ERROR: ResultsModel cannot be resolved to a type
I have an assignment in which I have to:
1. Create a bank file with at least 10 records that include an id#, balance, and last name
2. Create another file that will read these records and then create an array of Bank Account objects
3. Create checkboxes that allow the user to select how they want the data sorted
4. List the total number of accounts at the bottom of the GUI
I've created the file no problem that actually writes the ten records. I was able to have the files be read sequentially with System.out.println(), but I can't figure out how to convert these into an array of Bank Account objects and have them show up in a scroll pane. I tried using string builder and array builder, but I couldn't figure out how to turn them into components. I then tried making an Account class to have them be sorted with comparators, but I had the same problem of actually getting them into the scroll pane. Also, as soon as I added in those methods for the GUI, the while loop wouldn't display the array information in system.out.println. Here is my code for the GUI that doesn't display anything with println ...

I'm working on this weeks assignment and I've gotten stuck on passing information from one class to another. We are working with abstract classes this week, and the BankAccount class is the Abstract class that is extended by the CheckingAccount and the SavingsAccount classes. The Bank class is where the user inputs his/her information to process the commands. How can I work this to where the instructions are passed from the main in the Bank class to the different Account classes to actually perform the instructions?
BankAccount:
/*

*/
package bankaccount;
abstract class BankAccount {
private final BankAccount acctID;
private int acctBalance = 0;
public BankAccount checking;
public BankAccount savings;
[Code] ....
I can attach a PDF of the instructions if that will provide additional insight to this. I'm sure I'll ask additional questions as we go, but I'm trying to get this to work right and figure out what I'm doing wrong.
public class BankAccount
{
String name;
int accountID;
double balance;
}
public void setAcct ( String nam, double acctID)
[Code] ....
1. Create a class called BankAccount
a. It will be a generic simple type of BankAccount
2. BankAccount will contain variables to store:
a. the owner/owners of the account
b. an account id
c. it may contain other basic information (up to you)
3. BankAccount will contain methods that will allow you to:
a. Set the account owners information
b. Deposit money
c. Withdraw money
d. Set balances
e. Print out transactions (think more like an atm each time an action is taken it gets printed)
4. BankAccount will contain its own main()
a. At least 2 BankAccount objects will be created and ALL of their methods called .
What to do for the print out transactions
When I try to print out the account Id for each account object, the id is always 1. But it should be 1,2,3,4,5....all the way to the number of the account generated.My question is am I missing something in the constructor or in the main method?? I am new to programming.The main method create an array of account objects and generate random balances into each account object.
import java.util.Scanner;
public class Bank {
public static void main(String[] args) {
Scanner userInput=new Scanner(System.in);
System.out.print("Enter the number of accounts to generate: ");
int numOfAccount=userInput.nextInt();
[code]....
What I have done wrong
public class BankAccount
{
String name;
int accountID;
double balance;
public void setAccount( String username, int ID, Boolean isJoint)
[Code] ....
Develop the class “Account” to be used by a bank. The Account class should have a single instance variable “balance”. Remember that balance must be a floating point number. The required methods for the Account class are shown below.
The Account class “debit” method should return a Boolean and should not allow an overdraft. If a withdraw greater than the current balance is attempted, the function should immediately return “false” and do nothing else.
Develop a test class to thoroughly test all aspects of the Account class. DO NOT change the class name or instance variable name given or the required method names as detailed below.
Account
1 constructor with no parameters (default balance to 0)
1 constructor with a balance parameter
setBalance method
getBalance method
credit method
debit method
I have the test class done, I won't need to put that in till later. My main problem is I'm not sure how I'm going to be able to get debit and setBalance to work together with each other.
public class Account
{
protected double balance;
// Constructor to initialize balance
public Account( double amount ) {
balance = amount;
[Code] ....
You can see I'm stressed out by not reading over my code. I already have the "Debit" in use, just have to change it. Which I did.
So the assignment is as follows. Develop a new class called BankAccount. A bank account has the owner's name and balance. Be sure to include a constructor that allows the client to supply the owner's name and initial balance. A bank account needs - accessors for the name and balance, mutators for making deposits and withdrawals. I have the following code :
import java.util.Scanner;
public class BankAccount{
public static void main(String [] args){
Scanner reader = new Scanner(System.in);
double name;
double balance;
double deposit;
double withdrawl;
[Code] ....
I am having trouble with my if statements. I don't know how to link the number 1 & 2 keys to deposit and withdrawal actions. Plus I am supposed to have a while loop yet don't know how to implement this so that the while loop will ask the user if they would like to make another transaction after either depositing or withdrawing.
How to fix the error with the line:
Account account1 = new account(1122, 20000.00);
import java.util.Date;
public class AccountClass {
class Account {
private int id;
private double balance;
private double annualInterestRate;
[Code] ....
I forgot to mention, the error says "account cannot be resolved to a type"
I am creating a user friendly program that allows the user to adjust the dimensions of an oval (painted onto a window) via a 'slider' Everything is fine for the most part, except in the main code- when I tried coding for a window object for some reason java didn't recognize the type (that is, I used the keyword TheWindow and java didn't recognize it) the following is the full code set across 2 classes, but I think the problem is centered around the main class.

