How To Import TXT File That Has Color And Four Digit Number
Apr 10, 2014
I am trying to figure out how to import a txt file that has a color and a four digit number. Everything that I have tried comes up with some kind of error.
I couldn't find an edit button. I need to store the String and int from the txt file into an array. The problem that I keep having is that the compiler seems to want it as either two ints or two Strings.
1. Write a Java program that randomly generates a five-digit lottery number and prompts the user to enter a five-digit number. Each digit in the number is in the range between 0~9. The program should determine which prize the user wins according to the following rule:
- The user wins the first prize if the user input matches all five digits in the lottery number in exact order. -The user wins the second prize if the user input matches any four digits in the lottery number in exact positions. -The user wins the third prize if the user input matches any three digits in the lottery number in its exact position. -The user wins the fourth prize if the user input matches any two digits in the lottery number in its exact position.
- The user wins the fifth prize if the user input matches any one digit in the lottery number in its exact position.here is my code. I have tried replacing the && statements with || and it always returns either case 1 or case default.
import java.util.Scanner; import java.util.Random; class Hw5 { static int getPrize(int g1, int g2, int g3, int g4, int g5, int u1, int u2, int u3, int u4, int u5) {
So I am currently writing my first assignment and have run into problems with my coding. The task was to have someone enter a 5 digit number and in return, I list each number on their respective lines. We also must create an error if a number other than 5 digits was entered. My problem is that when they enter a 1 or 2,3,4,6,7,8 digit number.. the error message occurs along with the rest of the messages (listing the numbers, etc). I want the program to end (or even re-ask to enter the numbers) if they incorrectly enter the data.
i have tried permutation with big Integer in Java. it works fine upto 4 integer input say 3456 P 2345 but nothing happens in console when i type 5 digit input..here is my code
public class cvic { public static void main(String[] args) { Scanner scan = new Scanner(System.in); System.out.print("Enter n and r: "); BigInteger n = scan.nextBigInteger(); BigInteger r = scan.nextBigInteger(); System.out.println("nPr = "+fact(n).divide(fact(n.subtract(r))));
But my requirement is inputMask should take no limit no. of digits(only).but it is taking no. of 9 which i have given in mask attribute..
And if i am not giving mask attribute and i am handling with keyFilter(....regx) but it is allowed to paste alphabetic(Char) also. so mask attribute is required.
I'm trying to output a ten digit phone number as a string on one file, and write another program to write it as a long because I don't know what value I need to use in order to get the code to run properly on either one.
I have to write a program that inputs a 5 digit integer from the keyboard and prints if the input number is a palindrome or not. I got it to work, but when my result prints it says "0 is a palindrome" or "0 is not a palindrome". How can I get rid of the 0 and replace it with the number input by the user?
import java.util.Scanner; public class Palindrome { public static void main(String[] args) { int number; int digit; int temp;
How do I compare an array (or maybe int?) (example: 3572) to a 4digit number from random generator? how many of the four digit match the generated numbers.
I am new to java programming and using bluej for programming and i have tried this question what i have have given in title ... how to find out the errors in the following program:-
class Primedig { public void getinput(int n) { int ctr=0; while(n!=0) { int r=n%10; for(int i=1;i<=r;i++)
[code] .....
output:-
For example input is 243 the output comes only 3 not 2& 3 both.

and here is my code. I cant get it to print the right statements.
import java.util.Scanner; import java.util.Random; class Hw5 { static int getPrize(int g1, int g2, int g3, int g4, int g5, int u1, int u2, int u3, int u4, int u5) { //code for determining the prize comparing (g1, g2, g3, g4, g5) to (u1, u2, u3, u4, u5) if (u1 == g1 && u2 == g2 && u3 == g3 && u4 == g4 && u5 == g5)
So im trying to make a coin flip game in java. Im relatively new to the language and the only other language i knew was javascript so im still learning. Ive already made one before using just one class and putting all the code inside, but im now trying to do it with methods since im trying to learn them. The basic idea of the game is that the user picks how many coins they'd like to flip, they pick heads or tails, then the computer flips the coins and calculates if there was more heads or tails to tell the user if they won or not. Im not quite complete with the program as you can see but ive already run itno an error. I was just doing some tests on the code i already have and i found that when i call the method settingUpCoin in my main class the program terminates. So basically, when i run it, it executes userImp right, transform right, but then it dosent let you enter a value for howManyCoins and terminates before you get to settingUpCoin.
