How would you efficiently store and access stats in Java?
Java Code:
Monster[Attacked].takeDamage[Attackers damage modified by Defenders defense] mh_sh_highlight_all('java');
The purpose is for something like that... Trying to work towards that.
How would you store the stats for units (hp, mp, strength, defense, etc.) ?
I'm making a program that finds the maximum, minimum, and average values in an integer input ended with a negative number. For example, 4 5 6 -1 is min:4, max:6, and average:5.
It's supposed to handle faulty input in two situations:
1.When an input other than integers is given, the user is given a second chance to give a proper input.
2.When no numbers are given (which is only possible by giving nothing but the negative number end mark), an error message is given because diving by zero integers is impossible.
All the math works fine, but for some reason a proper input in the second chance doesn't. Failing the second chance works, and giving proper input all the way through works. If I fail the first input and then give a proper integer input on the second chance, the program skips over the calculation and gives the divide by zero error. All I could understand from the debugger is that the program is recognizing whatever the first number in that input is, but still keeps the number of numbers as zero (so it's not looping to compare all the numbers in the line either).
import java.util.Scanner;
public class FindNumbers implements FindNumbersInterface
{
double average;
double sum;
int numberOfNumbers;
int total;

I am making a program to read data from excel files and store them in tables by their IDs. I have managed to read all the data from excel files as a string and store them in a table. But my project is to store them in table by ascending IDs. I have created the comparator in another class but when i call it in the main class nothing happened. The data that I have to store is like the below:
ID Name Salary
50 christine 2349000
43 paulina 1245874
54 laura 4587894
23 efi 3456457
43 jim 4512878

import java.io.FileInputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;

I have a textbox called "answer" and 10 different buttons on a form. Now what i would like to do is click the button and have the Button Text in the textbox with the already present text.
So if i click the button 1 it should automatically recognize the clicked button and have its text copied to textbox.
I know the '.get' method but lets say i have 100 buttons so i cant repeat it for every single one of them.
answer.setText(answer.getText() + ___________________);

I've got a CDI bean which is a facade for a JPA entity. Such entity has got a many to one relationship with itself and I've got the following method:
public Set<Account> getChildren() {
return this.children;
}
which is called in a JSF/Facelets page:
<h:commandLink action="#{accountController.destroy}" value="#{bundle.ListAccountDestroyLink}" rendered="#{item.children.size() == 0}"/>I then decided to return an unmodifiable set and changed getChildren() accordingly:
public Set<Account> getChildren() {
return Collections.unmodifiableSet(children);
}
The page now reports this error:
java.lang.IllegalAccessException: Class javax.el.BeanELResolver can not access a member of class java.util.Collections$UnmodifiableCollection with modifiers "public"

javax.el.BeanELResolver is incorrectly failing because it's trying to invoke the size() method using reflection without correctly taking into account the method visibility (which is indeed invokable programmatically). I'm running NetBeans 6.8, Glassfish 3.0 and jdk1.6.0_17.
Is this a bug in BeanELResolver?
I have a doubt about how to design a web application which has their persistent objects in a service layer in a remote server, i mean a business application. So, once we have a web application as a client of this remote business application, how those persistent objects should be mapped in web front?
Should I either pack all jpa annotated classes into the web front application or there is another neat way to do this?
I was intending in copy all persistent classes present in the remote business application into the web app package, i know it's not the best way to get what i need.
What is a more appropriate design for a web application which must get some objects from a remote business application and persist some other objects there?
I have a requirement where I have to send a file from a local system to unix box(present on client side) using java code.I have developed a code that is successfully sending the file from local system to client side unix box (I am connecting to client side unix box using VPN) provided I run the code in my eclipse IDE present in local system. But when I am running the same code in the unix box it is throwing null pointer exception.Might be the unix system is not recognising the local system. Please find the code.

Hello World program. We had to build it. Write a basic Java program that will implement one class to store a state of a project. The class should have one property to store a textual name of the state. When a object of this class is created the initial state should be "Open".
1) Class should have one method next() which will move the project to the next step in the sequence: Open - In progress - Closed.If next method is called for a project in the Closed state it should do nothing.
2) Class should have a method close() which will move the project into the Closed state.
3) Class should have a method print() that will output a current state of the project.

I have been working on this thing for almost a week, and really don't have a clue on what to do. I know I have to use a string = open, and I know I have to create an object. I don't have a clue on how to do this. I have read the chapter so many times, I almost memorized it, but what he wants is nothing like our demo in the book. the Book used set and get, and utility scanner, but he doesn't want any of that. Just a basic code that will move from Open --- in progress --- closed.
The best I can tell what he wants is when I set the object to open it will display " project is open", then when I set it to " in progress" it will read project is "in progress". I don't have a clue what close is suppose to do, or the print method.
