Getting Right Answer In While-loop
Jan 29, 2015
If I for example choose 8 as "multiplikationstabell" and 4 as "faktor" the whole code works except that "svar" gets printed as 8 in every turn. Why? "Faktor" gets added with 1 every time but "svar" stays at 8.......
import java.util.Scanner;
public class Multiplikationstabell {
public static void main(String args[]){
Scanner Heltal = new Scanner(System.in);

I have tried as much as I can to place code to give me only two decimals in answers but cannot get it to work not sure if placement or syntax.This is code so far and it works but gives answers to 8 decimals.

I am new to programing and I am making a dice game where I have to roll two dice and add the total together for each dice (2, 3, 4 ect.) I have all the program finished except one thing.
How would I use the * character that shows the total percentage each number was rolled. Each * will represent 1% of the total rolls. Instead of saying there were ( 4 ) 2's rolled i have to put ( **** ) 2's rolled.
2: ***
3: ******
4: *********

Will the postfix x++ and the prefix --y change the answer for this question?
If x has the value 10 and so does y, then what is the value of (x ++) * (-- y)?

I want to design an open-answer quiz game using Java. Basically, the plan is to design a quiz where the name of a medicine is displayed as "the question" and the player will need to input the unique code (as "the answer") of the medicine in an open box (all the codes are two characters). The list has about 204 named medicine (with potentially more to be included at a later stage). The questions will not appear in the same order for each session restarted; they will appear randomly.
The player will have 60 seconds, and for each correct answer, will score 1 point and add 2 seconds to the timer. The player will also have 6 "lives", and for each incorrect answer, the player will lose a life, with no effect on the time.
The idea of the game is that the player memorise as many of these medicine codes as possible.

I am writing a simple learning program that does basic math. Everything is working as needed except for when it comes to division. I need to know if there is a way to format the users input to two decimal places and that when the program checks the users answer against the division, it gives it a yay or nay. Right now, it wants the answer out to 12 decimal places.
So for 5/3
I would like it to accept the answer 1.67
not 1.666666666667
Is there a way to do this?

I am having trouble figuring out where to put %.2f in my code. I need it to get my answers for surfaceArea and Volume to be rounded to two decimal points. I have everything completed but wherever i put it, it seems to not work.
System.out.println("This program will compute the volume and surface area of a rectangular prism.");
String output;
double length;
double width;
double height;
double volume = 0;
double surfaceArea = 0;
System.out.printf("%.2f", surfaceArea);

I want make a math equation game. usually math game use equation for the question and we answer that equation. ex : what is the result of 2*5 / 2+2/ 2^2 etc. and we answering that. but i want to make it different so i want to make the equation answer as the question and the equation as the answer of the game. Ex : the question is 54 so we can answer it with 9*6 or 24+30. and this is my java code
package coba;
import java.util.Scanner;
public class Coba {
public static void main(String[] args) {
double angka = Math.random()*70;
[Code] ....
but when i run it the error code show like this : Quote

I mean its not that important but i figure it will be better if I could print out the answer both in fraction format and decimal format. while my answer prints in fraction just fine how do i show it in decimal?
System.out.println("");
System.out.print("And ");
System.out.print("answer in Decimal is: ");
decimalAnswer = ((double)numeratorAnswer/denominatorAnswer);
System.out.println((float)decimalAnswer);

Code in the book is written exactly like this:
import java.util.Scanner;
public class AdditionQuiz {
public static void main (String[] args){
//Generate random two integers using utility System.currentTimeMillis
int n1 = (int)(System.currentTimeMillis() % 10);
int n2 = (int)(System.currentTimeMillis() / 7 % 10);
[Code] ....
however the true/false result can not be printed due to the "answer" variable...

Is there any kind of way to generate HTTP request within a servlet, dispatch it to the server and get back the answer delivered to the servlet? Or are the servlets meant only to respond to passed requests, not generate them?

The problem occurs after the user inputs the guess.... it either runs the for loop if guess = numtoguess and reveals the answer even if the user input is wrong.... or it always runs the first if statement in the while loop if guess!= to numtoguess... heres the code
public static void main(String[] args) {
String[] Answers = {"yes", "Yes", "No", "no"};
String Name = JOptionPane.showInputDialog(null, "Hello, What is your name?","Random Game", JOptionPane.QUESTION_MESSAGE);
String UI = JOptionPane.showInputDialog(null, Name + " do you want to play a game", "Random Game", JOptionPane.QUESTION_MESSAGE);

I am trying to print a loop inside an array of a greater size than the loop itself. Like for example I have an array of size 7 but it has only 3 elements.
int[] array=new int[7]
array[0]=2;
array[1]=3;
array[2]=4;
now what I want to do is print these three numbers in a loop so that my array[3]=2;array[4]=3;array[5]=4 ...... till the last one. Also the array could be any size and not just 7.

