Basic Time Translation Loop
Oct 25, 2014
I am new to programming so for loops are a little confusing to me still but basically what I am doing is making a small java rpg game and I want to add in a time element to it so your character gets things like promotions and such after a certain amount of time playing.
for (int x = months; x < 12; years++) {
for (int y = weeks; y < 4; months++) {
for (int z = days; z < 7; weeks++) {
for (int j = hours; j < 24; days++) {
for (int k = minutes; k < 60; hours++) {
}
}
}
}
}
That's what I have so far but I am getting a logical error/ infinite loop when I run. I have added each unit of time as a static variable so there's no problem there.

I am a visual effects artist not a programmer but I wanna create a very basic translation software to improve english language in primary school students in my country. I cannot program at all except html and css but I am willing to do and learn whatever it takes to make this work. I don't know where to start from or what language to use. The structure of the program is to type an english word and then it must give out a translation of my local language and vice versa and I would like to add audio to the words.

I am trying to create a basic graphical user interface for sequence translation (including a JTextField for the description of a sequence and status of function button pressed e.g. “simple” translation and input and output TextFields). This involves a number of different class files. I cannot get my user interface to do what I want and I think I have problems with my "actionPerformed" method. How the code should be linked together?
public void actionPerformed(ActionEvent event) {
try {
// Get the description, content and result
String d = tool.getDescription();
String input = tool.getInputText();
Stringr = translation.getResult();
[code]....

I seem to have done it right, but it doesn't work... What is wrong?

So I need to make a for loop for this problem: A certain type of bacteria doubles its population every twelve hours. If you start with a population of 1000, how many hours will it take for the population to exceed 1,000,000? Output needs to be in table format, such as:
Hours: - Population:
0 ------- 1000
12 ----- 2000
24 ----- 4000
I've created the code, but don't understand how to increment hours by 12 and double the population by 2 each time.
public class Population
{
public static void main (String[] args) {
int hours = 0;
int population;

I have the below piece of code in my jsp page.
<% double randomNum= Math.random(); %>
<%= randomNum%>
Now I am trying to run this jsp, it will be translated into servlet. When i checked the generated servlet I found both the above code snippet(scriplet and expression) came in to _jspService method. But in the internet and in many other book i found that scriplet and expression portions will come in the doGet/doPost method (which will be called from jspservice).
So any specific reason why in this case it went in to jspservice method (though I am getting desired output)? I am using tomcat 6.

The project is to develop the game Translate the Word .... It is asking user to translate a word proposed to and check if the input response is correct. At the end of the game score will be calculated and displayed.
Game Play :
1 - Ask the user to specify , through the console , its name and the number of words to offer . It is up to you to handle exceptions (eg number of words greater than the number you provided )
2 - Recover user response ( the word translated ) and check whether to continue . (eg you want to continue (y / n)) after each proposal.
3 - compare the response of the user with that which is preset for the word in question .
4 - Show the score at the end ( or at the breakpoint ) .
5 - Save the file in a user name , the score , the number of questions and the start date and end of the game played .
Some notes to consider :
1 - The language (eg, English - French , English - Arabic , etc. . ): It is up to you to specify the language adopted in the game and inform the user of your choice.
2 - The word bank to offer : It is up to you to develop the appropriate means to get the words to propose to the user. That said , the words and their translations can be retrieved :
a. a TXT file
b . an XML file . ( Tutorials DOM and SAX )
c . CSV file ( OpenCSV Tutorial )
d. a database ( Tutorial Access)
e . through APIs (eg Wordnet and google translate etc . ) .
f . a combination of the previous options a, bc , d and / or e . (eg words stored in a txt file and answers retrieved from the api google translate)
g . etc. .
Examples of files and databases are attached to the project statement . You will need to add one or more external libraries to your project. Click here for details on adding external libraries to Netbeans .
3 - A user will be associated with the question score if he can translate the word correctly. The score for each question can be calculated based on the number of words / questions to be proposed .
Development : In this project you will need at least a class called Question to encapsulate the word and its translations and provide all necessary methods to manipulate the object type Question.
An interface called IParser to make extensible project. Any class that implements IParser is a parser file (XML , TXT , CSV , etc.). / Database. In your project there will be a single class that implements IParser and will be used to retrieve words and their translations.
Add the ability to store the questions and answers of the user on the hard disk. Make the class Serializable Question

I am working on an assignment that I can't seem to figure out the final part to. The program takes in course data such as the time the class starts and how long it lasts. The time is in military time (0000 - 2400)
I need the output time to be the time the class started, plus the length of the class, and displayed in military time.
for example,
Start Time = 0930
Length = 50 minutes
Endtime = 1020
I can't for the life of me figure out how to do this. I have gotten a program that works for this time and minutes, and displays the correct 1020. But when I change the information to say
Start time: 0700
Length = 90 minutes
I get:
Endtime = 90
90 is technically correct, the way the formula is setup, but I need it to display 0900 not 90.
Here is the code that I have. Be easy, I'm still learning, and this is just the file I created to get the formula to work. Also, the verbose in here is just for my own debugging to make sure values should be what I'm expecting them to be.
public class calc
{
public static void main(String[] args) {
double hours, minutes, length;
double temp;
int time = 2400;
hours = time / 100;
System.out.println("Hours are: " + hours);

