I am doing a simple program, just to find multiples of 7 all the way to 125. But the loop its not stopping at 125 and is going to 126.
public class Assingment2B {
public static void main(String[] args) {
int number = 0;
while (number <= 125) {
number += 7;
if (number % 7 == 0) {
System.out.println(number);

I am doing an assignment which involves creating a maze and a ball that needs to go through the maze to an end tile then stop the scenario. The maze is made up of 208 buttons in a Jbutton Grid layout. I am replacing certain buttons with a brown tile icon to make up the maze. The ball needs to run along those brown tiles as its path and not be able to move off the brown tile icon images.
I have built the maze and have got quite far with this but now I am stumped on the concept of keeping the ball within the boundary edges and on the brown tiles. I have been told to use if statements, but not had the process explained to me in a way I can understand.
I am currently in the process of making a game in java. it's going fairly well, however, one problem that i am having is that i cant seem to get my enemy sprites not stack up onto one another. What i want to happen is if two enemy sprites come in contact with one another i want them to touch but not to overlap. However, i cant seem to get this to work.
This is the enemy class:
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Rectangle;
import java.util.ArrayList;
import javax.swing.ImageIcon;
public class Enemy extends Base {
int x;
int y;

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 "

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 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");

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.

Can i write inner if loop without { and } if it has more lines of code as below

I just started to teach myself loops. I am trying to convert the while loop into for loops, however somehow I do not get the same printout.
While loop:
import java.util.Scanner;
public class Test {
public static void main(String[] args) {
int i = 1;
int sum = 0;
[Code] ....
Print:
sum is 0 and i is 1
sum is 1 and i is 2
sum is 3 and i is 3
sum is 6 and i is 4
Create a loop where you add the integers from 1 to 50.
public class Sum50 {
public static void main(String[] args) {
int sum = 0;
int max = 50;
for(int i = 0;i <= max; i++){
sum=sum+i;
}
System.out.println("Sum is " + sum);
}
}
I'm fairly new to programming, just started yesterday with a book I downloaded of the net. The book comes with a couple of examples on how to code and they all seem to work fine except for this loop.
class fordemo {
public static void main(String args[] ) {
int count;
for(count = 0; count < 5; count = count+1);
System.out.println(" This is count: " + count);
System.out.println("Your are all done! ");
}
}
I can't seem to find the problem. All it gives me is,
"This is count: 5
You are all done!"
When it's supposed to give me,
"This is count: 1
This is count: 2
This is count: 3
This is count: 4
You are all done!"
Found the error, semicolon after the for loop is not necessary. Should be...
class fordemo {
public static void main(String args[] ) {
int count;
for(count = 0; count < 5; count = count+1)
System.out.println(" This is count: " + count);
System.out.println("Your are all done! ");
}

I wrote a program using switchcase.I used do while to show the menu to the user until the user decides to exit the menu.I used try catch to prevent ant exception and it worked properly.But i got one problem.When exception occurs,desired msg is printed but i am unable to display the menu to the user.So user wont be able to continue after an exception is caused.

It makes no difference in the program wither i delete this block or keep it..how while (choice < '1'| choice >'2'); translates? I would assume it would be while (choice >= '1'| choice =<'2');?
