Java Lotto - Randomly Generate Five-digit Number And Prompts User To Enter Five-digit Number
Sep 25, 2014
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) {
[code]...

//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 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.

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;
[Code]...

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.
import java.util.ArrayList;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.Scanner;
import java.util.InputMismatchException;
[Code] ....
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 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;

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;

Create a Java application that prompts the user to enter their personal details: First name, last name, gender, address, suburb, postcode, and phone number. Then the program displays all of your personal details to the screen as illustrated. Name the file PersonDetails.jav
package exe
import java.util.*;
public class Review2 {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter your full name: ");
String name = scanner.next();
[Code]...
If you cant tell straight away how i have stuffed up, what is happening is this;
When i am promoted to enter my name, 'John Smith'. The word 'John' would be stored in the name variable, while 'Smith' is stored under gender, so the next prompt is then 'Whats your address?'
So its only assigning one word per variable, now as far i understand, a string should not work that way. So where is my mistake?

I wrote a little piece of code like so:
public class Oott
{
public static void main ( String[] arguments)
{
System.out.println( 1.0 / 13.0);
}
}
When I run this it prints out "0.07692307692307693". Is that an error? Rounded correctly it should be "0.07692307692307692", shouldn't it? The repeating series is "076923". Do the Java specs allow a value returned that's off in the least significant digit?

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;
