So I want the method getDisplayText of d to be returned as long as the for loop runs. When I do this I get a compile time error to enter a return statement. I am currently trying to fix it by returning an empty string, yet this doesn't seem the right way to go.
public static String displayMultiple(Displayable d, int count)
{
for(int i = 1; i <= count; i++)
return d.getDisplayText();
return "";
}
I'm working on a project that involves the following:
-Creating a superclass of bankaccounts
-Creating two subclasses, checkingaccount and savingaccount
-Each of the two subclasses has different methods (writeCheck for checking, for example)
-Both types are created in a main class bank and stored in the same array
So let's say a user goes through the menus and creates a few savingAccounts and a few checkingAccounts (stored in the accounts[] array). Then, to write a check from one account, the user can enter the account number (a string), and the method will use a for loop to cycle through the array until it hits an account number match. Then it checks that it's the correct account type and calls methods from the subclass.
Problem here is that some methods work and some don't. In the following example:
for (BankAccount account: accounts) {
if (account.getAccountType().equals("Checking")) {
do {
if (account.getAccountNumber().equals(accountNumber)) {
amount = Double.parseDouble(JOptionPane.showInputDialog(
[Code] .....
The getAccountNumber method works but writeCheck is throwing an error. I tried creating a method in the superclass and overriding it in the subclasses but with no success.
1. Modify the following class so that the two instance variables are private, there is a constructor that accepts both the player's name and sport and there are get and a set methods for each instance variable:
public class Player {
String name;
String sport;
}
2. You can pass an instance of this class to the JLabel constructor if you want to display text in the label.Select one:
a. myLabel
b. myText
c. String
d. JTextField
e. JLabelText
how to start making this work?cause i am not familiar with the terms here and want to complete this program and I am new to java programming?
In the code below, under calculations, I have x=totalPrice+xXxXxX. Obviously the x's were just place holders, but I wanted to know if there was any way to add something there so the program would tally the totalPrice, store it in the x variable outside the loop, so when the loop ended it would display the total price from all the loops added together where I have System.out.println("TOTAL OF ALL ORDERS: $"+ round.format(x)); at the very end.
Java Code:

public static void main(String [] args)
{
//Rounding
DecimalFormat round = new DecimalFormat("0.00");

I'm working on a simple text editor, and I'm currently saving the contents of my JTextPane in a file using an HTMLEditorKit (text is a JTextPane):
private void save() throws IOException {
int returnVal = fc.showSaveDialog(window);
if (returnVal == JFileChooser.APPROVE_OPTION) {
StyledDocument doc = (StyledDocument)text.getDocument();
HTMLEditorKit kit = new HTMLEditorKit();
BufferedOutputStream out;
[Code] ....
The problem I'm having is that after opening a file that I saved, it does not display (if I disable text/html, it displays the entire html code, but when I re-enable it, nothing displays at all.) Am I loading it wrong, or am I setting the JTextPane's text incorrectly? Or is it, perhaps, another error that I didn't catch?
We were given a class lab that asks us to write a program that create a multidimensional array ( 5 x 5 ), populates the array using nested loops with letter from A until Y, and displays the array to the screen. and the result should look like this:
A B C D E
F G H I J
K L M N O
P Q R S T
U V W X Y
How to write this program.. I have tried all my best but the results are not coming like this..

I am working with a program I wrote for class. I got it to compile and do what I want, But I was wondering how I can format my methods to to display a decimal with 1-2 decimal places. Would I create a method in my NumberAnalysis class to do it for me? Or would I declare an instance of the DecimalFormat class in my main method?
import java.util.Scanner; //Needed for Scanner Class
import java.io.*; //Need for File and IOException
import java.text.DecimalFormat;
public class Ex8_11 {
public static void main(String[] args) throws IOException{
{
DecimalFormat decformatter = new DecimalFormat("#0.00");
[Code] .....
This is my output:
Lowest Number: 1.09
Highest Number: 82.76
Total Number: 367.89000000000004
Total Average Number: 30.657500000000002
Think I just solved the answer to my own question, I did it by declaring double variables in my main method and called the methods and instantiated the variables into the methods... Is there a better way to do this?

