Technically, when you run the program, a gif page appears (that I put as a placeholder) and when you press the letter 'n' JCreator runs the program, displaying a character P on a .txt field made using the Notepad on Windows. You can move it left, right, down, and up andf it will move accordinly. However, each time I make such action, the compiler has to rewrite to whole .txt field with the new position.
My former tutor said that in order for it to be "real-time", we have to use an applet.
The idea behind this program is that the program prompts the user to input an initial base (2-36), which checks to ensure that it is a valid int, then asks for a number to convert (which is taken as a String), then it asks which desired base the user would like to convert said number to. I have a basic program that is not complete, but allows me to do a few conversions using convertTo. I believe that I am going to have abandon this method and try mathematically converting every number. This leads me to what I can and cannot do. I am unable to use the initialBase as a condition to know what kind of number i an converting. For instance, I don't know how to make program know that if "2" is the initialBase, that that means that the String is a binary number. THAT is what I'm having problems with.
Here is my initial program that has a few things that are copied and pasted from other bits of my code in my program:
XML Code: Url...
I have broken down what I (think I) need to do here: Check to see if the input base is 2, 8, 10, 16, or 32. Hint: Put the possible bases in an array, and check the input base against the array. Check to see if the input number is valid for the base. Hint: Create a String "0123456789ABC...V" and compare each input character with the first "base" characters of the String. Check to see if the output base is 2, 8, 10, 16, or 32. Hint: Use the same possible bases array you used in step 1 to verify the input base.Check to see if the input base is equal to the output base. If so, print the input number. Perform a conversion from the input base to base 10. Perform a conversion from base 10 to the output base. You do this in 2 steps because it's easier to check each conversion separately.Output the converted number.
I am trying to write a program for converting positive binary inputs into hex.Why am i getting this errors while compiling my binary to hex converter..
Exception in thread "main" java.lang.NumberFormatException: For input string: "148.0" at java.lang.NumberFormatException.forInputString(Num berFormatException.java:65) at java.lang.Long.parseLong(Long.java:441) at BinToHex.convertbintohex(BinToHex.java:24) at Test.main(Test.java:4)
Here is my BinToHex class
import java.io.*; public class BinToHex { double tempDec,fractionpart; long longofintpart,templongDec; String inpu ="1001.01"; String hexOutput,intpart,tempDecString,hex = null;
I am trying to write a program converting Fahrenheit to Celsius using a for loop. I get it to run and Fahrenheit goes to a hundred. My issue is that the Celsius just says 100 down the column and is not converting. I have tried messing with it, and can not figure what is wrong with it.
import java.util.Scanner; public class Controlstatement { public static void main(String[] args) { double F = 1.0; double Celcius = 100; System.out.printf("%s%20s", "Farenheit", "Celcius" ); for (int Farenheit = 0; Farenheit <= 100; Farenheit++) { F = Celcius * (Farenheit - 32 * 5.0/9.0); System.out.printf("%4d%,20.2f", Farenheit, Celcius); } } }
I have been writing the below Dinner Menu Applet; however some text is not showing on the applet and it is not adding the 'desserts" section correctly especially the one that says "rice Pudding". I've tried it in so many different ways and it's sill not working correctly.

I'm converting from ASP to Java for a legacy site. I believe the first part of the if statement is right but I'm having an issue within the else staetment. I'm getting date is undefined, I've tried using getYear and getDate but have not been successful.
ASP:
If Request("action") = "results" Then aMonth = Request("selMonth") aDate = cint(Request("selDate")) aYear = cint(Request("selYear")) Else aMonth = UCase(MonthName(Month(Date()),true)) aDate = Day(DateAdd("d",-1,date())) aYear = Year(Date()) End If
I try to use below codes to convert Hex String "1111737999630745" to ASCII.
When I read the result in Notepad++ with HEX-Editor plugin, I find attached image which is different from above String, there is one additional c2 and I am quite confused.
Java Code:
public static void main(String[] args) throws IOException { Test strToHex = new Test(); File file = new File("D:/filename"); // if file doesnt exists, then create it if (!file.exists()) { file.createNewFile();
I was reading about the char data type in Java. I know that an unsigned 16 bit integer is used to represent a char. So we can write the assignments below:
char a = 65; // a will get the value 'A'
But the limit of the char value is 65535.
So I've tried out a few things with char and trying to understand them but I'm not sure how they work.
char a =(char) 70000; char b = (char) -1;
In the first case I thought that 70000 % 65535 would happen internally and the unicode character present at that location would get stored in 'a' but if I do that I get the answer of 70000 % 65535 as 4465. But when I display 'a' it shows me the output as '?'. Clearly '?' isn't at 4465.
