Whats The Java Programming Code To Make Accounts With Passwords For Game Maker 7?

From Programming & Design Forum:

Whats the Java programming code to make accounts with passwords for game maker 7? Whats the Java programming code to make accounts with passwords for game maker 7? CZ I'm making an ROG and I would like to have creatable accounts with passwords. i.e: Create an account User name is: BETA TEST and password: beta.

Answer: Basically, you want to have a database that contains user names and hashed passwords. When someone creates an account, make sure the password is complex, hash the password (use a salt), then add the user name and hashed password to the database. When you want to check the password, hash their attempt, then check it against the hash in the database.

I Am Trying To Get A Code With Time Complexity To Show Best Worst And Average Case?

From Programming & Design Forum:

I am trying to get a code with time complexity to show best worst and average case? I have written a java programming code, which is sorting algorithms, the algorithm sorts a random array where the user defines the length and the range of that array, this then displays the running time of the algorithm in nanoseconds however I need under that to display the Best, Worst and Average case time in nanoseconds also known as time complexity I have searched go ogle Viki yahoo to find answers but nothing, I know the big Oh-Notation.

Answer: Yahoo answers is not the place to ask about sorting algorithms, however intelligent and reasonable the question may be. Asking on forums specifically about java and programming would be most suitable. Yahoo answers is where people go to ask "UMMMMMMM.... I THINK I'M PRAGNET" and "WIFI PROBLEM, HELPPPPPPPPPPPP!!!!!!!!!!!!!" Sometimes you'll get the question like "When sub netting a network, which of the following is a netmask?" which was clearly ripped from a homework assignment, and the person asking believed that they'd get a response in a few minutes. You could also try Redd it. But not Yahoo answers.

What Is The Have Code For Shutting Down A Computer?

From Programming & Design Forum:

What is the have code for shutting down a computer? Java programing code for shutting down a PC

Answer: There is no standard "pure" Java way to do this. The easiest way would be to use Run time.exec() to invoke the local shutdown command. This will not be portable. You could also use JENI to use the low level APO to achieve the same thing. Again, not portable. The shutdown code will be something like try { Runtime rt = Run time.getRuntime(); Process PRC = rt.exec("shutdown -l"); } catch(Throwable t) { t.printStackTrace(); } Once the shutdown logic is solved, make the shutdown command logic available over RIM. This is trivial and the best advice I can give you is to follow the RIM tutorial: http://java.sun.com/docs/books/tutorial/rmi/

How Do You Make Two Windows Simultaneously Update In Java Programming Code?

From Programming & Design Forum:

How do you make two windows simultaneously update in Java programming code? Please add some examples if you have them. Thanks!

Answer: You're going to need to use multiple threads. Make sure you're updating the windows in the event dispatch thread(EDT) from your threads. If your GUI appears to "freeze" when performing calculations, that is because you are preforming work on the EDT. Code... Well... It's going to be a lot of work for me to write all that code for this example, but see my sources below to the Sun Java tutorials.

A Java Programming Coding For A Candy Machine To Sell About Four Items?

From Programming & Design Forum:

a java programming coding for a candy machine to sell about four items? A candy machine has been purchased for the UCLA Grocery store, but it is not working properly. The machine sells candies, chips, gum and cookies. You have been asked to write a program for the candy machine so that it can be put into operation.The program should do the following. 1. Show the customer the different products sold by the candy machine 2. Let the customer make the selection 3. Accept money from the customer 4. Release the item * Identify the problem and perform the analyses

Answer: wow, tony...a complicated convoluted language?.. you must be a vb "programmer", java is a very hold your hand language, and this object oriented design extends itself very EASILY to a language like java. a language like C++ is probably borderline straight binary code huh tony? ok you need to read your textbook or whatever you've learned but it will go something like this create either a set or an array of strings inside your main class (grocery store) that will be your products. create a method called displaySelection() which will enumerate all the 'products' you have (using a for loop and an array is best). have a method getSelection() that gets user input (getting user input should be easy enough to google). as for payment, you can do this in a number of ways, the most efficient is probably to create a hash table rather than an array for your products, BUT to keep it simple have one array be strings of products and another be a float array of product prices, and then have the prices match for instance the price of product[0] ("gum") will be prices[0] (0.75). then ask for payment with user input and make sure it is enough, if so then release the item. this can easily become more and more advanced (or 'complicated and convoluted' for noobs) by adding additional classes like a customer class who has a set amount of money, etc. but this is a simple mock up.

Round Up Payment Amounts To The Th's In Java?

From Programming & Design Forum:

Round Up Payment amounts to the Th's in Java? Am having trouble figuring out where to put a code in to round up payment amount and indentures rates in a mortgage calculator Java program code. I have figured out how to get the math in formula and the calculator works, I just can't get the output to read as rounded up and to the Th's. ( i.e. 0.00 )

Answer: First, that would be rounded to the hundredths. For accurate math with rounding, use java.math.BigDecimal. For example: String as String = "101.235"; BigDecimal value = new BigDecimal(asString); BigDecimal rounded = value.setScale(2, Big Decimal.ROUND_HALF_UP); System.out.println(rounded);

Compile And Run Java Code Online?

From Programming & Design Forum:

Compile and run java code online? I'm currently trying to work on some basic java programming code. I'm working on a public computer and I'm unable to install any java compilers on this computer. I went to command prompt and typed "java" and it doesn't seem to have the compiler installed. However, I have access to Internet. Are there any free on line compilers I can use to compile my ".java" programmes and run and see the output?

Answer: If you can bring a flash drive (or CD) and plug it in, then maybe there's a chance. The JFK doesn't need system Dells or registry entries to run. (Assuming windows here, because macs have java and JFK installed by default.) You'll also need permission to run a command prompt, and access to a text editor. A web search for "portable java" turns up a bunch of hits. This one looks promising: http://www.pendriveapps.com/portable-java-run-java-from-a-flashdrive/

Java Programming Code For A Computer To Generate Certain Characters?

From Programming & Design Forum:

java programming code for a computer to generate certain characters? can anyone give me an example java coding answer for this game; get input from user as player 1 either p(paper), r(rock) or s(scissor). the computer as player 2 will generate either p, r or s. the rules: paper dominates rock, rock dominates scissor and scissor dominate paper. the winner will be either the user, computer or a tie. (please help me!!)

Answer: public class Turn { int sign; public Turn { new_sign(); } public int new_sign() { sign = (int) (Math.random()*100)%3; return sign; } public string toasting { if ( sign == 1) { system.out.println ( " computer plays rock! " ); } else if ( sign == 2) { system.out.println ( " computer plays paper! " ); } else if ( sign == 3 ) { system.out.println ( " computer plays scissors! " ); } } } public class stream ( download this class from the Java APO - it's a simple in-out class, pretty handy to have. ) // next class public class Main { public static void main ( String[] Argos ) throws IO Exception { Main main = New Main; _main.go(); } public void go() { char player; system.out.println ( " [R]ock, [P]aper, or [S]cissors, please press the corresponding letter now " ); player = Character.toUpperCase(in.readChar()); system.out.println ( " you chose " + player ); Turn turn = new Turn; _turn.to_string; if ( player == R && sign == 1 ){ system.out.println ( " rock draws with rock! " ); } else if ( player == R && sign == 2 ) { system.out.println( " paper beats rock, you lose! " ); } else if ( player == R && sign == 3) { system.out.println( " rock smashes scissors, you win! ") } else if ( player == P .... // continue the If-else if statements until all possibilities ( //there's 9 of 'em ) are filled.
