Use Of Imports
Mar 25, 2014
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?

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?

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?