View Replies View RelatedI was thinking to make a game where two cars are going to race against each other. I already have two gif pictures which are the cars. I do now have a background and a racer track. So we can start from here.
I have made a object with construction which I called Racers. Inside that, i wrote a PaintWindow (Where the window and much more is inside), -car1, -car2. All these is private. So I made something like this now:
package p2;
public class Race {
private Object window;
private Car car1;
private Car car2;
public Race(PaintWindow window, Car c1, Car c2) {
[Code] .....
But the problem is now that im kinda lost and I dont really know what to write anymore. How can I get a for example a green background on the whole PaintWindow with two Racers tracks and inside the racers tracks (Each car have each track) does it have to be cars. So I need to somehow import the cars inside it too. But thats the problem I need. that I dont really know what more to do. To make it easier, I have a Main-method in another class.
public static void main(String[] args) {
PaintWindow window = new PaintWindow();
Car c1 = new Car(new ImageIcon("C:/Users/Sarah/Desktop/CarBlue.GIF"));
Car c2 = new Car(new ImageIcon("C:Users/Sarah/Desktop/CarRed.GIF"));
Race race = new Race(window,c1,c2);
race.action();
if(args.length>0) {
Paintwindow.pause(2000);
window.dispose();
I'd like to learn more in Java security, namly Kerberos and SSO. The question is weather I have too weak laptop. I have 8 GB ram. How many virtualbox instances od I have to run in order to JAAS, SSO kerberos demo to simulate. For instance VM with Windows 2008 Server -> 3 GB RAM, Centos VM -> 1GB. Is 8 GB RAM in my laptop not too little?
BTW
I do not have yet experience in SSO/Kreberos but I want to know what to do in order to simulate and exercise.
I have a class "ExecuteJob" which has Print Q in the form of Priority Q.
You can keep adding job to the Q by calling one of the method in the class. However, and object cant do things simultaneity can it? While im adding a new job to the print queue, can it be executing and existing job in the print Q.
To achieve that, I would need to implement process and threads? I believe am I right? So that adding a job is independent to being removed?

Precondition: an n amount of randomly generated cards are created.
Postcondition: After a number is called, cards that has that number will have its value be true.
For example:
Precondition
Java Code:
Card 1 //Name of card
1 24 32 48 63
2 22 41 51 64
3 16 37 52 61
4 19 33 57 72
5 20 34 54 71 //Card with numbers
false false false false false
false false false false false
false false false false false
false false false false false
false false false false false //Card with boolean values to indicate marked values

So what I want to do is have a method that allows me to use the callRandomNumber method so that the matrix location with that random value is marked true for all of the boards.
I am writing a simple program to simulate a traffic light. What I want is to make them glow after each 1 second, one by one. For example: Firstly Red, then after 10 seconds, red will be put to off and yellow will start glowing and then accordingly green. This process shall continue incessantly (Just for experimental purpose). I have some arrangement done but could not figure out how to put them together in run() method of Runnable interface. I know how interthread communication works. But could not find any logic in this case when three threads will run together.

I'm very new to Java (I literally started learning it yesterday) and I've been working on a simple program that's meant to simulate interactions between optics objects and light rays.
Everything has been going really well, except that my mirrors only reflect the first ray that comes in contact with them.
Here's a screenshot : 2014-09-13 at 7.39.23 PM.jpg
I wrote 7 classes:
Main class to create the optics objectOptics class. the most important class that uses a recursive function to detect the nearest intersection point of a ray with the nearest optics object. It then calculates a reflected ray and inputs it back into the function until no intersections are found or the max recursion depth is met.Ray. creates a rays (in parametric form O + tD where O is the origin, D is the direction and t is a non-negative scalar)Object. empty abstract class used for polymorphism (so when i add more optics objects like prisms and lenses they'll share the object type)Mirror. Basically a line segment created with the Line classLine. Creates a line segmentDraw. JComponent with paintComponent function that loops through an array of shapes and draws them to the screen.
What I know so far is that the problem boils down to the checkRay() function in the Optics class. When a mirror has already reflected a ray, the line:
Intersection sec = new Intersection(ray,(Mirror)obj);
creates an intersection with a null point.
I debugged it line by line and found the problem was that my variable 't' (that is the parameter for the parametric line which represents the mirror) in the Intersection class got big values when it's meant to be between 0 and 1 (since it's a line segment), which resulted in the function returning null (as it should when 't' is not between 0 and 1).
I've confirmed with tests that this has nothing to do with the specific mirror or angle of incidence. It only occurs when a mirror has already been intersected with by a ray.
I've found out that my function:
public PVector getNormal(PVector D){
D.normalize();
return new PVector(D.y,-D.x);
}
Changes the value of the 'D' PVector of the mirror inside my 'objects' ArrayList. How can it access the private PVector 'D' from outside the Mirror class? This normalization to the direction vector is what causes the Intersection class to return null the second time around!
The problem was that in the getNormal function, the input vector argument was a reference to the 'D' vector for the mirror in my 'objects' ArrayList so the .normalize() function acted upon the original vector, changing it's value and screwing things up. The two classes I talked about:
Optics: (note line 64. this line returns a null intersection when it shouldn't)
package ofer.davidson;
import java.util.ArrayList;
public class Optics {
//Arrays to store all the optics objects and rays that are created
ArrayList<Object> objects;
ArrayList<Ray> rays;

Also why doesn't my background turn white??
