How To Manage Imports
Feb 27, 2015
My first Java project contains 30+ imports, all of which are for specific classes -- I'm using NetBeans and whenever I instantiate a new, unimported class I just click on the "light bulb" and tell it to import. I'm only now starting to worry about code management and conventions.
As you can imagine, many of these imported classes live in just a few packages, like awt and file.nio. It's starting to make my code a little cluttered. In the real world, what is the convention for import statements? My instincts tell me I should just import using the .* wildcard, but how do professionals do it? If an experienced programmer were to pull my code from Github, what would they want or expect to see in the import lines of code: a bunch of specific imports, or wildcard imports?

I am a bit confused on the use of imports. I am reading a book on java and in one of their examples it starts a program with;
import java.io.*;
import java.net.*;
import java.util.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
The question I have is on the awt import.If I have import java.awt.*;I assume that that will include all I need under the awt directory but the next line, import java.awt.event.* why the java.awt.*; does not include the .event.*; directory as well?

The followings are what I see just now.....
//******************************************
Ambiguities
Wildcard imports have one problem though: they can lead to ambiguities when classes with the same name exist in two packages you import via wildcard.
Imagine the following two imports:
import foo.*;
import bar.*;
Now you want to use the class foo.Node but there is also a class bar.Node. Now you need to use non-wildcard imports to resolve the ambiguity that would happen otherwise.

I made a game but i didn't add imports, i have been told i need to have imports and it needs to be in a normal swing format or it will not pass . How to change my code to swing format?
My code is
public class TextTwist extends javax.swing.JFrame
implements java.awt.event.ActionListener
{
// hard code, should be picked from a Problem class
private String[] letters = {"F","O","C","I","E","F"};
// hard code, should be picked from a Problem class
private String[] solutions = {"ICE","OFF","FOE","FOCI","OFFICE"};
[Code] ....
How do i get the program to move on to the next one String?

I had to change context path name of my web application due to some organizational shuffle. I have successfully changed it and it has been working fine.
But what is happening is we have used old context path name in reminder and notification emails. so When users hit links from old emails, they are getting 404 Error.
Is there any way to redirect the old request which has old context path to new one?

I am attempting to use JLists to complete a program that models how operating systems manage processes. A quick synopsis of what it is supposed to do. Each process is to have a priority level (I chose to do 1 -3 with 3 being the most important) and there are supposed to be three lists. One for ready processes, blocked processes, and a running process.
My issues:
1) when I block a process it does indeed switch lists but when it is copied into the blocked list it pulls the element number instead of what the actual process number is. For ex: Say the ready list has 5 processes / I delete 2 / Leaving process 1, 2, 5. When I block 5, it gets registered in the blocked list as process 2.
2) I can't figure out how to give a label to each of my scroll panels (JLists) to signify which box is ready / blocked / and running
3) My switch button - I have commented in what I need to do but don't know how I am going to do it.
Below are my files:
Main
import java.util.Comparator;
import java.util.PriorityQueue;
import java.util.Queue;
import javax.swing.JFrame;
import javax.swing.JTextArea;
public class PQueue {
public static void main(String[] args) throws InterruptedException {
[Code] ....

I'm deploying Java 8 update 40 to my users and want to know if there's a way to manage sites that prompt the user with warnings about untrusted and unsigned applets?
i'm using the exception.sites file to manage applicable prompts/warnings for our internal sites, but doesn't look like the exception list works for untrusted and unsigned.
is there a way to manage these from an all users level, particularly with a deployment (ie, SCCM)?

Part of my app is to provide an interface to an operator to manage multiple printers of smart cards.
A JSP page displays all printers and each printer has a print button.
I want the operator to press several buttons and each button pressed starts a thread.
Threads should run in parallel and pressing a button does not cancel the processing of the previous button.