My question is: The methods start()will give the indexes into the text where the found match starts .d*, this means if a number found.index must be returned. Why doesn't it print 3? 12345
Another question: Why it prints 6?

5>f
What is this 6 in out put?

I am in the middle of creating a chess application, and am currently working on laying out a list of moves on the right of the actual board. Specifically, I want to have a JLabel that says "moves" on top of a JList that contains the moves, on top of two buttons, labeled "<" and ">" respectively, to which I will eventually add functionality to take back and un-take back moves. Currently I have the first two parts down, but when I add my buttons,the other components are getting messed up.
I have all of these things in a vertical BoxLayout inside of a JPanel with a fixed width of 70, and a height that varies according to the size of the window (I overrode the getPreferredSize method of the JPanel). The two buttons are within their own JPanel with a grid layout with one row and two columns. Then I basically just add the moves list label, the movesList, and the panel housing the buttons to the larger panel, in that order.
However, I am encountering two problems. One, the buttons display the text "... " instead of "<" and ">" as if there is not enough room, although I'm pretty sure three periods take up more space than one less than or more than sign. The next is that, without the buttons at the bottom, the label reading "moves" is appropriately centered (or left aligned, I can't tell which) over the movesList, and you can read its whole text. However, when I add in the buttons at the bottom, the label of the top shifts over to the right and then reads "mov..." because it has run out of room.
Here is my code:
//move list
movesListLabel = new JLabel("Moves");
//the components for the actual movesList come from another class with an object called pen, but I don't think this is the problem
listModel = pen.getListModel();
JList movesList = pen.getMovesList();
JScrollPane listScroller = pen.getMovesListScrollPane();

like this 8 levels were there, finally at each level the Calling number should display in JTable.
I have to write a gui program where I can enter a file name and then it gets displayed in a text area when I click Open. Conceptually, I do not get this. I was thinking of appending the text file into a string or something, but I guess I'm confused on how it all works and how I can open the text file. Not asking for the code, but just a compass or something.
View Replies View RelatedSo currently I am trying to use a JTextarea to display text and I then prompt users to type in certain words. I have a few problems that I have encountered. Firstly when I use setText and then if I say setText again after that it erases the previous text that was set. Ideally I want to set text once per line in my whenever a certain task is fulfilled. For example if the text says enter y/n, I want the program to go to the next line once I say y or n. Another problem of course is when I setEditable to true I can edit the whole textArea. I just want to be able to edit the line which I am currently at. Is there anything that I can use that mimics the ACM console program, or even the console down below in most IDE's where everything appears to be done line by line?
Also here is an example of what I am trying to do, along with comments:
Java Code:
console.setText("Math is good!");
console.setText("What is 2+2?: "); //using getText gets the whole line, I want
//everything checked after the colon. That is where the input will be
if(line==4){
console.setText("That is correct");
}
else {
console.setText("That is incorrect");
}
//previous text lines are overriden with new ones. I don't want that, nor do I want to be able to edit the
//whole JtextArea mh_sh_highlight_all('java');
A JtextArea is just not getting the job done.
My instructions are to:
1. Prompt the user to input two positive integers: firstNum and secondNum (firstNum must be smaller than secondNum).
2. Output all the even numbers between firstNum and secondNum inclusive.
3. Output the sum of all the even numbers between firstNum and secondNum inclusive.
4. Output all the odd numbers between firstNum and secondNum inclusive.
5. Output the sum of all the odd numbers between firstNum and secondNum inclusive.
*Use while loop
int firstNum, secondNum;
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter an integer: ");
firstNum = keyboard.nextInt();

What to do with the while loop and how to find even and odd numbers.
