Java Program That Randomly Generates Five-digit Lottery Number And Prompts User For Input
Sep 25, 2014
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.
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)
[code]....

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 been struggling with this program for weeks. This program is supposed to take a user's inputted odd number and then print out all prime numbers lower than that number.
public class PrimeNumber
{
Scanner scan = new Scanner(System.in);
int userNum;
String neg;
public void getUserNum()

I wrote the following code for a lottery game. The problem comes when I run it. If one number of a 3 digit number matches, it's supposed to print "you win 1000" But regardless if a number matches or not, it says "sorry, no matches" ...
import java.util.Scanner;
public class Lottery {
public static void main(String[] args){
//generate lottery number
int lottery = (int)(Math.random() * 1000);
//Prompt the user to enter numbers
Scanner input = new Scanner (System.in);
System.out.print("Enter your numbers (3 digits): ");
int guess = input.nextInt();

So I was going to try to create a program that prompts input and creates a file (That didn't exist before) with that input as name.Then, the program prompts inputs after stating questions such as 1 + 1, then if the user inputs an answer, put "Question # = Correct "or" Wrong.Code SO Far:
Java Code:
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
public class File_Read {
public File_Read() {//File_Read is the Interactive object
[code]....
So that it puts the Correct or Wrong into the file.

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]...

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 {

So i need to write a program that prompts the user for 3 double numbers x, y, z that outputs 2x^3 + 3y^5 + 3x^3y^2 +xyz with
(1) 4 digits precision
(2) with a ',' to separate thousands
(3) all digits of the result including the precision are put to 20 positions (from right to left)
I am not really sure what it is suppose to look like or how to start it.how to mix Math.pow with multivariable and printf.

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;

so I had to make a program that prompts the user to enter a loan amount and the years for the loan and I have the conversions and everything my only issue is that when the chart pops up it just looks like a bunch of numbers and its missing the column headers
for example
Interest Rate Monthly Payment Total Payment
import java.util.Scanner;
public class InterestRate {
public static void main(String[] args) {
double monthlypayment = 0;
double totalpayment = 0;
Scanner input = new Scanner(System.in);
System.out.println("Enter Loan Amount");

Write a java program that will ask a user to input grades until the user inputs the sentinel value -1. The program should test each input to determine whether 0<=grade<=100. If the grade entered is within this range, the program should print "Grade accepted;" if not, the program should print "Invalid input".

Write a program (TwoIntegers.java) that prompts the user to enter two positive integers and prints their sum (by addition), product (by multiplication), difference (by subtraction), quotient (by division), and remainder (by modulation). When the user enters 5 and 3, the output from your program should look exactly like the following:
Enter two positive integers: 5 3
The sum is 8.
The product is 15.
The difference is 2.
The quotient is 1.
The remainder is 2.
import java.util.Scanner;
public class TwoIntegers {
public static void main(String[] args) {
System.out.println("Enter two positive integers: ");
Scanner userInput = new Scanner("System.in");
int integer1 = userInput.nextInt();
int integer2 = userInput.nextInt();

I have this program where I'm supposed to fill an array with 1000 indices with 1000 randomly generated numbers between 1 and 1000. The program is supposed to check if any of the numbers match an index that is the same value (so for example, the number 4 is in index 4). How to check for that condition, especially using a binary search (I'm also told to use a binary search).
Right now the variable index isn't initialized because I don't know what to initialize it to exactly. How do I check to see if any numbers match the value of the same index?
import java.util.*;
public class Identity {
public static void main(String[] args) {
int [] integers = new int [1000];
// Fill array with randomly generated numbers
int [] display = GenerateRandom(integers);

Write a program that prompts the user for an input number and checks to see if that input number is greater than zero. If the input number is greater than 0, the program does a multiplication of all the numbers up to the input number starting with the input number. For example if the user inputs the number 9, then the program displays the following sum:
9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 362880
That's the question I'm getting and so far all I've got is
import java.util.Scanner;
public class Lab4Q3
{
public static void main (String[] args)
{
int keyboard;

Sample
enter a string for password: wewewx
valid password
It's being graded on

My current issues with the current code I have written is simply the password doesn't work unless it starts with 2 digits, the other order it displays as wrong. and I have no idea how to add a GUI.

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;
[Code] ....

I tried the following code, OK:
Java Code:
String temp = "hi this sf hello is new what is this";
String[] cmd = temp.split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');
However, when i get the input from user , i didnt get the expected result:
Java Code:
System.out.println("Enter the input string to count the words: ");
String[] cmd = new Scanner(System.in).next().trim().split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');
Now Result for above code:
Enter the string to count the words:
hi this is new
words are: 1

Part A: While Loop Program
Write a program that detects Fibonacci numbers. Prompt the user to input a positive integer. Upon input, the program will determine if the number is either a Fibonacci number or not. If a Fibonacci number, then the order of the number in the sequence must be output. If not a Fibonacci number, then the Fibonacci numbers above and below it (including their order in the sequence) must be output. Once it finishes, the program will prompt the user for a new number. The program will exit if the user enters a string (such as “quit”) instead of an integer. Use the sample output file, fib-seq-det.txt, to view a sample session
This is my project, I wrote a programs that tells you if the input number is a fibonacci number or not. For some reason it only works for some Fibonacci numbers but not all of them.
import java.util.Scanner;
public class While
{
public static void main(String[] args) {
System.out.println("Welcome to the Fibonacci Sequence Detector
");
Scanner in = new Scanner(System.in);
System.out.print("Please input a number for analysis: ");
int input = in.nextInt();