In the second case I have no clue what's happening but somehow when I display 'b' it shows me '?' again.
i have created a frame with a menu bar displaying contents..now i want to set a username and password to that flame through an applet how to add applet to the frame??
here is my code ..
import java.awt.*; import java.awt.event.*; import java.applet.*; class MenuFrame extends Frame{ String msg=""; int flag=0; CheckboxMenuItem debug,test;
I am facing problem when displaying my applet on jsp. I have convert my applet project into CustomColor.jar. my package is dcs.raj.MyApp
I have import my jar into project property. But still it is showing error on all browser, i have changed the java control panel > Advanced > Java Consol > Show console.
Here is my code, basically I'll tell you what my program is suppose to do, I want to be able to leave the text box's empty if I like I want to skip 1 or more or all if I like skipping just basically means 0 but getting this error, it's forcing me to type in them all.
Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: "" at java.lang.NumberFormatException.forInputString(Unk nown Source) at java.lang.Integer.parseInt(Unknown Source) at java.lang.Integer.parseInt(Unknown Source) at StockControl.addToStock(StockControl.java:86)
I have this project due and its asking that i print out what type of triangle it is when the user inputs 3 sides. I have most of it done and working, but it pops up different windows instead of using one window for everything. The assignment says it needs all the final info to be in one window. The boolean is coming from another method. I'm unsure how to get it into a string (Or if that's what i have to do). The method must return a boolean true/false.
import javax.swing.*; public class Triangle { public static void main(String[] args) { int side1 = getSides(); int side2 = getSides(); int side3 = getSides();
In my Java class, the last assignment we had to turn in was to create a program that would take a users input and create a new type of animal. I went through the different steps in the instructions, and everything seemed to be going well up until the point where we actually took the users input and created the new animal. Specifically, I kept getting an error stating that I could convert a String to an animal.
I'm attaching the main class (Animal), one of my animal classes (Bird) and the class where I'm getting the error (AnimalStuff). I turned the program in as is, so what's done is done, but I'd like to learn what I'm doing wrong and what I can do better. I do know that the loop in AnimalStuff is wrong as it doesn't work right either, but I'm more concerned about the conversion from String to animal, as the entire program depended on this to work, and it doesn't.
public class Animal { /** * @param args the command line arguments */ public static void main(String[] args) { } public static String kind; public static String integument;

Is there anything that jumps out at to what I'm doing absolutely wrong?
I've started writing a new program that Scans for some strings. I want to specify a random Integer to those Strings in order to do my desired idea. what should I do?!! my codes are here :
import java.util.Random; import java.util.Scanner; public class Draw { public static void main(String[] args) { System.out.println("This Program is written to solve little problems in families cause of doing unwanted works!!");
[code].....
now I want to Specify an Integer to each person that has been scanned! for example if the first person is " David " , which is a String, in the next step :
Random randomNumber = new Random(); randomNumber.NextInt(101); int David = randomNumber.NextInt(101);
I'm trying to complete a code to convert decimal to octal. however i can't figure out how to print the output correctly. it should be.. Your integer number 160000 is 0470400 in octal. (160000 is the number you input). My code is...
Scanner input = new Scanner(System.in);
int value; int a; int b; int c; int d; int e; int f; int g; String result;
[Code] .....
Lastly, my output prints everything correctly, but the input number always is 0.
Ex error: input= 160000
Your integer number 0 is 0470400 in octal.
it should be.. Your integer number 160000 is 0470400 in octal.
I am taking Python this semester. Our teacher wants us to convert Python to JavaScript without really explaining how or/and expecting us to be familiar with it already.Python Program I have is pretty simple - it prompts you to enter your first and last name and end your DNA string, "CAG" repeats are counted by another function and the result is passed to function that identified weather you may have huntington's decease or not.
<body> <p>Enter First Name: <input type="text" size="25" id="firstname" value=""> <p>Enter Last Name: <input type="text" size="25" id="lastname" value=""> <p>Enter DNA: <input type="text" size="25" id="DNA" value="" > <p><button onclick="alertt(f,l,d,c,p)" style="background-color:pink"><b>PRESS TO FIND OUT RESULT</b></button></p> <script>
[code]...
When I run it there is an issue with countCAG and prediction functions :( I would run each one individually in JS console and I get Undefined, or InvalidString I read that I am supposed to use var in front of each variable, unlike in Python where you just assign variable a value without any add-ons in the front. But JS console seems to recognize both ways of assigning, however var smth=0 immediately evaluates to Undefined, and smth=0, gives me 0...
I compiled a java program and converted it to an exe file and it works fine on the computer I created the java file in but when i try it on another computer it gives me a "Java Virtual Machine Launcher - A Java Exception has occured" error message.
