Difference Between JavaFX And Swing?

Jan 28, 2014

I know that oracle has released a statement saying that JavaFX will eventually replace Swing. What is the advantage of JavaFX? The new format, using "stage" instead of JFrame, seemed weird. Why is this change necessary? What benefit do we reap from JavaFX that Swing does not have?

Swing/AWT/SWT :: Difference Between CreateImage And CreateVolatileImage

May 2, 2015

I'm calling createImage(x, y) to create a canvas to draw on. Works fine. Decided to add a UI to my little program. So I made a JFrame, put my JPanel with my image in it, and added the UI. Now createImage() returns null, digging shows isHeadless() is returning true.Make a new container (JFrame), put the working JPanel into it, and add the UI as well? Or should I be doing something else?

While I'm at it, what's the difference between createImage() and createVolatileImage()? Quality google time indicates the latter is a newer version of the former, but I found nothing to either confirm or deny that guess.

How about a little bit of code. RunGUI is the class that does display related stuff, it runs in it's own thread. 'game' is the JPanel that used to work on it's own.

JPanel game = null;
public RunGUI(String filename)
{
// For some reason my window isn't big enough. sigh
final int FUDGEX = 18;
final int FUDGEY = 40;

[code]....

Difference Between Eclipse And JDK?

Feb 27, 2014

I'm not sure if that's the right place to ask

But I am a bit confused:

I know that JDK means "Java Development Kit" , but isn't Eclipse the same thing? (so why it's called "IDE"?)

Or maybe Eclipse is a type of JDK?

Or actually JDK and Eclipse are 2 different things

How To Calculate Difference Between Two Dates

Oct 19, 2014

I have been tasked with creating an invoice (school assignment). Part of the calculations is creating an interest depending on the amount of days between the current date entered, and invoice date entered (The program prompts the user to enter both the current and invoice dates by asking for the day, month and year).

We are also supposed to set the contructor to a default date of 1/1/1900.. but I don't know how or where to code that.

How to calculate the difference between the CurrentDate and Invoice. I have displayed the dates to the user as follows.

public void displayDate() {
System.out.println("
Today's Date: " + month + "/" + day + "/" + year);
}
public void displayInvDate() {
System.out.println("
Invoice Date: " + invMonth + "/" + invDay + "/" + invYear);

Difference Between LinkedList And ArrayList

Feb 19, 2014

I have just begin to understand collections in Java. I read about the differences between LinkedList and ArrayList but have several doubts on it. I have mentioned them below

1) Why retrieving in ArrayList is faster then LinkedList?. Since both have the get method how does performance differ?.

2) How does re-sizing happens internally in ArrayList when a item is added or removed?. How slow this is compared to the pointer re-shuffling in LinkedList when a item is added or removed?.

Difference Between InputStream And InputStreamReader

Jul 11, 2014

I read that InputStream is used for byte based reading it reads 1 byte at a time.And InputStreamReader is used for charcter based reading so it reads one charcter at a time so no need to convert this first to int then read it.Here is reading using InputStream.

input=new FileInputStream("D:/input.txt");
int c;
while((c=input.read())!=-1)
{
System.out.print((char)c);
}

and here is reading using InputStreamReader

input=new FileInputStream("D:/input.txt");
reader=new InputStreamReader(input,"UTF-8");
int c;

while((c=reader.read())!=-1)
{
System.out.print((char)c);
}

so what is difference between InputStream and InputStreamReader in both case i have to use a Int and then read it and at the end if I want to print that data I have to cast that with "(char)c".So what is advantage of using InputStreamReader?

Difference Between Application And Applet?

Apr 13, 2014

Can explain difference between applet and application?

What are differences in code? How to write application?

What are differences in use? I looked for some answers, but I can't understand what they are talking about.

For example:

Application:

Called as stand-alone application as application can be executed from command prompt

Applet:

Requires some third party tool like a browser to execute

But... While I export applet in exclipse I can use it without any browser, just like application(as I and avarage user knows it).

Ok, I understand difference like "Applets cannot read from or write to hard disk files."

So. What should I use while creating what?

For example, something as simple as windows calc, some 2d simply platformer, some more expanded app, like idk, spotify or media player or whatever?

Since after update 51 of java web applets are nearly useless(as I know, maybe I'm wrong?), what is better?

Can application have GUI or it is only applets thing(stupid question?)?

Where can I find any application tutorial? Everything that I found was for applets. Why?

Difference In Days Between Dates

Dec 5, 2013

I know this has been covered before but none of the answers made sense to me. I'm hoping there is an easy way to do this. I have 2 user inputted strings that I have converted to dates and I just want the difference in days.

My code :

import java.util.Date;
import java.text.SimpleDateFormat;
import java.util.Scanner;
import java.text.ParseException;
public class DateTest {
/**
* @param args the command line arguments
*/
public static void main(String[] args) throws ParseException {

[Code] ....

Apparently I can't just subtract the dates like I would in VB.

Difference Between Keywords And Literals

Jul 5, 2013

Keywords are the predefined definition known to compiler like public/static/void/class

And literals are String/init/double/char/ , so here for e.g. String , its also predefined class ..

So will it be right to say that literals are also keywords?
