Why should the hidden forum be only for Java?

I am currently taking a basic Java class in school. We havea project this week where we have to create a "simple choice" program where uses can follow a story by answering yes or no to given questions. I got it working as required (we are limited to use only the basic if/else statements in our Chapter 2 readings). The only thing that I think I may have wrong is that in the requirements, the instructor states that any answer that isn't yes is to be assumed no. My problem is that this is not true in my project as I have both and -if yes- and -if no- statement defined. If I don't specify the -if no-, statement then the story will read fine, but instead of ending at the specified points, it continues to read and execute all the other "else" statements that aren't specified to occur only if the answer is "no".
Below is my code. I know it's hard to understand what I just wrote. I am new to this and can't explain this well. Any advice would be appreciated. I am thinking...is there a easy way to say something to the affect:
else
if (gotoplaza.equals("no" OR "anything else"))
{out.writeln("my text here");
Again...thanks for any advice!

In the specified if statement do this:
if("yes"){
//execute code
}else{
//execute no code
}
this way if its a yes then the first statement will execute and if its anything other than yes it will run the no code.
hope this helps

Yeah it would be nice to have some place to go for my java questions. I havent found to many good java message boards. Now if they just wouldnt hide us like the step brother they never wanted

I while ago I created an Java application that seemed to work fine at commandline. However, when I turned it into an applet I get a ClassNotFoundException for java.util.HashMap. Does anyone know what that is about?
Anyway, if you want to look at the code (it is eventually supposed to be a framework for building zork-like games) you can find it here. Commandline: zork.class, applet as in the webpage submitted.
Thanks

I guess it's a Java 2 class, and the builtin JVM in MSIE understands only Java 1. Have you installed Sun's Java plugin or tried appletviewer.exe.
|

You are right, HashMap is Java2. I was so sure it was Java1...
Thanks for the help

Hello,
I am having a problem with the precision of some of my calculations. The example below is about calculating a field called basicAdjustedSalary.
BasicAdjustedSalary = 1.06*currentSalary + 2550.00 * age + (yrsOnteam/yrsInLg) *145924.75
Here is a quick example of the issue I am seeing
Current Salary = 4253628.5
Salary Multi = 1.06
Salary Multi * Curr Salary = 4508846.0
*** Incorrect should be 4508846.21
I have all the fields involved defined as float type. I don’t understand why I am not getting the correct result.
Thanks,
Paul
I don’t know if it will be helpful, but here is the code section and the output from the println statements:
** OUTPUT **
Current Salary = 4253628.5
Salary Multi = 1.06
Salary Multi * Curr Salary = 4508846.0
*** Incorrect should be 4508846.21
Age = 34
Age Multi= 2550.0
Age Multi * Age = 86700.0
*** Correct
Yrs on Team / Years in Lg = 0.6666667
Loyalty Multi = 145924.75
(Yrs on Team / Years in Lg) * Loy multi = 97283.17
*** Correct
Basic Adjusted = 4692829.0
*** Incorrect should be 4692829.38
*** CODE ***
//*************************
//Name: calcBasicAdjustedSalary
//Purpose: calculate the basic adjusted salary
//Accepts: void
//Returns: float value representing the basicAdjustedSalary
//*************************
public void calcBasicAdjustedSalary()
{
//Use constants defined in the BaseballTeam class to calculate the
// appropriate value
basicAdjustedSalary = (BaseballTeam.SALARY_MULTI * currentSalary) +
(BaseballTeam.AGE_MULTI * age) + (((float)yearsOnTeam/yearsInLeague) * BaseballTeam.LOYALTY_MULTI);
System.out.println("\nCurrent Salary = " + currentSalary);
System.out.println("Salary Multi = " + BaseballTeam.SALARY_MULTI);
System.out.println("Salary Multi * Curr Salary = " +
BaseballTeam.SALARY_MULTI * currentSalary );
System.out.println("*** Incorrect should be 4508846.21\n");
System.out.println("Age = " + age);
System.out.println("Age Multi = " + BaseballTeam.AGE_MULTI);
System.out.println("Age Multi * Age = " +
(BaseballTeam.AGE_MULTI * age));
System.out.println("*** Correct\n");
System.out.println("Yrs on Team / Years in Lg = " +
((float)yearsOnTeam/yearsInLeague) );
System.out.println("Loyalty Multi = " + BaseballTeam.LOYALTY_MULTI);
System.out.println("(Yrs on Team / Years in Lg) * Loy multi = " +
(((float)yearsOnTeam/yearsInLeague) *BaseballTeam.LOYALTY_MULTI) );
System.out.println("*** Correct\n");
System.out.println("\nBasic Adjusted = " + basicAdjustedSalary);
System.out.println("*** Incorrect should be 4692829.38\n");

The float type is a single-precision floating point number, you are getting the normal precision (about 7 decimal digits) to be expected from single precision calculations. Use the double type if you need more precision, but note that floating point is never absolutely accurate.

How do I open up a URL connection to a website that requires authentication? I successfully opened up a URL Connection to a site (eg www.bloomberg.com) by creating a URLConnection Object. After opening a connection to the site, I parsed the site to grab some information out of it. I did all this in a Java Bean.
Now, I need to open up a connection to a site that requires a UserID and a password? I have the User ID and password. How do I go about doing this?
Please Help
Thanks

To whom it may concern
My name is Monica Marion and I'm the Producer of the Developer channel for ZDNet Australia (www.zdnet.com.au).
I'm currently looking to expand the channel's focus and direction. Part of this expansion involves an increased level of input from the local developer community and we're looking to get a local Java guru on board to write a regular column for us. So I was wondering if someone you know or yourself would be interested in writing something for us?
Could you please contact me at your earliest convenience on monica.marion@zdnet.com.au
Kind regards

I'm a web programmer who doesn't have that much experience with Java. I'm looking to develop an American Football Simulation web application, and I was wondering if anyone knew if it was possible with Java, and if it IS possible, how complicated would it be?
Thanks for any replies.

It certainly would be possible. How difficult would depend on your programming knowledge and on the specification for the simulation. Have you done any Java or C++? If not then it'll be a fairly large task.
