Validating User Input

Oct 16, 2014

My project is a program that uses methods to display strings in a variety of different ways. I already have all of that working, my problem is checking for user inputs.For example on the menu portion of my program i ONLY want the user to input 1-5.here is the method i developed for checking user input IT DOES CONTAIN ERRORS this is where i am having troubles.

public static int checkInput(String prompt, int lowerBound, int upperBound) {
int input = 0;
boolean done = false;
while ( !done )
{
System.out.println(prompt);
if (input.hasNextInt())

[code]....

here is the rest of my program which is working fine besides the checking input. i would like to implement this method for checking inputs into all places where the user is asked to input something.

import java.util.Scanner;
public class DisplayingStrings {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int getNum = checkInput("Enter #(1-5)", 1, 5);
System.out.println("--String Writer--");
System.out.print("Enter a string: ");
String word = input.next();
displayMenu(word);

[code]....

Validating Input Using HasNextFloat

Jan 22, 2015

I am trying to make sure that the input is a float but not a string or character. I tried using hasNextFloat in a do-while loop but when a character is entered it won't re-prompt the user for input. It kind of just stops.

public class LabAssignment1 {
public static void main(String[] args) {
float num1, num2, result;
int choice;
Scanner scan = new Scanner(System.in);
DecimalFormat df = new DecimalFormat("#.###");

Calculate Factorials Of Numbers 1 Through 10 - Validating Input

Sep 13, 2014

I'm trying to write a program that calculates the factorials of the numbers 1 through 10, based on user input... My problem is that I don't know how to address the possibility of the user entering something other than a number. When I test the following code by entering a letter, I get an Input Mismatch exception. I'd like to be able to inform the user that the entry is invalid, and ask for another response. Here is my program thus far:

Java Code:

import java.util.Scanner;
public class Factorial {
public static String entryString;
public static char entryChar;
public static Scanner input = new Scanner(System.in);

[Code] ....

Validating The Contents Of A File?

Oct 21, 2014

I have the assignment of making an application that reads a file and then validates the contents to create a statistical report.

I have managed to have the application read the contents but im completely puzzled on how the validating works.

Is there coding in the file that put the numbers and words into the correct data types or is that also done in the application?

The application is to read the file of rugby scores and the produce the report with the amount of goals scored.

Asking User For Input Twice?

Apr 19, 2014

I'm working on creating a dice game and getting the users input is giving me a really hard time. I have the main game working but this part I'm stuck on. The problem is that it's not giving me the chance to enter the second input when I ask for the game.

//Create Scanner object
Scanner keys = new Scanner(System.in);
//Get chips

[Code]....

*****This is what I get when I run it

run:

How much money would you like to change? 50

You now have $50 in chips.

What game do you want to play? You did not pick dice.

Formatting User Input

Feb 4, 2014

I have been given a piece of work to do for College that requires me to format user input. For example: This is an example of text that will have straight left and right margins after formatting

will transform into:

This..is..an.example
of..text..that..will
have..straight..left
and...right..margins
after.....formatting

The user inputs the width, in the case above being 20. Each line has to therefore be 20 characters long. All spaces are to be replaced with full stops.

This.is.an.example.o
f.text.that.will.hav
e.straight.left.and.
right.margins.after.
formatting..........
public class Main {
public static void main ( String args[])

Value Will Multiply By User Input

Apr 14, 2014

I would like to multiply the amount stated inside program by user input. I currently have

public static void setTicket(double ticket)
{
//if statement for tickets
if (ticket == 1)
Ticket = 10.00;
else if (ticket == 2)
Ticket = 20.00;
else if ( ticket == 3)
Ticket = 30.00;

The user should enter 2 and the value should show 20.00. This does work however im looking for a way to say enter 2 = 2*10 instead of stating each value individually.

If Statements And User Input

Dec 12, 2014

I am new to java and I am trying to write a program where someone has to guess the number. The correct number is 3. If they are below three. It tells them that they are too low and to guess again. If they are too high, it tells them they are too high and to guess again.

However, I am having problems once they enter a number and they get the response "The number was too low. Try again" as it lets them try again but doesn't tell them if it's right, wrong, or too high. I'm not sure what piece of code I am missing. Here is what I have so far:

import java.util.Scanner;
public class Guessthenumber {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter a number between 1-10.");
double value = input.nextDouble();
if(value == 3)