(Notes: this was all done in eclipse luna build or the java ide. The class files are all separate in the actual thing i just put them together here to demonstrate my code.
import java.io.IOException; public class Coin { double myCoin; int numOfCoins; int counter; double arrayOfCoins[] = { };
I am trying to write a program, which includes an import data option. This option is used to import information from a text file.
The data is read from the file and objects are created and added to the student's record (The text file contains some information of the courses that the student is taking).
So my question is, how do i import information from a text file ?
and after they are imported, how do i create the objects in order to add them to the student's record ?
I would like to build a GUI where by I can import a text file and interrogate certain values and then display them in a window. Thing is I would like to know what window type that will support this. i.e Panel,internal frame,dialog box.. etc etc... I am using Netbeans.
Label is not a valid type., TableView is not a valid Type., etcera
This exception I then solve with placing an import tag inside the .fxml file.
However as I do not know each import name, I have to look this up like writing down:
Label label = new Label();
inside a class and then place my cursor on it to see which import name Eclipse generates.
This import name i then put inside the .fxml file with <? import ?> beginning and end tags with question marks around it.
Is there anyways to automatically generate these import tags inside an .fxml file even if you don't know the import name for the control you want to use?
How to import data from a file using Object Oriented Programing? I know how to write OOP Java and I know how to read data from a file in Procedural Java but would like to know more about how to do it OOP. Is it the same as reading data process as in Procedural programming?
No problem setting background color for layouts, e.g. bdrPn.setBackground(new Background((new BackgroundFill(Color.BLACK, CornerRadii.EMPTY, Insets.EMPTY))));
But neither of the following are working for me, running JavaFX 8 on latest OS-X
scene = new Scene(bdrPn, winW, winH, Color.BLACK); scene.setFill(Color.BLACK); scene.setFill() worked fine for previous versions of JavaFX.
I've just started working on a program and i'm already having difficulties with the program. I can't get the background color to change from the basic gray color. Maybe you can tell me what i'm doing wrong.
import javax.swing.JFrame; import javax.swing.WindowConstants; import java.awt.*; import java.lang.Object; import java.awt.Color; public class FrameDemo{ public static void main(String args[]){ Toolkit toolkit = Toolkit.getDefaultToolkit ();
[Code]...
also if theres any way to shorten up what I have there, that would be great.
If I want to read from file the word "red" And then the following is not the right way like in the code ,, How to set the Color name
File inputFile = new File ("C:\input.txt"); Scanner scan = new Scanner (inputFile); String RedColor=scan.nextLine(); Color backColor = new Color(redColor);
which method i can use so that the program checks if the input value is a digit or else outputs a message saying that `the value entered is not a number.
I am having a problem of how to write a program dat will input one number consisting of five digit,separate the number and print the digits separated from one another by three spaces each.. I tried to use divisional and remainder operation but it didn't work.
I have to write a program that asks the user to enter an integer and then the program is supposed to display the integer each time with the rightmost digit dropped off. For example if the user enters 1048576 the program would display 104857 10485 1048 104 10 1 and 0. this is what I have so far
import java.util.*; public class Lab5 { public static void main(String[] args){ Scanner input= new Scanner(System.in); System.out.print("Enter An Integar Value: "); int number = input.nextInt(); while (number != 0){ number = number / 10;} System.out.println(number); } }
I am not getting any errors, however when i run the program and supply an integer it skips displaying all the integers in-between and automatically displays 0.
I need to know how many four letter strings I can generate that begin with the letter "v". Now I had been testing many ways to do this but anm stuck. I can generate a single line up only a certain amount. I need it to continue till it reaches the max number. So since it needs to always start with V i eliminated the need for four and only a 3 letter string.
package javaapplication4; import java.util.Random; public class JavaApplication4 { /** * @param args the command line arguments */ public static void main(String[] args) { Random r = new Random(); int c = r.nextInt(26)+ (byte)'a';
