How To Manage Imports
Feb 27, 2015My 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?
How To Manage Old Requests Due To Context Path Change
Jun 12, 2014I 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?
How To Add Libraries To JCreator
Nov 18, 2014I've been trying this for hours but it's not working. I'm trying to add the sea glass look and feel library to my project but I still get the error:
Exception in thread "main" java.lang.NoClassDefFoundError: List (wrong name: list)
What should I do? I've added the library to "project settings >Required Libraries" and did not forget to check the box. I've also imported the L&F so it can't be that.
JList Manipulation - How Operating Systems Manage Processes
Sep 29, 2014I 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 {

Java-8 :: How To Manage Untrusted / Unsigned Internal Apps
Apr 10, 2015I'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)?

View Replies View RelatedUsing JFrame In Java?
Apr 16, 2014how to use JFrames and button and so on in Java. I found this video on youtube and followed it along, however even though my program is virtually identical to his, I'm still getting errors.
Here's the video I was watching: Video
And here's my code:
import javax.swing.*; //Imports JFrame and JButton for use
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.*;
import java.awt.*;
import java.awt.event.*;
public class swing
[code]....
The reason why I'm importing some many things is I'm trying everything to try fix my problem.
He's the error messages I'm getting:
frame2.add(panel);
^
C:UsersWindows 8Documentsswing.java:42: error: illegal start of expression
frame2.add(panel);
[code]....
I used to make the button just create another frame without additional labels but I changed it to be even more similar to his program just to rule everything out. Also initially my program varied quite a bit, I've changed everything to be like his. Even without the ";" error I got, I kept telling me I was not allowed have my class as static, even though the guy in the video has it set to static. Also I don't think my "setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);" is working as it doesn't change color.
I think the problem is with my panel, it isn't adding to the frame for some reason.I'm using TextPad7 and I'm using Win8.
C:UsersWindows 8Documentsswing.java:42: error: '(' or '[' expected
frame2.add(panel);
^
C:UsersWindows 8Documentsswing.java:42: error: illegal start of expression
frame2.add(panel);
[code]....
I would also like to point out that some of the comments are out of date and are referencing the way the program was before I made it just like his. For example I know my second class isn't inheriting the first class.
