I am currently trying to build some programs using google's lanterna library, but I still can't find a method to remove single characters from a Terminal/Screen/Window object. Does such a method exist, at least for one those three?
View RepliesI'm just a java beginner. I've spent a lot of time installing and configuring software. I'm using Netbeans 7.3 on Windows 7, 64 bit. Recently, I downloaded opencsv from sourceforge.
With no previous experience adding libraries, I read a blog post on adding the library. I think that I then:
Start a new project.
Right click on libraries
Add jar/folder
Gave the temporary path to the .jar file
After, I read the blog post again, and realized I'd missed it. This time I did:
Right click library, Add library, Create library
However, I kept getting a message that the same library already existed. If I do the first process above, I will find the same library.
However, I see no way in Netbeans to remove it. I've deleted the test projects. And started a new one. But the library now exists for all projects it seems.
I've grepped all the files under the Netbean directory, searching for "opencsv", but found nothing. The only things in the Windows registry were locations of files.
How can I delete this library permanently from Netbeans? Short of, uninstall, then reinstall? Is there a way to list all the libraries that Netbeans has?
I was trying to create a java program which can remove the repeated characters in a String. For ex-
Input: kamehamehaaa
Output: kameh
Here is my code:-
import java.util.Scanner;
class replace {
public static void main (String args[]) {
Scanner br = new Scanner(System.in);
System.out.println("Enter a word");
[Code] ....
On executing the program, StringOutOfBoundsIndex error occurs.
I see you can import in 2 ways:
import java.util.*;
or
import java.util.Scanner/Random/etc;
if I used the first one it imports all the librarys within that (directory?). If so would that add to a bigger file size?

View Replies View RelatedMy perfect idea is to have a Hashmap that would increase size each Key & value added, it's almost like a self-increasing array. I mean I could just create a very large Hashmap for me to add objects to anytime I want with a key to be able to find the object. Is this the most efficient way, because I'm trying to make my Object Library compatible with any amount of Objects, however, I know there's a limit to how many values you can have in an array, but it's larger than I'll ever need.
Let's say I'm making a number storage program, and I may need from 3 to 8 numbers to be stored with a key to find them easily using a Hashmap, rarely I may need below 3 or above 8. So is it efficient for me to create a Hashmap that has 10 placeholders? Or can I make this more efficient. Note, my Library is static.
I have written a library in one project but cannot seem import to import it into my main project whenever I try Maven says it cant find it though it is installed in the repository and the .jar file is in the classpath.

I want to download objects (css , jpeg, html ,png ) using sockets in java without using httpurlconnection . How can i do this with simple socket library ?
View Replies View RelatedSo I'd like to make like a library of tiles, and it isn't too big, which I could just call using a method, and I would specificy what information I need to get, and it would return that information.
For example, a small section of the tiles library is grass_tile, I call this library and specify what I need, and in this case let's say I need the width, or can the character enter it from north? or can the character just stand on it? So it's like a library or array, with sections of it being named by tiles, and by mentioning these tiles I can information about them.
gTile("grass","walkon") will return true, first because I specifiy grass, and yes the character can walk on grass, so it returns a boolean value of true.
gTile("stone","width") will return 16, first because I specify stone, and the stone's png image size is 16.
What I'm asking is not for how to work out if the character can walk on the tile, or read the width of a tile, but can I create like a library from which I can obtain information by giving the name of the tile, and then telling it what info I need.
If up key pressed && gTile((yTILE + 1).name(),"walkon") == true then moveChar("up")

View Replies View Relatedi have been given a homework assignment where I have to get rid of a stack object I wrote for a program and replace it with the Stack<E> library java offers ie:
public class Stack<E> extends Vector<E> {
public Stack(); // constructor
public Boolean empty();
public E peek();
public E pop();
public E push(E item);
}
my question is do i have to actually write all these methods? Or can i just construct a stack and use the methods?
On the first run, everything loads perfectly. The second run, I get the "Could not locate OpenAL library." error. I have the most updated version of slick/lwjgl. I have no clue why this is happening.I should also say, this error only happens if I get a message in the console saying "1 device not closed.." message for OpenAL. Here's the error message:

I want to follow this tutorial on YouTube but I cant seem to find the JRE System Library on NetBeans? So I decided to just get Eclipse but when I unzip the download and click either .exe files(I only see two .exe files) it gives me this message:
"The Eclipse executable launcher was unable to locate it's companion shared library."
Which ultimately prevents me from using the software completely.
May I know what it means when you say "What is the OOP mechanism is used to link the library and the swing framework?"
What are the examples of OOP mechanisms? Is there a website explaining this in detail?

I have the following problem:
I need to make a relation (OneToMany) between a entity on my server and a entity in my library (ManyToOne).
My program consists of 3 main components:
- a client (who uses session beans to query the server)
- a server (which contains entity's)
- a lib which is shared between the client and the server. (which also contains entity's)
Here is the thing I want to do:
Class on my Server:
@Entity
public class ClassOnServer implements Serializable{
@Id
private int uid;
@OneToMany(cascade=ALL, mappedBy="relation")
private Set<ClassOnServer> relation1; //This is no problem, because the server can import the library
}
Class on my Library:
@Entity
public class ClassInLibrary implements Serializable{
@Id
private int uid;
@ManyToOne
private ClassOnServer relation2; //This gives an error because ClassOnServer can not be imported into the library
}
It's not an option to move ClassOnServer to my lib because this would ruin the whole architecture.

I am trying to write the id3 tags using mp3agic library. The problem is it does not update the id3 tags for the mp3 files which already contains id3 tags but it only updates the file that have id3 tags which are empty.
When i look at the newly created files, they contains the older tags. Then i wrote a script to access id3 tags through mp3agic
id3v1Tag.getArtist()
then it was showing updated tags.
Why it is showing updated tags even if they are not really updated in folder where i visits ?
I'm trying to make a calendar that, when you click on the date, the result are stored in a map and visualized in a table that refers to a container.
I successfully created the map mechanism, but I have a problem on the list....
I add the rows in this way:
Object newItemId = container.addItem();
Item riga = container.getItem(newItemId);
riga.getItemProperty("Timestamp").setValue(fara);
riga.getItemProperty("Date").setValue(asa);
.
How can I delete a row in the list, when all I have in input is the "Timestamp" information, in a Long value?
