That's correct......The file is there with nothing in side......

Yes sorry it does repeat for other files, Problem is that it doesn't print to the file at all

public class Writer { public static void writeFile(String File) { //Write back to file for system time try { //if file exists, data will be overwritten File file = new File("data", "systemTimes.txt"); //Print data to file try (PrintStream out = new PrintStream(new FileOutputStream(file))) { //Print data to file out.println(Calendar.getInstance().getTime()); } out.close(); } catch (IOException ex) { } //Write back to file for interest Rates try { //if file exists, data will be overwritten File file = new File("data", "interestRates.txt"); PrintStream out = new PrintStream(new FileOutputStream(file)); //iterate through arraylist for(int i=0; i<Bank.interestRates.length; i++) { //Print each object's data to file out.print(Bank.interestRates[i] + "\t"); } out.close(); } catch (IOException ex) { ex.printStackTrace(); }

I'm trying to figure out why this will not actually print to the file
Any help would be appreciated

Guess overthinking the problem was my biggest problem. I just figured it was something more complex.

Thanks for the information.

No I have no restrictions on this exercise. I wrote the program last week and got 18 out of 25, miss putting a priority to the right level and this part.
I originally printed out "AA thru BB" 6 times instead of what I need now.

for(int i=1; i <=6; i++){ System.out.println(i + " thru " + i); }

Which produces:
1 thru 1
2 thru 2
3 thru 3
4 thru 4
5 thru 5
6 thru 6

I've search the wrong books or what to search on the net to figure away or how to the following output:
1 thru 10
11 thru 20
21 thru 30
31 thru 40
41 thru 50
51 thru 60

Can some one give a clue or a place to look, driving me nuts

I have the following code but need to read from a file

public static void main(String[] args) { // TODO code application logic here double length = 0.0, width = 0.0; // instantiate a standard input object Scanner readuserinput = new Scanner(System.in); // prompt user for rectangle's height and width System.out.print( "Enter rectangle length and width (e.g: 10 10): "); // read and store rectangle's height and width length = readuserinput.nextDouble(); width = readuserinput.nextDouble(); // instantiate and initialize the myrectangle object // of type rectangle class Rectangle myrectangle = new Rectangle(length, width); // do some formatting for the double DecimalFormat fmt = new DecimalFormat("0.##"); // print rectangle's length, width, area, perimeter and diagonal // to standard output System.out.println("The rectangle length is: " + (fmt.format(length))); System.out.println("The rectangle width is: " + (fmt.format(width))); System.out.println("The rectangle area is: " + fmt.format(myrectangle.getArea(length,width))); System.out.println("The rectangle perimeter is: " + fmt.format(myrectangle.getPerimeter(length,width))); System.out.println("The rectangle diagonal is: " + fmt.format(myrectangle.getDiagonal(length,width))); } }

import java.util.ArrayList; import java.util.Collections; import java.util.Scanner; public class lotto { public static void main(String[] args){ Scanner input = new Scanner(System.in); { ArrayList<Integer> numbers = new ArrayList<>(); System.out.println("How many tickets would you like?"); int ticketNumbers = 0; while (true){ //loop for user entering number of tickets ticketNumbers = input.nextInt(); if (ticketNumbers <= 100 && ticketNumbers >= 0){ break; } } for(int i = 0; i <= 49; i++){ //loop for range of numbers numbers.add(i); } for (int i=0; i<ticketNumbers; i++) { //loop for printing # of lottery tickets Collections.shuffle(numbers); //randomly shuffle elements of arraylist System.out.print("\nTicket "+(i+1)+ ": "); for (int j=0; j<6; j++) { // determine how many numbers for each ticket System.out.print(numbers.get(j) + " "); } } } } }

output is:
How many tickets would you like?
5

Ticket 1: 1 30 38 39 45 14
Ticket 2: 35 3 42 18 40 2
Ticket 3: 27 7 19 40 25 35
Ticket 4: 34 17 0 4 38 33
Ticket 5: 14 6 5 46 48 1

The following is my requirements:
•Each row is called a "play." The plays are lettered A, B, C, etc.
•There are always an even number of plays on a ticket. (Lotto tickets cost $1 for two plays)
•Each play has the following characteristics
•There are 6 randomly selected integers
•The integers are from 1 through 44
•Integers may not be repeated
•Integers are sorted from smallest to largest on each line
•Integers are always shown as 2 digits. If the number is less than 10, a leading zero is printed.
•There are a maximum of 10 plays per ticket. (A - J)

Your program should begin by asking the user to enter an even number of plays. The program should do "input validation" and not let the program continue until the user enters an even number. The minimum requirement for this program only requires you to pick numbers up to 10.

Here is my code below

My problem is that the current print out to my file is:
*

continue with the current program, but try to print all of the above in a single println,
which would mean using a StringBuffer, or StringBuilder to create a single String of the above
so it would be
String message = [will end up as all of the above];
System.out.println(message);

now when it prints out exactly as above, you change
System.out.println(message);
to
javax.swing.JOptionPane.showMessageDialog(null,message);

Ok, I've re wrote my code, but instead of printint in a dialog box like:

What does that mean? It seems contradictory to me.

If you are reading from a file, you ought not to do it in the main method. Your main method contains 49 lines. That is 48 too many. You ought to have a method which reads from the file. Then you can create an object of a class which encapsulates the pay, tax allowance, parking tickets, etc. You are inappropriately using the static keyword for things which ought not to be static in your example.

You see the program I was given was:
Re-write programming assignment # 3 with the following exceptions:
1. Your program must read input from a file.
Input file definitions:
First Name, Last Name, Hours Worked, Pay Rate, Parking Tickets
Example:
Linda Lou 45 10.50 3
Sam Martin 40 15.00 1
2. Modularize your program by sending parameters too and receiving data from at least the following 4 methods that must be invoked:
a. Calculate your gross pay.
b. Calculate overtime if it exists.
c. Calculate your net pay.
d. Pay Parking tickets if needed.
3. Write results to an output file in the following pay stub format for each employee :

Sam Martin
Basic Pay $600.00
Overtime Pay 0
Gross Pay $600.00
State Tax Amt $54.00
Fed. Tax Amt. $120.00
Total Taxes $174.00
Net Pay $426.00
1 Parking ticket $20
Total Pay $406.00

I need to read from a file that is set up like called (filename.txt)
Linda Lou 45 10.50 3
Sam Martin 40 15.00 1
Mike darvin 56 12.75 2
jeff corbin 42 13.65 4
Joseph smith 37 15.25 5
peter thomas 52 11.35 0

but I have to do it from a pane because I cannot figure out how do it easier without having to type it in from a window.

But right now my Output file is:

null null
Basic Pay $0.0
Overtime Pay $0.0
Gross Pay $0.0
State Tax Amt $0.0
Fed Tax Amt $0.0
Total Taxes $0.0
Net Pay $0.0
Parking Ticket $0.0 Total Pay $0.0

which should output all the files

I need Someone to help me or show me what I need to do for the average to print out correctly

Overall Class Average is 21.67 ****HERE'S THE PROBLEM*****


The following lists the number of students earning each letter grade:

Number of A's = 4
Number of B's = 4
Number of C's = 3
Number of D's = 2
Number of F's = 2


The following program generates 3 random numbers, then averages them.

The average of 22 43 49 is 38
