Here is the outline of what the program should do: [URL] .....
So far I've got the very basics in place, I can't really figure out ptplot despite trying to research it online. The only other thing I know is that arrays are not to be used (initially I intended on using them). Here's my code:
//The next line imports the java.io package
import java.io.*;
//Imports math language
import java.lang.Math;
//import ptolemy.plot.*;
//Sets up class
public class cp5 {
//Declares class method called 'main'.
Code] ....

that i started to learn programming and i started with java. so there is a book that i'm on it right now called "Pearson Absolute Java 5th Edition" by Walter Savitch anyway i'm on a project in fifth season which i have to create a class named HotDogStand that operates several hotdog stands distributed throughout town. the whole program is clear. although its so easy to accomplish , my question is more about debugging. so here is the code:
public class HotDogStand
{
private int id; //id number of hotdog stand
private int hotDogsPerDay; //hotdogs sold by one stand
private static int totalHotDogs; //the static value for total hotdogs sold by all the stands
public HotDogStand (int newID, int hotDogsPerDay) {
this.id = newID;
this.hotDogsPerDay = hotDogsPerDay;
totalHotDogs += hotDogsPerDay; //to add the value every time the user uses the constructor (every time the user creates an object)
[code]....
everything works fine. but my question is what if someone use a constructor again? you see if in the main method someone do this after creating the object "stand3":
HotDogStand stand3 = new HotDogStand(3, 43);
stand3 = new HotDogStand(3,40);
i know that it's logical to use setter method but this program doesn't have one. if someone do the thing i wrote above, the calculation of static variable, totalHotDogs will be all wrong. because of totalHotDogs += hotDogsPerDay; it will add another value for the same object. how can i tell the machine to ignore the second (or more) invocation of the constructor for the same object?

I made a kind of maze game that includes the class keylistener and orients a object, i can't find where the program tracks this object (where its x and y coordinates are). So now my object can move freely through all walls and i want it to bounce back or at least something to happen when the object reaches a wall.
I want to find a way to limit my objects movement and because i cant find where the coordinates or variable for this object is i cannot limit its movement

I want to develop a Java program that uses OpenScript APIs to test my applications. The OpenScript framework automatically creates the Java Code so I was thinking of either using this code or create my own using the APIs.
I tried both options using NetBeans but I'm getting errors everywhere starting with the library import. I'm pretty new to Java so I'm sure I'm missing a lot of things here. I pasted the code below from the OpenScript framework that want to use in a stand-alone file for your reference.,
import oracle.oats.scripting.modules.basic.api.*;
import oracle.oats.scripting.modules.browser.api.*;
import oracle.oats.scripting.modules.functionalTest.api.*;
import oracle.oats.scripting.modules.utilities.api.*;

I've written a java application with several classes all in the same .java file. It works just fine. Now, I've broken it up so that each class has its own .java file. Still works fine. My next step is to put those classes into a package, but I'm not about to get the program to run.The .java source files are all in /home/user/src
I've set the CLASSPATH to /home/user/src..All of the source files have "package com.myfirm.program" on the first line.I compiled the application with:
javac -d . File1.java File2.java File3.java (etc...)
the compiler created the directory: /home/user/src/com/myfirm/program and put all of the .class files in there.So how do I get the program to run? if I run from /home/usr/src
java File1
I get: Exception in thread "main" java.lang.NoClassDefFoundError: File1 (wrong name: com/myfirm/program/Program)

What happens when we add PATH in our Environment Variable How does Eclipse or Other IDE use it?
Second Question is.
For Java SE we declare a Path Variable but for Java EE we do not add any library?(I know we add some jar file like for Servlet(Servlet-api.jar) and for EJB(Ejb.jar),But What is actaul difference?

I know about coding in general, Java, C, Python, SQL etc. but I barely know anything about making code come together on the web. I have a vague idea about what things like libraries and frameworks are,I'm interested in making a web application with which relies on Java do to the data processing. The idea is that the user inputs some messages, clicks submit, the text is taken away and processed, and the results are displayed on the screen. I would like the UI to be smooth with a modern look and feel.
Also, I usually do programming on Windows but I could also use Linux, so if I'll come across any specific drawbacks using Windows.

Write a function (or functions) that given a collection of files will produce a sum of integers from each line of each file. Each file can have any number of lines from 1 to N. Each line can contain only one integer and no other alphanumeric characters. All of the numbers from all of the files should be added to the final result. The result is just one number.
For either, what we are looking for is:
1. Clear separation of concerns
2. Well defined objects / interfaces
3. Application of good OO design principles to solve the problem
4. No code duplication
5. Test Driven Development
6. Well refactored code
7. Well tested code

I'm converting from ASP to Java for a legacy site. I believe the first part of the if statement is right but I'm having an issue within the else staetment. I'm getting date is undefined, I've tried using getYear and getDate but have not been successful.
ASP:
If Request("action") = "results" Then
aMonth = Request("selMonth")
aDate = cint(Request("selDate"))
aYear = cint(Request("selYear"))
Else
aMonth = UCase(MonthName(Month(Date()),true))
aDate = Day(DateAdd("d",-1,date()))
aYear = Year(Date())

how 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.
