Output Min And Max Numbers The User Enters - Storing Value
Jul 17, 2014
I need to receive input from the user, as many times as he wants. tha is done with the while loop. I also need to output the min and the max numbers the user enters, therefore i have the if statememnts. also if the user enters only one value i need to output that one value as the min and the max.
int min =0;
int max = 0;
int option = JOptionPane.YES_OPTION;
while ( option == JOptionPane.YES_OPTION){
String dataString = JOptionPane.showInputDialog("Enter an integer");
int data = Integer.parseInt(dataString);

So I'm attempting to have this program take the users input of integers, pressing enter in between each one. If they enter a negative number it lets them know that its invalid. At the end of the program it takes all of the valid integers entered and must add them and average them. I've put the final println in there as a placeholder. If the user types in "6" then presses enter and types in "3" , the output is:
There were 3 valid numbers entered.
The sum of the valid numbers was --- and the average was ---.
There were 0 invalid numbers entered.
It then continues on allowing the user to enter more values. Here is the example output for correct code"
Enter a positive value (EOF to quit): 4
Enter a positive value (EOF to quit): 7
Enter a positive value (EOF to quit): 8
Enter a positive value (EOF to quit): 2
Enter a positive value (EOF to quit): -1
The number "-1" is invalid.
Enter a positive value (EOF to quit): 8
Enter a positive value (EOF to quit): 0
Enter a positive value (EOF to quit): -4
The number "-4" is invalid.
Enter a positive value (EOF to quit): CTRL-D
There were 6 valid numbers entered.
The sum of the valid numbers was 29 and the average was 4.83.
There were 2 invalid numbers.

In my computer science project the program has to end if the user enters 0 as his choice from a menu given to him, so how would I go about ending the program.

My question is how can I make the program repeat until the user enters the number 4 to exit?
/**
* Write an application for a furniture company; the program determines the price of a table. Ask the user to choose 1 for pine, 2 for oak, or 3 for mahogany. The output is the name of the wood chosen as well as the price of the table. Pine table cost $100, oak tables cost $225, and mahogany table cost $310. Also ask the user to specify a
(1) large table or a
(2) small table.
Add $35 to the price of any large table and add nothing to the price for a small table. Display the output. Your program must repeat until the user chooses to exit.
*/
import java.util.Scanner;
public class Wood {
public static void main(String[] args) {
Scanner input = new Scanner (System.in);
System.out.println ("Table Prices");

I'm trying to do a user validation loop that runs until the user enters a valid binary, q, or Q. I think the rest of my program should work as intended, but here is the areas of concern:
public static boolean isBinary(String num) //Check if the entry is binary
{
for(int i = 0; i < num.length(); i++) {
if(num.charAt(i) != 0 || num.charAt(i) != 1){
return false;
[Code] .....
The program runs without errors otherwise.

In my cs class, we have to write a program that throws an exception if the user enters a negative number, the program should prompt the user to enter only positive numbers and then let them retype the number. But everytime I throw an exception, my program gets suspended.
What am I doing wrong, or is there no way to continue a program if an exception is thrown? Does the program automatically get suspended when an exception is thrown?
try{
do
{
N = kb.nextDouble();
if(N<0) {
throw new NegativeArraySizeException();
}
else
j++;
}
while(j==0);
fill.size(N);
}
catch(NegativeArraySizeException e) {
System.out.println("The number you entered must be positive. Please try again.");
}

I trying to write a piece of code which takes a set of numbers or even data type and stores in an array (or something more suitable).
For example:
Date N1 N2 N3 N4 N5 Day
10/11/2012 10 09 32 100 15 Thursday
11/12/2013 01 0 0 23 50 51 Tuesday
I'd like to be able to sort them so that if I want to search for one of the entries, I can then create a function which allows me to sort them by date or even return all the numbers by a given date or day, etc....
However, I'd like to be able to set it up so that each set is "linked" meaning that again that I can search by date and it returns everything at that date.
I wanted to use an array but I don't know:
-How to do it?
-Whether this is a suitable approach?

