Display Phrase In Every Font Size From 6 Through 20
Jun 1, 2014
I'm trying to display a phrase in every font size from 6 thru 20. As it stands now, the code below cascades the phrase, sort of, down the frame, but the font size doesn't change.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class JFontSizes extends JFrame implements ActionListener
{
JButton button = new JButton("Press Me");
String aPhrase = new String("This is a phrase.");
[Code] ......

The result looks something like this:
Button
This is a phrase.
This is a phrase.
This is a phrase.
This is a phrase.
etc.

So, I have a game. I would like to make a game where you press "start" and THEN it starts. Also, I want to have collision with triangles, not just squares. The way I handle collision right now is with if statements, if the object is within the other, game over.How would I do collision with triangles? Lastly, how do I set a high score? how to change fonts and font size in swing?

I want to hyphenate a token which is present in a database. My code:
String str = "The Appointments Committee Cabinet has approved the appointment of Dr. Harry Potter, Chief Economic Adviser, Department of Economic Affairs as Executive Director in the International Monetary Fund.";
String[] words = str.split(" ");
LinkedList<String> linkedlist=new LinkedList<String>();
for (int i = 0; i <= words.length-1; i++) {
linkedlist.add(words[i]);
[Code] ....
I want to implement this algorithm, I will start with "The Appointments", whether it is present in table or not. If yes, then move forward and check for the next token- whether entry for "The Appointments Committee" is present. If yes, then again move forward, and check for "The Appointments Committee Cabinet". If entry is present, then again move forward, if not, then move back, then hyphenate "The-Appointments-Committee". Then again start with "Cabinet"- the same process all over again. I want to use a select query- it should give a smaller result set, so the speed should be much faster.

I am quite familiar with using JOptionPane and its various displayXDialog() methods and reasonably familiar with changing fonts.
I have a JOptionPane.displayMessageDialog() that is working fine but I decided to make the font larger.
I found an example from which I coded:
Font font = UIManager.getFont("OptionPane.font");
UIManager.put("OptionPane.font", new Font(font.getName(), font.getStyle(), 24));
font = UIManager.getFont("OptionPane.font");
JOptionPane.showMessageDialog(this, "Welcome to Mover", "About Mover", -1); // no icon
After the UIManager.getFont() call after the UIManager.put() call, font shows the new font size of 24, but the showMessageDialog() dialog still has the default font.
And yes I understand that, when this works, it will affect every JOptionPane in my program.
I also tried:
Font font = UIManager.getFont("OptionPane.font");
JOptionPane message = new JOptionPane("Welcome to Mover", JOptionPane.INFORMATION_MESSAGE);
JDialog dlg = message.createDialog("About Mover");
[Code] ....
This gave me a dialog with the default font and an unwanted icon.
So I tried
// both
Font font = UIManager.getFont("Dialog.font");
// and
Font font = UIManager.getFont("JDialog.font");
and planned to use that font in my setFont() call but font was null.

I was wondering, if, for example I set font for my textarea like this:
area.setFont(new Font("Serif", Font.ITALIC, 18));
Is that last parameter, in this case 18, will be actually the same size for all users? Maybe I should avoid these absolute numbers?

It's very simple, I've added an AWT component/control (specifically a Choice object to a Frame. It's a pop-up menu by any other name.
Above the pop-up, there's a label. I'm trying to change its font to no success.
* I create Label object called label1: Label label1 = new Label("This is a pop-up")
* I create a Font object called f: Font f = new Font("Times New Roman, Font.BOLD, 18)
* I apply the new font to the label: (in AFrame's constructor) label1,setFont(f)
When displayed the label's font seems to be stuck on Arialor something similar. Changing the point size however does have an effect.
import java.awt.Choice;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
/**
* Defines a 'pop-up' AWT control that will be added to AFrame.
* It extends Choice - I may need extra functionality later.
*/
public class APopUp extends Choice implements ItemListener {
// instance variables
int noi; // no of items
String selected; // item selected from choice
[Code] ....

I am having some troubles with a program fileviewer where you must be able to change font style and size when pressing JButton "Set font". I have solved the most of the program and every menu button is working but I don't know how to set in FileListener class method to change the font when running in main class. Anyway, this is my FileListener class
Java Code:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.io.*;
import java.util.*;
import java.awt.Font;
public class FileListener implements ActionListener
[code]....

The Font style constants are of int: int[] fontStyleList = new int[] {Font.PLAIN, Font.BOLD, Font.ITALIC};But what do I do when I want to add the names such as PLAIN etc. as the name of a menu item?
The following is not going to work, right!String[] parts = (fontStyleList[i].toString()).split("."); or String[] parts = ("" + fontStyleList[i]).split(".");rbStyle = new JRadioButtonMenuItem(parts[1]);
Is there another way to do this or should I just do another array with the names as a String?

