User Enter 5 Digit Number And In Return List Each Number On Their Respective Lines
Sep 16, 2014
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.
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) {

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 I had to create a program that allows the user to enter a day using a number and then enter a year and after they did that it would create an entire calendar for that year ..so I have that but the only issue is I can not get the numbers to line up neatly.how to do the entire thing in loops, I tried a couple in here..what this would look like as loops instead of switches and cases and if else
import java.util.Scanner; public class Calendar { public static void main(String[] args) { Scanner scanner = new Scanner(System.in);
Write a program called ProductCatalog that prompts the user to enter the number of products in the product catalog. The program should then prompt the user for the name and the price of each product in the product catalog. Once all of the products have been entered, the program should output the product information (name and price) of the most expensive product in the catalog. Your solution must use a for loop repetition structure and should use the Product class included in labfiles05.zip to keep track of the product with the highest price. Here is sample output:
Enter the number of products: 3 Enter the name of product 1: iPod Enter the price of product 1: 158.99Enter the name of product 2: iPad Enter the price of product 2: 518.99 Enter the name of product 3: iPadMini Enter the price of product 3: 304.49 Most Expensive: Product [name=iPad, price=518.99]
Your solution should not use an array to keep track of all the product information entered.
I am having trouble with my code, with the For loop and then calling the methods from the Product class into the ProductCatalog. How should I approach this program.
Here is the Product program.
public class Product { private String name; private double price; public Product(String theName, double thePrice) { name = theName; price = thePrice;
[Code]...
Here is the ProductCatalog class where I call the methods from Product class. The For loop is what I am having trouble with as well.
import java.util.Scanner; public class ProductCatalog { public static void main(String[] args) { double number; String product = " "; double productCount = 0;
I am trying to get a user to enter an integer (registration number) between 500 and 5000. if it is below 500 and over 5000 the user should get a prompt "invalid number" and "non-numeric character". See my code below. it is not working when i enter invalid numbers.
import java.util.*; public class Infomation{ public static void main(String args []) { Scanner in = new Scanner(System.in); System.out.print("Student Number:"); int sn=in.nextInt();
So I have this program where i have to prompt user to enter a the value of their savings for n number of weeks (quarters dimes nickels pennies) and the program outputs the total of savings an average of saving per week and an estimation of saving per year.
I managed to do the first step but the problem is that when they enter the value of their savings i don't know how to save the value of each(quarters dimes nickels and pennies) to make the calculations? Here is what i have so far
import java.util.Scanner; public class yearlySavings { public static void main(String[] args) { Scanner kb = new Scanner(System.in); int numberOfWeeks = 0; // initialize value of numberOfWeeks
I am starting a program that is dealing with arrays. My issue, allowing a user to enter 'x' number of people into an array. How do I first allow them to enter the size of an array, and then enter strings (list) into that array. In addition to this, I need to specify the number of boxes of cookies sold by each person and keep a tally of the number of people selling cookies in each category (e.g. 1-10, 11-20...etc). Instead of having a number 100000, I want the user to enter that size, 'x'.
import java.util.Scanner; public class cookie { public static void main(String[] args) { Scanner input = new Scanner(System.in); int x = 100; double saleCount[] = new double [x]; String[] girlScout = new String[100000];
I am trying to write a program that asks the user to enter a number from 1 through 10 and then the program will display the roman numeral for that number.
I am also adding a error message in which i haven't yet because im still trying to figure out how to the program will do the roman numeral.'
I have used the if and else if. but when i input a number it just repeats the number back to me.
The program cimpiles but it doesn't do what i want. here is what i have so far. how can i get the program to display the roman numeral after the number is entered.
import javax.swing.JOptionPane; public class Romannumeral { public static void main(String[] args) { double number;
Write a program called RomanNumeralHelper that allows a user to enter a roman numeral and then outputs the integer number value. Use a Scanner to accept command line input from the user and continually ask for a roman numeral until the user enters Q (or q) to stop. Your solution should NOT use a switch statement.
