Let me explain what I'm supposed to do first.

My assignment is to take text from a dictionary entry and display it in my client area. This dictionary entry contains characters like \ " ' and...

Well, the code does compile. It's just that when I maximize or minimize the window or drag the sides of the window and let go, the rectangle, which is centered, doesn't get redrawn. I don't know if...

Ok, ty. Now, how do I make the syntax work? It's not doing what it's supposed to.

Hi,

In on of the lecture notes that was given to me by my prof, I was told that setting the ResizeRedraw value to true would allow whatever I drew on the form to be, well, resized. However, it...

Ok, I looked in the API and was able to create the scroll bars. Problem is, I can't make them scroll, even though the parameters I passed in explicitly said to have the bars around. What I'm trying...

I have a bunch of text and combo boxes. For example,

Day: [Day Combo Box]
Date: [Date Combo Box]
AMPM: [AMPM Combo Box]

I used BoxLayout.Y_AXIS to align them vertically but the boxes seem to...

Ok I got it.

A question related to layout managers though: I know BoxLayout tends to "stretch" the components to make them fit inside a panel. How do I modify the panel's dimensions?

When I add buttons to a panel, the buttons seem to take a huge amount of space. How do I get rid of the space? For example:


import java.awt.*;
import java.awt.event.*;
import javax.swing.*;...

All right I managed to get it. Thanks a bunch.

I'm still a little unclear about some of the fields in Calendar/GregorianCalendar though. I had to find out the hard day that decrementing...

Thanks, it worked perfectly.

I have another question though: Given some date, how do I find out what the date for the first day of the week is? For instance,


GregorianCalendar cal = new...

Suppose I have a week that begins with Sunday and ends with Saturday (so UMTWThFS). How do I get the date for each day of the week if, lets say, we use this month and year? I looked in the API but...

hmmm I tried that as well and I still don't get anything in the frame.

I can view each component separately if I only have one added to the frame, but not both. Does it have something to do...

I tried both. Nothing gets drawn to the panel.

frame.setLayout(new FlowLayout());

Can JComponents be nested?

I'm having a little trouble trying to nest two component classes (both extend JComponent) together. When I create the frame in my tester file, instantiate each class, and try to add both of them to...

1) How do I tell if I have java 5 or java 6 installed?

2) I have my program commented using javadoc syntax. However, when I run javadoc from the command prompt and then open the html files, I do...

The problem is that I have an ArrayList which stores objects that contain a Shape (actually a Composite shape like a Car) and (x,y) coordinates. Suppose I'm supposed to retrieve each object and the...

Hi,

I changed my add method so that it returns a JButton and it works fine. One thing I forgot to mention though was that the Box class was supposed to be a container of Buttons (each button has...

I'm trying to put all the buttons (and their icons) into a single class. However, when I try to draw just one button in a frame, it doesn't show up. I can get it to be displayed if I instantiate...

I'm stuck trying to figure out how to update the text field after I click on the button in the GUI. The number of roaches is supposed to be updated each time I click, but I can't seem to find the...

c:\fall2007\test\Homework\Due Dec 5> javac WorkerTester.java

The WorkerTester.java file as well as all the other files associated with it is located in the directory, so I don't think I have to...

ohhh, ok ty. I wasn't aware of the instanceOf.

Still getting the same problem.

eh, I just went through my class notes again and figure it out.

This is a relatively simple program but for some reason, I can't compile it. I'm pretty sure the code is correct and working.

My compiler keeps saying that it cannot find a constructor matching a...

See this is what I'm confused about: how do I know what I'm going to compare given that the compareTo() method is supposed to be able take any type of object argument? Different data types added to...

So we're supposed to modify this class, which implements Comparable, so that it accepts any type of object. The Comparable interface contains the method signature for compareTo, which I need to...

I did something along the lines of what mickinator posted up. Thx for the replies.

thx for the reply.

The goal of this problem was for us to practice handling exceptions. I actually managed to solve the problem, though my solution was rather messy. I ended up using 2 scanner...

So here's the problem



Here's what I'm trying to do.

while (flagA)
{
try {
while (flagB)

Heya, thanks for the reply but I already finished it =P.

Ok, so my goal is to draw a rectangular spiral in java. So far, I've created the Spiral Viewer class and the SpiralComponent but I'm not quite sure how I would implement the SpiralGenerator class. ...

I'm supposed to design a method that takes in a double value and translates the value into the closest letter grade. 4,3,2,1,0 denote A, B,C,D,F, respectively. + increases a grade's numerical value...

I'm trying to get this ISBN checker to work. I've used the formula from this site (http://mathworld.wolfram.com/ISBN.html) and also this site...

nvm i figured it out -.-

I was a little confused by the brief explanation that my Assembly teacher gave on pipelining. I don't think I really understand the process that well...

1) In a 4-stage non-pipelined processor,...

Thank you, that cleared some confusion up for me. That helped me finish this Bar Chart program.

However, there's one thing I don't understand from here and that is the Graphics2D.

In the...

One of the things that's been confusing me so far is why we have to override the paintcomponent() function after extending it. For example, this program draws an ellipse:

import java.awt.Color;...

Hi, I need help with drawing an ellipse that is bounded by the window it is drawn in. I have to use the Ellipse2D API.

Maybe I'm overlooking something but I can't seem to get the circle to fit...

ok cuz I thought that I could just directly access protected member data in the base class through an instance of the derived class (the uncommented part doesn't work). I'm not sure why that is...

If I do a public inheritance and the member data in the base class I'm deriving from is protected, is the only way to access the data in the base class via member/friend functions of the derived...