public static void main(String[] args) {
long start = 5000000;
long end = 10000000;

This particular program is supposed to prompt the user to input either an uppercase or lowercase Y to process a phone number, they are then prompted to enter the character representation of a phone number (like CALL HOME would be 225-5466), this repeats until the user enters something other than the letter Y. All of the words entered are to be stored into a single array. The program is then to convert these words in the array to actual phone numbers.
import java.util.*;
public class Program1 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String begin;
int phoneNumber = number.convertNum();
System.out.println("Please enter an uppercase or lowercase Y when you are ready to enter a telephone number: ");
[code]....
I realize that the second method doesn't have anything to return yet, I just wanted to put that in there while I was doing things that I actually know how to do ha. The convertNum() method is supposed to be the method with which the array of characters is converted to phone numbers.
would think it'd be easier to store the inputs from the user as individual letters rather than words for the sake of converting to phone numbers.
Also, we are only supposed to recognize the first 7 letters of each word that is entered, like the CALL HOME example, there are 8 letters but it's still a seven digit phone number, so I'm not sure how that would work.Also, when printing the phone numbers after they've been converted, we're supposed to print the hyphen after the third number, I have no clue how that would be done from an array.

I am having trouble with getting a user input once they enter it in to a JTextArea and then storing it in to a string value. See, I wanted the user to enter an answer in to the JTextArea, and then once I store it in to a string value, I would be able to use it later. I wanted to after storing the variable to print it on to a JLabel, but nothing is showing up... Heres my code.
static String usera[]= new String [10];
for (int i=0; i< usera.length; i++) {
//These are the JTextArea names
usera[0]= Question1.getText();
usera[1]= Question2.getText();
[Code].....
I already initialized the JLabels earlier in my code, and I did not feel the need to post all my code here. This is where I am trying to get the string variable and then printing it out.

I need to generate a league table in Java based on results provided in the shape of user input. I have the 6 teams in an array. I need to ask the user how many wins, draws, losses each team has had.
for (String element : teams) {
System.out.println(
"Please enter the number of wins, draws and losses for " + element);
int[] wins = new int [6];
int[] draws = new int [6];
int[] losses = new int [6];
}
How do I pull 3 separate values from the user and then store each value in a separate element of each array? so if one team wins 3, draws 2 and loses 1 - I need to put 3 into the wins array, 2 into the draws array and 1 into the losses array? I then need to total all this in a table.

The purpose of this program is to translate a user inputed sentence into morseCode. It seems like everything is right to me, but I'm simply not getting output! What am I doing wrong, or what should I add/change?
Here is the main class:

I created my own class and it basically randomizes the amount of 'spells' [magic] a user uses (range 1-5). I can't figure out how to increment the initial randomized output to make something like this :
User X : uses 2 spell.
User Y : uses 3 spells.
User X : uses 3 spells. (Taking the randomized 2 and increment by 1)
User Y : uses 4 spells. (Taking the randomized 3 and increment by 1)
My current setup looks like this : First one is the class I created and the second one is just how the output would look like. (seperate by +++++...)
My goal is to create a METHOD to increment it.
public class Spell {
// Max number of spells
private final int MAX_FACE_VALUE = 5;
// Current face value
private int faceValue;
// New instance of Spell
public Spell() {
faceValue = 1;
[Code] ....
+++++++++++++++++++++++++++++++++
public class SpellOutput {
public static void main(String[] args) {
//Object creation
Spell spellCasterOne = new Spell();
Spell spellCasterTwo = new Spell();
Spell spellCasterThree = new Spell();

The assignment: Ask the user to enter 2 ints. Output "true" if one of them is in the range 10 - 20 inclusive, but not both. Otherwise output "false"
12 99 → true
21 20 → true
8 99 → false
15 17 → false
