In the class below I'm trying to create a class that will accept dates in various formats and create a range. The first constructor is easy because I send it the begin date and end date as Date objects. Now I want to send a month(and year) in a constructor and derive the begin and end dates from it. In my constructor that accepts the month/year I need to put the this(startDate, endDate) at the top to be allowed, but the parameters are not built yet.

I'm new to Java and I have an assignment to create a Sphere class that will allow you to create Sphere objects using the code below. Then create a program called SphereTester that prompts the user for the radii of two spheres in meters. The program should display which sphere is larger and by how many cubic meters and display only four digits after the decimal point. I have the sphere class given to us for the assignment which is this:
Java Code: public class Sphere {
// instance variable (i.e., a field)
private double radius;
// constructor for the Sphere class
public Sphere(double r) {
radius = r;

p.setTitle("How I spend my day");
p.setSlice1("Sleep: 7 hours", 7, Color.black);

I want a menu with buttons that looks like this:
Button 1: Start

If you press one of the buttons you will get to another frame with new buttons, new labels and so on.
Next step for instance if you press button 1, I'd like my program to get this frame:

public Die(){

I would like to create a custom tag which works similar to <c:forEach/> tag i.e
<c:forEach var = "movie" items = "${collection}>
${movie}
</c:forEach>
I would want to create the similar behaviour(as above) in my own custom Tag.Morever I would like to use the doStartTag() and doEndTag() and doAfterBody() methods while creating custom Tag.
create a jar file.Currently I have next files in my directory:
Manifest.txt:
-------------
Manifest-Version: 1.0
Created-By: 1.7.0_60-ea (Oracle Corporation)
Main-Class: connectURL
connectURL.class
------------------
it compiled fine, can be executed as:
java connectURL
it does not have 'Package' specified
sqljdbc4.jar
-----------
This is jdbc 4 jar file which is used by connectURL.java to make db. connection.
I am running:
C:j>jar cvfm connectURL.jar Manifest.txt *.class sqljdbc4.jar
added manifest
adding: connectURL.class(in = 2427) (out= 1358)(deflated 44%)
adding: sqljdbc4.jar(in = 584207) (out= 549364)(deflated 5%)
Then trying to execute and get error message
C:j>java -jar connectURL E520 1433
Error: Unable to access jarfile connectURL
how to create a JAR File I have been watching you tube and it seems like the manifest needs to be remade. I go to the CMD and find my project folder class. I think I need to use do the same for all the classes correct. Well I type jar -cf TictacToeGUIGame.jar *java then I get no such directory. I can see the it worked thought. So do i do this to all my classes and then I will have my JAR program?

I am making a Sudoku game and creating a matrix of JTextFields. However I am getting the following errors
Exception in thread "main" java.lang.NullPointerException
at SudokuView.board(SudokuView.java:30)
at SudokuView.<init>(SudokuView.java:18)
at SudokuMain.main(SudokuMain.java:5)
I know the problem is with this code
box[i][j] = new JTextField();
panel.add(box[i][j]);
I know this because when I do this:
panel.add(new JTextField());
It works. However it puzzles me why it is not working.
Whole Code:
import java.awt.GridLayout;
import javax.swing.*;
public class SudokuView {
JFrame frame;
JPanel panelBoard;
JTextField[][] box;
int row=10; int col=10;
SudokuView(){
frame = new JFrame("Play Sudoku GOOD LUCK");

I'm making a small play in java in which you have a limited time to make as many moves as possible (with the aim of achieving a maximum score), like this: URL...
In the game panel I see the map on which you will perform the moves and a score indicator constantly updated. I have to add the indicator that shows me the passage of time (first 3 minutes), in digital format mm: ss. I thought I will be a useful thread called Countdown because I have to stop this counter if the user presses the pause button in the game. Then wanting to continue the game shall resume the countdown.
I keep getting this as a result:
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous tree type: myprojects.Balloon