Here is sample input / output:
Enter a roman numeral [Q | q to quit]: III >> 3 Enter a roman numeral [Q | q to quit]: IV >> 4 Enter a roman numeral [Q | q to quit]: V >> 5 Enter a roman numeral [Q | q to quit]: Q Good Bye!
This is what I have so far in my code, but I cant get what the user inputs when I want it to output the number.
import java.util.Scanner; public class RomanNumber4 { public static void main(String[] args) { // obtain input from command window Scanner input = new Scanner(System.in);
Ok so I have my program working for the most part. In this program I am supposed to take input from the user until they enter a negative number and that works, the problem is that it doesn't work if I enter a negative number on the first prompt. For example if I enter a 100 it would prompt me again and if I enter a negative number it would quit and give me the average, but if I enter a negative number the first time I am prompted the program just gives me an error. How do I fix that?
import java.util.List; import java.util.ArrayList; import java.util.Scanner; public class Application { public static void main(String [] args){ Scanner input = new Scanner(System.in); List<Integer> grades;
Write a method maxOccurrences that accepts a list of integers as a parameter and returns the number of times the most frequently occurring integer (the “mode”) occurs in the list. Solve this problem using a map as auxiliary storage.
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 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.
I have a beginning Java Program I have been working on that creates a number guessing program where the computer guesses a number that the user is thinking of within a certain range. I so far have the program below, but need getting rid of a few kinks/ adding features.
-First, I need to set it up so that the user will be prompted and give a range. It should run and produce something like this:
Welcome to this first-ever mind-guessing program!
Please pick a range (higher than 1 and no larger than 50): 32
You will choose a number between 1 and 32... and I will try to guess it.
With each of my guess, you will tell me whether I am too high (h or H), too low (l or L), match (m or M), or you want to quit (q or Q). My objective is to find the number using as few guesses as possible.
-Second, the game is supposed to give up and restart after failing the five, guesses, but for some reason, after it fails the fifth time, it prompts a fifth guess once again instead, then restarts after- I need to prevent this, so that it should look something like this:
My fourth guess is 17: h My guess is too high?
My fifth guess is 16: h *** I am unlucky this round. I give up.
Let's play!
My first guess is 10: etc..
import java.util.*; import java.lang.Math; public class numguessprac1 { // Declaring variables public static String input; public static int quit; public static int guess; public static int wins;
trying to write a program that takes a user inputted number and converts it to a binary number.
Here's what I have:
package com.java2novice.algos; import java.util.Scanner; public class Converter { static Scanner console = new Scanner(System.in); public void printBinaryFormat(int number){ int binary = console.nextInt();
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.
the number of lines that can be printed on a paper size, the point size of each character in a line, whether lines are double-spaced or single-spaced,the top and the bottom margins of the paper. assume that all characters are of the same point size, and all lines are either single-spaced or double-spaced. note that 1 inch = 72 points. make over, assume that the line are pointed along the width of the paper. for example, if the length of the paper is 11 inches and the width is 8.5 inches,then the maximum length of a line is 8.5 inches.write a program that calculates the number of characters in a line and the number of lines that can be printed on a paper based on following input from the user.
a.the length and width, in inches, of the paper. b.the top, bottom, left, and right margins. c.the point size of a line. d. if the lines are double-spaced, then double the point size of each character
I am trying to make a java code that reads in lines of text and returns the number of spaces in each line.I think i have made it but i can not compile it..
Here is my code:
class Mainh { public static void main( String args[] ) { System.out.print( "#Enter text : " ); String text = BIO.getString(); while ( ! text.equals( "END" ) )
I wrote a java program for my gui number converter app, the main purpose of this program is to make sure that user enters only a binary number for conversion from binary to other number formats. the problem is my program keeps prompting me to enter correct binary number, no matter if i enter correct binary number, it will still keep prompting me to enter correct number. Here is the code
import java.util.*; public class test { Scanner key = new Scanner(System.in); String in; int b; public test()
