View Replies View RelatedI am developing a number of Data Structures in Bluej. Iv created a nice little arraylist program, and want to add a password generator to this program. People are already prestored within the arraylist, and contain attributes such as ID, name, password, etc. I can search a persons name within the list and then view their ID, password, and encrypted password. I want to add a field which will show password strength, bare in mind the password is already stored within the program and will not be entered via the user.
I understand that this could be done via a regular expression, or using some count method where certain goals/sets of characters increase the count which determine strength.
So I'm trying to make a simple program which takes in an argument (target) and then looks through an ArrayList of strings. If it finds a string that begins with (target) then it will return the index of that string. If it doesn't find a string which begins with (target) then it will return -1 instead.
For some reason, the program is always returning -1, rather than the index of the string within the ArrayList when there is one which matches the search criteria.
Here is the code:
public int getIndex(ArrayList<String> text, String target)
{
int i = 0;
int index = -1;
boolean found = false;

I am trying to design properly a simple 1to50 game (yes, the one that is so popular among mobile apps), but as a web application that allows two player games. I tried to document myself on the technologies I could use and came to the decision that some kind of Java would be suitable. I know that HTML, HTML5, CSS, JavaScript are client side languages with what I can basically design the client application that runs on a web browser. I installed Tomcat web server, configured Java Servlet API, done some research on Servlets and JSP, but I still cannot really imagine how all of this can work. Servlets form the Controller, JSP files the Model? How can I make them communicate, how can Servlets "tell" JSP files what to dynamically generate? Can JSP files communicate with JavaScript? Is JavaScript even necessary?
I thought that this question is not basically about a specific thing regarding JSP or Servlets, more about design and general concept, that is why I put this question under beginning Java.

To get starated I now want to create a simple JFrame application that works in the following way. On the opening screen I want to present 4 buttons. Based on the selection I want the JFrame to change layout and components so that the same JFrame behind the scenes contains 5 layouts but only one visible at any time. What is the best way to accomplish this? Or should I do this in another way using multiple JFrames or similar?

how to structure simple programs (i.e. one-method algorithms for a simple purpose). There are a few different ways that I have been doing it, but I want to be consistent. Should I put both the one-method algorithm (e.g. a factorial function) and the main method that executes the algorithm into the same class and then export it to an executable .jar file for use? Or should I create one class for the algorithm and another for the main method that executes the algorithm? In addition, is there any reason that I should out these classes in a package before I export it?
As another similar question, if I have constructed two distinct classes with two separate purposes, and they are both used in the construction of a single program, then would it be best to just put the main method in a third, separate class or should I put it in one of the two classes?

I need to do a simple while loop pay calculator. I am very new and not sure what I need to do to put all the requirements in the new code from another code. Here is my code that doesn't work yet.
1.Place the wage calculation routines in a while loop.
2.Allow the user to input an individual's hours worked.
3.Accumulate the total regular hours worked, the overtime hours worked, the amount of the regular pay, the amount of overtime pay, and the total payroll, for all of the employees entered.
4.Allow the user to enter a zero (0) as the Boolean expression to end the loop.
5.When the loop ends print out all of the accumulated totals with appropriate labels, each on a separate line.
import java.util.Scanner;
public class WhileLoopPayCalc
{
public static void main(String [] args) {
final double REGULAR_HOURS = 40f;
final double HOURLY_WAGE = 12.5f;
final double OVERTIME = 1.5f;

I am totally new to java. How to convert the below java code to an executable file?
var intInterval = 0
function importdata(){
filename = "C:1.txt";
AmiBroker1 = new ActiveXObject("Broker.Application" );
AmiBroker1.Import( 0, filename, "custom.format" );
AmiBroker1.RefreshAll();
}
It simply imports numerical data from 1.txt into an application amibroker. Also this import function has to be in a loop of 60 seconds.
I want to do a simple search and replace regular expression of lines. I am very unfamilar with Java regular expressions, and I'm not sure how to do something as simple as what I want to do. I have lines that look like this...
Java Code : access_log /home/%USER%/access_log mh_sh_highlight_all('java');
I want them changed so %USER% changes to a string, such as "cyrus," so they appear like this ...
Java Code: access_log /home/cyrus/access_log mh_sh_highlight_all('java');
The reason I want to use regular expressions is because I want to use the replaceAll method of the java.lang.String object. If I use replace I have to convert my strings into char arrays, and my code becomes bulky.
