I need to display my calculations in a table format using loops.
//Imports
import java.util.*;
import java.text.*;
public class YourLoanCalculator {
[code]....
The increments are correct, but I wanted them listed under the "Payment #:" column. I figure that if I do that, I can also correctly display the interest, principal, unpaid balance and total interest paid at that point, right?
my java applet - displaying output with text
View Replies View RelatedI cant apply my knowledge of the switch to modify this program.
What i need is that the program runs the same but i can press q to stop the program and it will continue in a loop otherwise. repeating the same process i.e displaying the characters entered until q is pressed.
How do i do it? I think i need to make use of do and while but how to apply those in this case.
Here is my code so far. I am trying to get the WHILE LOOP to work so the user inputs a number, the if statement prints the output and then it returns to ask for another number and goes again and again looping :
import java.util.Scanner;
public class ifwhileloop {
static Scanner sc = new Scanner(System.in);
public static void main(String[] args) {
double nmbr;

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;
[code]....
my output fails to display me the 2nd output.Here's my code.
import java.util.Scanner;
public class year
{
public static void main (String [] args)
{
Scanner console = new Scanner (System.in);
System.out.print("Enter the choice of book(A-ABC,D-EFG):");
String x = console.next();
System.out.print("Enter the rate (1-3):");
int y= console.nextInt();
System.out.print("Enter number of kids reading:");
int k = console.nextInt();
[code]....
When I key '0" for kids, it did not appear the second print out. I don't want the first print out to be the output.

I have a problem with one method for my assignment. This is the requirement for this method: "This method uses a loop to list all accounts contained in the Array, adding each account details to a String, before outputting to screen in the format specified in the screenshot below. Ensure that there are no out of bounds exceptions by checking if each array slot has an account object before adding its details to the output String. (arrayname[index] != null)"This is my code for this method:
public void listAllAccounts() {
String allAccountsString = "List of all accounts:
";
for(int i = 0; i < ACCOUNT_SPACES; i++) {
//allAccountsString += accountArray[numAccounts];
if (accountArray[i] !=null) {
allAccountsString += accountArray[i].toString() + "
" ;
}
}
JOptionPane.showMessageDialog(null, allAccountsString);
The problem is that the Message Dialog does not display the accounts I have already created. It just displays "List of all accounts:
";

I created a instance of a class AddItemView, inside StartUpMenuController. I then passed it into the class, the main method is below showing that as well. However when I do this:
else if(e.getSource()==menu.addBtn)
{
new addItem();
}
I get an error, little red line on the bottom of the text. I am testing the frame at the moment to make sure it is what I want before I move on to the Controller side of it. I just want to display it and go from there.
package mainMenu.Home.DataBase;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import addItemBtn.Home.DataBase.AddItemView;
public class StartUpMenuController
{
StartUpMenu menu;
AddItemView addItem;

Not sure if this is the issue but the class I am making a new instance of is in a different package. I imported the package though.

One of my official site is not disaplying the content in machine#1 IE10 browser.And the same site is showing data in another machine#2. I compared the both machines JRE and JDK settings but no difference found.
how to link the JRE to browser.
why my image may not be showing. Note I am using eclipse.

I have used file.exists() and this returns true, and file.length() which returns the correct file size.
System.out.println(backgroundImage) returns "splash.png" so thats ok.
Why then is my image not showing?
so far this is what i have written. The program works correctly but I need to be able to have the numbers i am entering to show up on the .txt file.

I'm learning about inheritance and part of my problem is to create an Order with methods, then an UpdateOrder where the total price is changed by adding four dollars to it, and then a main method displaying a few orders. I've copied all three below in order. My question is when I run the program it will display the totalprice() first for the second order followed by name, number, etc.what you override always displayed first regardless of the order you put them in? (The issue is at line 31 on the third code.)
import javax.swing.JOptionPane;
public class Order { //superclass
private String customerName;
private int customerNumber;
protected int quantityOrdered;
protected double unitPrice;
protected double totalPrice;

1. Why, when I press "New" rapidly, will it skip painting shapes sometimes/adding to totcount.
2. How can I make it so that The box in the background(which is currently connected in the wrong way as I was getting an error when I connected it correctly) can be modifiably large. AKA, I want to draw a grid in the background that can be different sizes, depending on the values of a variable xsize and ysize.
3. What can I do to clean this up? All I want it to do is display the convex hull of the four points given in the int[][] displaypoints.
Yes my JPanel is not displaying all the time like you would think it would. Before you beat me up yes I am a bit new I am just working on the GUI part of java over my summer break. Obviously it is not suppose to do that. Secondly, As you can see i am using the alphabet to create JButtons. Shouldnt there be an easier way to use a for( loop) . I tried before but I didn't want to get too side tracked.

I have a JScrollPane and JTable inside. In the right column of the table at the end (south) I made a ChartPanel in one of the classes where I make the design for the Frame:
Java Code:
ChartPanel chartpanel = new ChartPanel(pieChart);
pCapturing.add(chartpanel, BorderLayout.NORTH); mh_sh_highlight_all('java');
And when I click on any row above, from the list in the column, I would like an appropriate pie chart to be drawn.
I need here (in another class where I define the getTableCellRendererComponent) to enter a code to display the chart in the last row of the panel:
Java Code:
PieChart3 pie=sectionsChartProvider.getSectionPieChart(section);
...
...
if((hasFocus) || (isSelected)) {
if(column == 0)
setBorder( new MatteBorder(1, 1, 1, 0, colorBorder) );
[Code] .....
But, I don't know how to do this. I also have a class for drawing the pie chart.
So I have this
function checkvalue (val) {
if(val==='replaced')
document.getElementById('check1h').style.display='block';
else if (val==='checked')
document.getElementById('check1h').style.display='none';
else
document.getElementById('check1h').style.display='none';
}
Which works fine... But if I try and add another document under the if VAL === replaced then nothing works and neither of the boxes appear.
function checkvalue (val) {
if(val==='replaced')
document.getElementById('check1h').style.display='block';
document.getElementById('check1n').style.display='block';
else if (val==='checked')
document.getElementById('check1h').style.display='none';
else
document.getElementById('check1h').style.display='none';
}
Is this not possible?
Also, Both of my input type are set up like this...
<input type='text' style='display:none' name='check1n' id='check1n' placeholder='Name of Part' />
<br>
<input type='text' style='display:none' name ='check1h' id='check1h' placeholder='Part Number' />
i have got an array which has come from a text file.
Parts of the array have been placed into a string.
So string one will have about 50 different values which I am able to print into the console using System.out.println("FirstString"); This prints all of the variables from the array so I end up with 50 words.
I am now trying to get this into a HTML document.
I have correctly done this and I get some out put when the webpage opens.
My problem is that I only have 1 work which is displayed.
