Your test in the sub loop probably never yields true. Have you stepped through your code with the debugger?
|
|
|
|
|
ya i also observed it is not going inside the loop condition is not satisfied but i can solved it out is my logic wrong ?
|
|
|
|
|
Your logic does not make much sense. You read a line from the file, then you are trying to use a while loop to read another line of text and compare it with the string a. You should read a line and then test if it contains the character you are looking for. However, note that you cannot set different characters to different colours. You can only use a single colour for the entire label.

You need to show us where, in your program, the main method is.
|
|
|
|
|
import org.graphstream.graph.*;
import org.graphstream.graph.implementations.*;
import java.util.Iterator;
public class GraphExplore {
public static void main(String args[]) {
new GraphExplore();
}
public GraphExplore() {
Graph graph = new SingleGraph("tutorial 1");
graph.addAttribute("ui.stylesheet", styleSheet);
graph.setAutoCreate(true);
graph.setStrict(false);
graph.display();
graph.addEdge("AB", "A", "B");
graph.addEdge("BC", "B", "C");
graph.addEdge("CA", "C", "A");
graph.addEdge("AD", "A", "D");
graph.addEdge("DE", "D", "E");
graph.addEdge("DF", "D", "F");
graph.addEdge("EF", "E", "F");
for (Node node : graph) {
node.addAttribute("ui.label", node.getId());
}
explore(graph.getNode("A"));
}
public void explore(Node source) {
Iterator<? extends Node> k = source.getBreadthFirstIterator();
while (k.hasNext()) {
Node next = k.next();
next.setAttribute("ui.class", "marked");
sleep();
}
}
protected void sleep() {
try { Thread.sleep(1000); } catch (Exception e) {}
}
protected String styleSheet =
"node {" +
" fill-color: black;" +
"}" +
"node.marked {" +
" fill-color: red;" +
"}";
}

Strange, I cannot see anything wrong with your code. Are you sure that the compilation worked successfully and the class file exists in the directory where you are calling the java command from?
|
|
|
|
|
Since your main declaration looks correct, it most likely the compile was not successful.
Look in the directory where you are compiling. See if the file GraphExplore.class was created.
You will get that message if it is not being created as a result of an error. As a further experiment, try misspelling the name when you run it, you will see that it is the exact same error.

Hello all,
I'm a .net developer.
I have a project that I might get into.
The thing is, the servers are WebLogic.
I don't know a lot on this subject so I wanted to know if I can deploy my asp.NET application on that server (or what I have to do for that)
Thanks for any help
|
|
|
|
|
|
I know it's an ASP.NET application question but since it's also related to Java, I thought that here is also a relevant place to ask. But I'll try there.
