We have a problem with a JavaFX application running on Java 7. Sometimes a form (BorderPane) does not show correctly – it seems to be transparent (i.e. content previously shown at the same place is still visible). Controls seem to be present and respond to events – e.g. we can close the form by blindly clicking the appropriate button. Once the issue happens it is persistent, i.e. next time we open the form, it behaves the same.
We have no reproducible scenario leading to the issue. It just happens here and there – we have not been able to identify any pattern yet.
Additional information:
The form (BorderPane) is loaded during application start-up but it is not shown initially,to show the form we remove previous contents from a StackPane and add the form instead,to hide the form we do the reverse.

I have written program for rainfall that will store and give total, average, least and most. The program stores the input of rainfall for each month. However at the end it suppose to print out the month with the least and most rainfall. I am getting this on the print for
The month with the most rainfall: [Ljava.lang.String;@79a7bd3b
and for
The month with the least rainfall: [D@7378aae2[Ljava.lang.String;@79a7bd3b
. What have i done wrong?

Write a program that stores the total rainfall for each of the 12 months into an array of doubles. The program should have methods that return the following:
The total rainfall for the year
The average monthly rainfall
The month with the most rain
The month with the least rain
And the code:
double rain[] = new double [12];
double sum;
double average;
double most;
double least;
[code]....
I'm having a problem with figuring out how to show which month is the least and most.

}catch(IOException e){}

Why don't the a's show up on the console? I put them in as part of the debugging process and now I don't understand why they don't show up in both places.

I am assigned with a project that will as the user for the amount of days they would like data entered, then loop asking them for these numbers. once it reaches the entered amount of days it will display a menu for which the user can enter the number they want on the list and it will display the data. the menu has 6 items. Total, Average, Determine if its a Drought, Flood or normal rainfall, highest of data entered, lowest of data entered, and 6 is to quit the program.
So far i have total and average working properly. Still looking at how to display drought, flood, and normal.
Main problems, i cannot get highest and lowest to display correct data.
Also when entering 6, or an invalid menu choice, neither "goodbye" or "invalid choice, choose again" gets printed. Rather the loop for entering data continues.
import java.util.Scanner;
public class RainAnalysis {
/*
* Project 1 This program will analyze the rainfall for the number of days a user inputs.
*/
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
int numOfDays = 0;
double rainfallAmount = 0.0;
[Code] ....
Here is a sample output to show what happens when i put in 6 after the menu is displayed.
also i noticed that it does not say the correct day when displaying the lowest and highest rainfall. this is because i put count, i did not know what else to put in order to get the correct day.
how many days do you want to monitor rainfall?5
Enter the rainfall for day 1.01
Enter the rainfall for day 2.1
Enter the rainfall for day 36
Enter the rainfall for day 43
Enter the rainfall for day 51
Rainfall Data Display Menu:
1 - Display total rainfall.
2 - Display rain average for the period.
3 - Display if drought, flood, or normal conditions.
4 - Display the day and amount of the highest rainfall.
5 - Display the day and amount of the lowest rainfall.
6 - Quit the program.
Enter your choice:
4
Day5 has the highest rainfall with 6.0 inches.
Rainfall Data Display Menu:
1 - Display total rainfall.
2 - Display rain average for the period.
3 - Display if drought, flood, or normal conditions.
4 - Display the day and amount of the highest rainfall.
5 - Display the day and amount of the lowest rainfall.
6 - Quit the program.
Enter your choice:
5
Day5 has the lowest rainfall with 0.1 inches.
Rainfall Data Display Menu:
1 - Display total rainfall.
2 - Display rain average for the period.
3 - Display if drought, flood, or normal conditions.
4 - Display the day and amount of the highest rainfall.
5 - Display the day and amount of the lowest rainfall.
6 - Quit the program.
Enter your choice:
6
Enter the rainfall for day 6

"Create a project called RainFall and a class nameD RainFall. Write a program that stores the total rainfall for each of 12 months into an array of doubles. The program should display total rainfall for the year, the average monthly rainfall, the month with the most rain and the month with the least rain. When outputting the month with the most and least rain, output the name of the month. This is what I have so far.

When input validation for the first months rainfall is non-negative, this results in correct average rainfall.
When input validation is used for the first months rainfall I'm prompted to input a positive number, which is 2.
When asked to input rainfall, in inches, for each month, I begin with input -3, I am again prompted to re-enter a positive, I enter 3. What happens is, whichever positive integer I input after I had entered a negative for the first months rainfall, the average would be off by the positive number inputted.
package averagerainfall;
import java.util.Scanner;
public class AverageRainfall
{
public static void main(String[] args)
{
int maxYears;
int totalMonths;

I am currently trying to make a method that will enable a jLabel to be dragged across the screen. I want to be able to drag the object pretty much anywhere on the screen(I hope to eventually make a destination for it where it can be dropped but I will get to that later). I have looked on various places on the internet on how to achieve this and the most simple solution does something like this:
Java Code:
jLabel6.setText("jLabel6");
jLabel6.addMouseMotionListener(new java.awt.event.MouseMotionAdapter() {
public void mouseDragged(java.awt.event.MouseEvent evt) {
jLabel6MouseMoved(evt);
}
});
private void jLabel6MouseDragged(java.awt.event.MouseEvent evt) {
x = evt.getX();
[Code]...
This actually works somewhat but it is very faulty. For example the jLabel keeps appearing and reappearing as I drag it. Furthermore when I drag it I can see a duplicate Jlabel being dragged as well in the top left hand screen. So how might I fix this?

I am trying to write a date program. I have it written and running correctly, except one issue. I cannot get the numerical date to display correctly. I know it is an issue with printf. I don't know anything about printf. Here is my method to return the day
public int getDay() {
return day;
}
When it returns, it is literally returning just the numeric date. I need it to show up as 02 or 03 instead of 2 or 3, respectively.

I will add my files and current output and desired out put below.
