Java Eclipse Health Bar

May 31, 2014

I'm programming a game in Eclipse using Java for Android. I was wondering if any good example of a Health bar using Images. All I can find is people using the progress bar, but i feel that's unprofessional looking.

My goal is to layer 2 images. 1 being the frame of the health bar, 1 being the value of the health bar. I figured it would be something like moving the value health bar image few pixels over depending on the variable of health.

Java Game Health

Jan 20, 2015

I'm building this custom project in stages, and I'm having difficulty getting the health of the player and the enemy to change. Upon compiling, I'll select weapon 1, then choose action 1 (basic attack), and the health of both the player and the enemy will stay at 15 and 10.There are no errors when compiling.

import java.util.Scanner;
public class CustomProject
{
public static void main(String[]args) {
Scanner sc = new Scanner(System.in);
it hp = 0;
int potionsleft = 0;
int choice1 = 0;
int weapon = 0;
int enemy1hp = 10;
//int newenemy1hp = 0;

Java EE SDK :: How To Set The Class Path When Using Technology In Eclipse

Nov 1, 2011

I'm developing a JavaEE system with several applications on a Weblogic AS (10.3.5) using Eclipse indigo with OEPE plugin. I turned my computer off, turned it back on, started the eclipse, and all of a sudden I get class-path errors all over the place (didn't change a thing).

Now let me get this straight:

1. Say I have an application with one EAR project that contains an EJB project and an EJBClient project (both in the deployment assembly).
2. I have written a new regular Java project, and I want to use it in both the EJB and EJBClient projects (it needs to be visible to them).
3. As far as I know, I can simply add this Java project to the EAR project's deployment assembly, and it will be visible to the EJB and EJBClient projects.
4. This has been working for me so far, but now I get class-path errors and I have to add this Java project to the build path of each project.

How should I set the class-path when using JavaEE technology in Eclipse?

Java Eclipse - Changing Color Output Elements

Oct 29, 2014

how to change the color of an output element in Eclipse? Can't seem to find it anywhere on the internet.For example, a response to my question 'What color do you want?' could be 'red'. I added an if-statement, which states if input = red, start using a red colored 'X' as string for further output.How do I obtain the color red for my X?? Or isn't it possible changing the color of output elements?

Exporting A Java Program From Eclipse That Only Runs In Console

Oct 11, 2014

I have recently revisited a program I wrote a few years ago, that runs absolutely fine in the console in Eclipse. However, when I export it as a Runnable Jar File, then open the file on my Desktop, nothing happens.How do I get the program to export so that when I open the file, a window opens that acts as the console (so the program can run in it)?

Extracting Eclipse Project As Runnable Java Not Working

Feb 5, 2014

I've been working quite a bit with a login system the past couple of months and I now have a version that I would like to try "for real" by extracting it as a runnable .jar or .exe file. I've looked at a couple of guides that told me how to do this properly, but even after following every step precisely it didn't work.

One of the guides I tried: 3 Ways to Create an Executable File from Eclipse - wikiHow

Double clicking the file or selecting it and pressing enter does nothing, the computer loads for a second and then nothing happens. I don't receive any visible errors when extracting the program, either.

However, when running the file from the command prompt I do receive an odd error:
Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.

C:UsersUserName>java -jar Login.jar
Exception in thread "main" java.lang.IllegalArgumentException: input == null!

at LoginSystem.Data.<init>(Data.java:309)
at LoginSystem.MainFrame.<init>(MainFrame.java:42)
at LoginSystem.MainFrame.main(MainFrame.java:457)

C:UsersUserName>

I must say I don't quite understand the error, it seems to be unable to load an image which is odd considering the program works fine without any errors at all in Eclipse.

Simple Program In Java (Eclipse) That Converts Fahrenheit To Celsius

Apr 10, 2014

I've made a simple program in Java (Eclipse) that converts Fahrenheit to Celsius.The class is:

Java Code: package ehu.student;

/*--------------------------------------------------------------*/
/*Clase que dado una temperatura en Fahrenheit la canvierte en C*/
/*--------------------------------------------------------------*/
public float farenheit2celsius (float d){
float celsius, aux;

[code]...

When I write t.farenheit2celsius(25.6), appears the following error: "The method farenheit2celsisus(float) in the type ConversorTemperaturas is not applicable for the arguments (double)"If i change in the class the type float for double there is not problem. Why can't i use the type float?

Difference Between Eclipse And JDK?

Feb 27, 2014

I'm not sure if that's the right place to ask

But I am a bit confused:

I know that JDK means "Java Development Kit" , but isn't Eclipse the same thing? (so why it's called "IDE"?)

Or maybe Eclipse is a type of JDK?

Or actually JDK and Eclipse are 2 different things
