter-Method just return the value like the example show? Or must I create a Runnable, so stage.getTitle() is called inside the Java Application Thread? How I return the value then?
Drawing A Graph Based On Stock Values From 2 ArrayLists?
Apr 19, 2015[URL] I made a program that takes 2 stock values by URL tickers, and now I need it to draw a graph with the values for the 2 stocks, so they can be compared visually. So far my idea was to create 2 arraylists that consist of the values for each stock, so that I can draw the graph so that x always move with 1 step, and y0 is the first coordinate, and y1 is the second, and after that y1 is the first, y2 second etc.