I wish to print the content of a JTextArea. I know I can do this with textarea.print(). However, I wish to print in a different font, font size and orientation from that of the JTextArea itself. I have been able to change the orientation by setting print attributes
PrintRequestAttributeSet printAttributes =
new javax.print.attribute.HashPrintRequestAttributeSet ();
printAttributes.add(javax.print.attribute.standard .OrientationRequested.LANDSCAPE);
And then using the textarea.print() method that allows me to set attributes. However, I haven't found any way to set the font and font size.

I'm working on Java-GUI implementation in Ubuntu. Used font-type in the application throughout is "Arial". At earlier stage of application it was the same font-type("Arial"). As the implementation grew the font-type has been changed automatically to another font type. It seems Serif-font type.
Now I could not able to figure out the problem; why it is so.
Note- I used HTML code also for setting font style of Dialog box messages and buttons. This is the only point which I figured out. Can it is ?

Write a class named FileDisplay with the following methods:
1.) constructor: the class's constructor should take the name of a fil as an arugment.
2.) displayHead: This method should display only the first five lines of the file's contents
Here is the following code I have made so far
import java.io.*;
public class FileDisplay
{
private String filename;
public FileDisplay(String Filename) throws IOException
[Code] ....
First, in my constructor I have taken in an argument and used that argument to open up an output file. Meanwhile, I'm trying to work n the displayhead method to print out information and to read data to. I haven't opened up my input file yet, but I'm not understand how can I read a print data to an output file. in
public void displayHead()
{FileWriter file=new FileWriter(Filename)}
do I make create another instance of the filewriter class to output data?
In simple words, suppose to I want to display some messages on my output file in the displayhead function. Since I already have opened up the file in the constructor, how do I combine that in this method...

I am developing a product where the client needs to display the content of XML in a JSP page. This XML will be extracted from database and will be temporarily sotred in a String object and will then be flushed to JSP page for display. This was working fine unitl now. But now the customer wants display each tag with one color. attribute in another color and data in another color.
For ex: <?xml version="1.0" encoding="UTF-8"?>
this should be displayed in one color. Then
<ichicsrmessageheader>Data</ichicsrmessageheader>
In the above one the tag should be displayed in one color and "Data" should be displayed in another color
<organisation operationtype="1">Data</organisation>
In the above sample tag should be in one color and attribute should be in one color ex: red and value of the attribute should be in another color ex: blue and "Data" should be in one color ex: green.
Here is the sample screen shot of how xml should is currently being displayed.

I am asked in my assignment to make a program that accepts a text file as an example a novel and i have to sort each word as a PERSON or ORGANIZATION or LOCATION or O as in Other , example :
Microsoft/ORGANIZATION ,/O Nelly/PERSON !/O '/O
Now we notice that microsoft is and organitzation and "," is Other and Nelly is a person's name and so on ..
Now I am asked to return the numbers of tags in the text which is 4 in our case because we have (ORGANIZATION,PERSON,LOCATION,OTHER)
My question here is my logic true ? And since i made a map of String,String ; Is there any way that i can get the size of the values in our case the values are the organization etc.. ?

I am just not sure of some theory in collections, ArrayList and LinkedList maximum capacity depends on the memory allocated to the JVM. But according to few people those list has a maximum capacity of Integer.MAX_VALUE.
According to my experiment, those list has a maximum capacity of Integer.MAX_VALUE since the get method of List accept a parameter of int primitive type (index of element), therefore we can conclude that the maximum capacity of List is equal to Integer.MAX_VALUE.
But what about the Map? get() method of map accepts object(the key of the map). So does it mean that the maximum capacity of Map depends on the memory allocated to our JVM? Or its maximum size is Integer.MAX_VALUE also just like Lists and Arrays? Is there a way to prove it? Is Map designed to hold infinite number of data (disregarding the heap memory space exception)?
And also about Stack, Deque? is it also the same as Map (in terms of maximum capacity)?

I have the textfile which has lines:
A B 2 midterm 100
C D 1 final 90
C D 1 midterm 90
A B 2 final 80
**NO ARRAYLIST IS ALLOWED!** And the textfile is passed into the method. How to get the size for the array non-randomly inside the method from the passed Scanner file?? What if you have lots of numbers of lines, so how could that be done?
I have doubts about this line Exam[] object = new Exam[12];
Java Code:
public static Exam[] readAllExams(Scanner s) throws ArrayIndexOutOfBoundsException
{
String firstName = "";
String lastName = "";
[Code].....
