I am trying to make a program that get input value 1-200 from user. However I would like to make the program to show warning if the input number is not within the range of 1-200. In the end I would like to show the amount of number according to its interval (i.e less 50, 51-100 and so on) ....
import java.util.Scanner;
class test {
public static void main (String[] args) {
int number[]= new int[5];
int number2[]= new int[5];
int a=0,b=0,c=0,d=0,i=0;

I've four classes object. I don't know how to display the amount paid by the user, and show the balance. The calculate button just show the total amount. Do I have to create another object class? And I've to show the bills too.
This is my 1st Frame

Web based program, basically a slide show template where the user uploads a series of photos, they are dumped into the pre-fabbed template of a predetermined set of transitions in sync with music. I will set the templates to transition based on the time stamp of the beat of the music at certain intervals. The end users will be able to then create their own slide show "movie" based on the templates.
Problems I see are the syncing between the music and the images loading. Wondering if it's doable client side or if I need to have it rendered server-side.

[ATTACH=CONFIG]27j.jpg49[/ATTACH]Hello,
I'm having the hardest time getting a program to compile. I'm beginning to think I've downloaded the incorrect version of turtle graphics. This symbol looks foreign and I'm unsure how to find a solution. I have fixed some of the errors since this last picture but I will write out my code. The program takes a photo and converts to gray scale then to sepia
import images.APImages;
import images.Pixel;
import java.util.Scanner;
public class sepia{
public static void main(String [] args){

We have been given an assignment to create a small library, with the following classes Library, Book, Author and Copy. With a given class Biblio which has predefined code and adds the books to the class book in an arraylist in Class Copy.
The UML Domain is attached so you know the flow of the classes Everything is working fine and the generated output is correct.
There is just one method in class Library that is not working, the int method has to count the number of Copy's based on the Class Book (String):
I have to go through the Arraylist in Class Copy and look for a specific book and return the number of copy's.
I have tried multiple steps using a for loop Now I have found a similar post the uses hashset, I have tried below code but the return comes back with 0. (There are 3 copy's)
package domein;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;
import domein.Boek;
import domein.Exemplaar;
[code]....

I have a calculation that sorts books by rating...
System.out.println("
" + "
Sorted by Rating
");
for (int count = 0; count < bookL.size(); count++) {
for (int in = 0; in < bookList.size() - 1; in++)
if (videoList.get(in).getRating() < bookList.get(in + 1).getRating()) {
[Code] ....
What am I missing here? Why doesn't this work?

I was trying to come up with the design for a library. Here are the requirements:
The library maintains a record of books and its members. It allows members to check out books. Books can be searched by author name or title. The books are classified into 4 categories - General, Sports, Politics, Business.
I've come up with this initial design:
Classes:
Category (enum)BookMemberLibrary
Category
Attributes: SPORTS, GENERAL, POLITICS, BUSINESS
Book
Attributes: String title, String authorName, Category category, boolean checkedOut

I have the following code.
class A {
List<StringBuilder> list;
public void output(List<StringBuilder> objectToOutput){
try(BufferedWriter bw = new BufferedWriter(new FileWriter("temp.txt"))){
for(StringBuilder row:objectToOutput) bw.write(row.toString());
}catch(IOException e){}
[code]....
Why don't the a's show up on the console? I put them in as part of the debugging process and now I don't understand why they don't show up in both places.

my "test" class:
import javax.swing.JFrame;

public class FaceTest
{
public static void main(String[] args)
{
String head = JOptionPane.showInputDialog("Would you like a circle, square, rectangle shaped head?: ");

public static void main(String[] args) {
boolean t=false;
long cuTime = System.currentTimeMillis()
while(t==false) {
System.out.println(cuTime);
long g=cuTime+2000;
[Code] ....
I tried this and it includes a while loop as the whole program has to wait until this while loop executes. So the entire program slows down. Is there any way to do this without a while loop

I am trying to make a program to multiplies two numbers without using the "*" operator. My idea was to add x number y amount of times, which is the same as multiplication. I did this with a for loop, but zero is always returned as the answer. How can I fix this?
public class secondMult {
public static void main(String[] args){
System.out.println(multWithSum(4,5));
}
public static int multWithSum(int x, int y){
int sum = 0;
for(int i = 0; i==y;i++){
sum = sum + x;
}
return sum;
}
}

This is the code ive written:

Here is what I'm trying to do using arrays.
gather sales amount for the week
display the total of sales
display the average of sale
display the highest sale amount
display the lowest sale amount
using occurrences determine how many times the amount occurred for the week
make a sales main
make a sales data
This is what i have so far but I'm confused on how to start the occurrence and where it would be placed in order to get the information from the array
public class SalesData {
private double[] sales; // The sales data
/**
The constructor copies the elements in an array to the sales array.
@param s The array to copy.

I have a question about how to delete only a certain amount of objects on screen in a graphics window. I have a method that will enable me to get rid of every object of the same type off screen, for example this method:
Java Code:
public void deleteTrees() {
//clears all tree trunks and leaves
for (Iterator<GRect> it = historyT.iterator(); it.hasNext();) {
GObject gobj = it.next();
this.remove(gobj);
[Code] ....
That Will delete all trees.
Now In my main method I populate the screen with trees by doing this
Java Code:
for (int xpos = 10; xpos < getWidth() - 40; xpos += getWidth() / 8) {
drawTree(150, 200, xpos, getHeight() / 2.0 - 50);
historyT.add(trunk);
historyL.add(leave);
} mh_sh_highlight_all('java');
My question is how to specify only deleting x amount of trees instead of the whole thing. I pretty sure I need to use something like history.remove(trunk) and to iterate through the amount of trees specified, but not sure how to implement that.

I'm doing this project in JSP.net, with html. and in one of the web pages, what I'm doing is that, a person is transferring an amount to someone else, and if the transfer amount is more than the account balance, then he cannot transfer. else, save details in a table.
Here's the code I've used
<%
String t1=request.getParameter("text1");
String t2=request.getParameter("text2");
java.util.Date date1 = new java.util.Date();
SimpleDateFormat ft = new SimpleDateFormat ("dd/MM/yyyy");
int tamt = Integer.parseInt(t2);
int bamt = 0;
[Code] .....
But when i enter the fields and click the submit button in the form, to save it in the table, i get the error:
"org.apache.jasper.JasperException: java.lang.NumberFormatException: null"
(I've attached a screen shot of the error) : NumberFormatException.bmp (750.98K)
What does this mean? how do i find the line in the code that has the error?