I have two classes. time_runner is used for testing my code.
This is what I'm using to test my code:
class time_runner
{
public static void main(String str[]) throws IOException {
Time time1 = new Time(14, 56);
System.out.println("time1: " + time1);
System.out.println("convert time1 to standard time: " + time1.convert());
System.out.println("time1: " + time1);
System.out.print("increment time1 five times: ");
time1.increment();
[code]....
The two constructors are "Time()", which is the default constructor that sets the time to 1200, and "Time(int h, int m)" Which says If h is between 1 and 23 inclusive, set the hour to h. Otherwise, set the hour to 0. If m is between 0 and 59 inclusive, set the minutes to m. Otherwise, set the minutes to 0. Those are my two constructors that I pretty much have down. The three methods however I'm having trouble with. The "String toString()" Returns the time as a String of length 4. The "String convert()" Returns the time as a String converted from military time to standard time. The "void increment()" Advances the time by one minute.
public class Time {
private int hour;
private int minute;
public Time(int h, int m) {
if(h > 1 && h < 23)
hour = h;

im considered quite the "javanoob" as my account name states..The assignment is to basically take a number that is entered by a user, and based off what they type in, display a corresponding grade letter. For example, if they enter a number between 90-100, they should receive a response that they received an "A". Now, this is fairly simple using an if/else statement, but my professor wanted us to implement this, using a switch case to teach us the difference.
import java.util.*;
public class SwitchTest
{
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
System.out.println("Please enter a number to find out what letter grade you have recieved");

I moved some static html pages I was hosting from apache into tomcat. (no point in running two servers) This works as expected, but I'm having trouble with the authentication part. In apache the authentication was handled by htaccess. I tried various tutorials on the web about configuring basic authentication in tomcat using WEB-INF/web.xml in tomcat, but I'm not sure this approach applies to static html pages. Using basic authentication for static html in tomcat?

how I would go about having a moving sprite on a page, such as a virtual pet kind of thing. I've tried searching for it through the years and I've tried it with what I know on my own, but things just act up every time. Either:
A.) The sprite moves (respondent to key strokes, of course), but leaves a trail of its image behind itself.
B.) The background image writes, but for some reason the second image does not write, or is lost behind the background.
I'm sure these are simple issues for most of you, but I've tried going about this for a while now with no luck. What I'm trying to do I'm trying to write a virtual pet game, and I would eventually love to make it move around randomly like an A.I. that's pathfinding, but I've got ideas about that, just I need to know how to make it move period first, everything else I think I could figure out on my own.

I am setting up a standalone JNDI and loading a Datasource to the JNDI. DataSource I use is:
org.apache.commons.dbcp.BasicDataSource
The JNDI is set up as follows
String detectorHost = InetAddress.getLocalHost().getHostName();
System.out.println("detectorHost: " + detectorHost);
System.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
final NamingBeanImpl namingInfo = new NamingBeanImpl(); namingInfo.start();
[Code] ....
I get the following exception
javax.naming.CommunicationException [Root exception is java.io.NotSerializableException: org.apache.commons.dbcp.BasicDataSource] at org.jnp.interfaces.NamingContext.bind(NamingContext.java:677) at org.jnp.interfaces.NamingContext.bind(NamingContext.java:611) at javax.naming.InitialContext.bind(Unknown Source) at com.lombardrisk.reform.integration.ReformIntegration.createJNDIServer(ReformIntegration.java:93)
[Code] ....
I don't quite follow why I am getting a NotSerializableException exception, this is a local JNDI in the same JVM and not a remote JNDI. Not sure why this occurs.

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

I am currently working on a application for a car park system. It uses GUI created by myself and holds 15 parking spaces. The user has the option to add, delete or search for a specific car. When the user adds a new car, details of the car are entered, the cars registration number (saved as a string), and the user had to check one raido button if the car is expensive, large or normal.
Once this information is entered a new instance of a vehicle will be created and the bay the car is allocated to turns green and stored in one of three arrays(expensive, normal or large). I also have a fourth array for creating the parking spaces.Each array can only hold 5 vehicles apart from the fourth which can hold all 15. When searching for a vehicle the user enters the registration of the vehicle they want to find, but I have to search through all three arrays to find it, and if it does not exist showing a message saying so.These are my three arrays
public static ParkingBay[] regularBays = new ParkingBay[5];
public static ParkingBay[] largeBays = new ParkingBay[5];
public static ParkingBay[] expensiveBays = new ParkingBay[5];
String Registration; - saves registration entered from add form
String RegistrationNumber; - saves registration number from search form
I need to search to see if RegistrationNumber is in either of the three arrays if not show a message saying otherwise

I think its a standard concept but just not getting it. I have 3 classes:
1) Base class
2) Derived class, which extends base
3) TestClass
public class Base {
public void display() {
System.out.println("Display method in Base");
}
}
class Derived extends Base {
public void display() {
System.out.println("display method in Derived");
[Code] .....
So if i run this, my results are:
Display method in Base
display method in Derived
display method in Derived
Thats cool, no problems there, but if i change my Display method in Base and Derived to static methods then the results become:
Display method in Base
display method in Derived
Display method in Base
So why oh why does obj3.display() now print "Display method in Base"?
(and yes I know the calls should be static calls, but for sake of arguments -- or is that the whole problem, that technically obj3.display() is an incorrect call as it can only be Base.display() or Derived.display() when display() is a static method ).

You have to create a very basic hangman type of game. Open Notepad and create a list of at least ten words in a text file. Save the file as a .txt file and use it to read words for the game. In this game you do not have to show pictures but you do need to keep track of the amount of times that the user has guessed wrong. When the game starts, show the amount of characters in the word represented as dashes and ask the user to type in a letter. if the user guesses correctly show the word again with the correct letter filled in the correct positions(s) and if the user correctly guessed the word, show a message. If the user guesses wrong, keep track of the body parts that needs to be reduced with every wrong guess and inform the user as well, also show a message.
I'm struggling with reading the file, showing the amount of parts left and asking the user to play again. Here is the code:
package hangman;
/**
*
* @author
*/
import java.nio.*;
import java.io.*;
import java.util.*;
public class HangMan {