Here's the code: it's while loop inside a for loop to determine the proper length of a variable:
for (int i = 0; i < num; i++) {
horse[i]=new thoroughbred();
boolean propernamelength = false;
while (propernamelength==false){
String name = entry.getUserInput("Enter the name of horse "
[code]....
I was just wondering what was going on here -- I've initialized the variable, so why do I get this message? (actually the carat was under the variable name inside the parentheses.

I have everything else working. My problem is that when i type "quit" to close the outer loop. It still runs the inner loop. The National Bank manager wants you to code a program that reads each clients charges to their Credit Card account and outputs the average charge per client and the overall average for the total number of clients in the Bank.
Hint: The OUTER LOOP in your program should allow the user the name of the client and end the program when the name entered is QUIT.In addition to the outer loop, you need AN INNER LOOP that will allow the user to input the clients charge to his/her account by entering one charge at a time and end inputting the charges whenever she/he enters -1 for a value. This INNER LOOP will performed the Add for all the charges entered for a client and count the number of charges entered.
After INNER LOOP ends, the program calculates an average for this student. The average is calculated by dividing the Total into the number of charges entered. The program prints the average charge for that client, adds the Total to a GrandTotal, assigns zero to the Total and counter variables before it loops back to get the grade for another client.Use DecimalFormat or NumberFormat to format the numeric output to dollar amounts.
The output of the program should something like this:
John Smith average $850.00
Maria Gonzalez average $90.67
Terry Lucas average $959.00
Mickey Mouse course average $6,050.89
National Bank client average $1,987.67
Code:
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String name = "";
int charge = 0;
int count = -1;
int total = 1;
int grandtotal = 0;
int average = 0;

I'm using eclipse. I'm going to get straight to the point and give all the info I can, if the values in the first code box are used, shouldn't these values be left after all in the second box is done:
remainder=23, arr[0]=100, div=23/10=2.3, whole=2, and decimal=3?
When I use this code, div comes out to be just (2.0).
Java Code:
int leng=10;
arr[0]=123; //int
arr[1]=100; //int mh_sh_highlight_all('java'); Java Code: if (arr[0]!=arr[1]){
int remainder=arr[0]-arr[1];
arr[0]=arr[0]-remainder;
double div=remainder/leng; //double div=Double.valueOf(remainder/leng);
int whole=(int) Math.floor(div);
int decimal=(int) ((div-whole)*leng); mh_sh_highlight_all('java');
I'm not sure were I'm going wrong in how div is being calculated, but I ultimately need div to be 2.3.
I've also used the second option commented out which still gives (2.0).

I am trying to make a program add values from a loop. So what its supposed to do is search through tokens on an imported file. The file lists State, Capital, and then capital population. Then take the population string, turn it into numbers, and then do stuff with the numbers. First I'm supposed to find the Highest and lowest population of the places in the file (which I did without problem), but the finally thing is I'm supposed to add each found population to the last so I can find the average of the populations.
I just cannot seem to grasp how to do that. I THINK I'm supposed to some how store the given value into a variable, but how do I get that variable to add to the new value?
like...?
Get token -> a
b = a
c = a + b
or wait no.....
Java Code :
import java.io.*;
import java.util.Scanner;
public class CapPopS
{
public static void main(String[] args) throws IOException
{
File stateCAP = new File("state-capital-2004population.txt");
if (!stateCAP.exists())

My teacher wants me to make a program that counts the amount of steps a student takes a day. The program asks for other info such as name, age, college. However I need to write a loop that will allow the user to enter how many ever steps they took and convert them to miles.how exactly to make the steps entered by the user within the loop be their own individual days like monday tuesday etc. Like the loop will ask how many steps did you take monday.. tuesday.. etc for each time it runs.

This is the first time I've ever gotten an infinite loop with a FOR loop. This program is supposed to let you enter five integer numbers and draw a bar chart based on those numbers. After the fifth number is entered, guess what? It wraps back around to zero again and starts over! Why the bleep doesn't it stop? The code is below:
