How To Automatically Increment ID And Then Display Only One ID In Report
Jun 7, 2014
The program shall assign a new employee ID to the employee and display it on the screen.
The employee ID shall be generated by adding 1 to the largest employee ID already in the employee.txt data file.
You can see I've tried variations of identification++ but have not been successful. I've also tried to get the last or the highest identification in the arrayList but have not done that right.
public static void addEmployee() {
String firstName = Validator.getString(
sc, "Enter First Name: ");
String lastName = Validator.getString(
sc, "Enter Last Name: ");
int identification = 0;
[Code] ....
I also can display all of the employees their identifications and their punches but I cannot narrow it down to searching one employee and displaying information for just the one.
-If the selected value is ‘I’, prompt the user to enter the employee’s ID number.
-If ‘I’ is selected the display shall show the employee’s name and ID, list out each day worked in chronological order, the number of hours worked that day and a total number of hours worked in the two week period.
The report shall prompt the user to re-enter an employee ID of it does not exist in the employee file.
private static void displayReports() {
System.out.println("Report");
Scanner sc = new Scanner(System.in);
String action = " ";
while (!action.equalsIgnoreCase("d"))
I'm trying to display an columns and rows. The first column has integers and the rest are doubles. The initial calculations are correct, but I cannot figure out how to total last column, which is interest paid, and then start the iteration over.
int paymentNumber; //print out the colum labels System.out.printf("%7s %9s %10s %8s %15s %n", "Payment", "Interest" , "Principal", "Balance", "Interest Paid"); System.out.print(" "); //put three blank spaces first //Test For Loop Output: for ( paymentNumber = 1; paymentNumber <= period*12; paymentNumber++) {
[Code] .....
Here's the output: It displays the payment number correctly. Am I supposed to write a for loop for each column?
run: Please enter the amount of the loan: 1000 Please enter the interest rate: 1 Please enter the loan period in years. 1 Your Monthly Payment is:$83.79
I created a jsf page inside my ADF project. Inside I have a button and a text field. If i press button my servlet is activated. It returns a jasper report in pdf format. Now I would like to display my text field value as a jasper report parameter. So this is a part I don't know how to do. How do I get a value of my text field inside servlet? After this I know how to pass it to report.
These Stand alone XML's getting compiled and will generate report.
However i want to create these using Jasper Report API. I have Just started. But stuck without any example available.
JRDesignSubreport jSubreport = new JRDesignSubreport(jasperDesign); jSubreport.setUsingCache(false); jSubreport.setRemoveLineWhenBlank(true); JRDesignExpression subReportDataSourceExpr = new JRDesignExpression(); subReportDataSourceExpr.addResourceChunk(""); //How to set List Data Source?
I'm writing a JavaFX desktop app, and would like to make it automatically run after installation, but I'm not sure where to look to make this happen (or even if it's possible?). I have successfully created a .dmg installer using E(fx)clipse & Ant. Are there options I'm overlooking which I can use in the build.xml? or am I looking in the wrong place entirely?
I have developed an application using Java JSP and PostgreSQL database which inputs data from users including multiple file uploads in different formats (MS Word, Excel, PDF etc.). The uploaded files are also stored in the database.
My client wants the software to print a report in PDF format which includes all user data entered (in a defined format) along with all the uploaded documents as appendices.
How the system can include all uploaded files into one PDF report?
How to print database report in hard copy. I have try to do this with the code below but it only print empty plain paper. Find the code below:
printbtn.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e){ Vector columnNames = new Vector(); Vector data = new Vector(); String host = "jdbc:odbc:staffsalary";

I have a question related to the code below, that I do not understand. The aim is to count all files and subdirectories in an ArrayList full of files and subdirectories. So I have to count every file and every subdirectory.
The code concerning counting files is clear to me - every time d is of the type file I have to increment n by one. However I thought that I have to do the same thing in case d is a directory, so I would have written the same code for directories.
So what does "n += ((Directory) d).countAllFiles();" mean? In my understanding the method countAllFiles() is applied again on the object Directory ( as Directory is the class that contains this method), but how is n incremented by this? I thought n should be incremented by one as we did with files.
public int countAllFiles() { int n = 0; for(SystemFile d : content) { if(d instanceof File) { n++;
private String eventName; private ClockDisplay timeOfEvent; public static final int MIDNIGHT_HOUR = 00; public static final int MINUTE_ZERO = 00; }
How can I create a method called public void addMinuteToTimeOfEvent() which calls the timeOfEvent's increment() method to add one minute to the timeOfEvent?
I have a code issue and I have a below question for the same.Assuming data[] is of type byte[], is the below statement in java -
while((data[p++] & 0x80) == 0x80);
same as -
while ( (data[p] & 0x80) == 0x80 ) { p++; }
I tried with do { p++; } while ( (data[p] & 0x80) == 0x80 ); That also doesn't seem to be the same thing. I am not putting code around this but essentially if I make this change for not using data[p++] code stops working!

I need open a url every time I want to refresh system with an update. Each update has a number so my urls are url1, url2, url3, ... I know how to put it in a loop to increment the urls in a String. I do not know how to make it open and close the url in a browser.
public class Test { public static void main( String args[]) { for (int i = 201; i < 300; i++){ System.out.println("http://url=" + i);
The array size is fixed improve it to automatically increase the array size by creating a new larger array and copying the contents of the current array into it .I am using a course class and here is the code for the class
public class Course { private String courseName; private int numberOfStudents; private String[] students = new String[100]; public Course(String courseName)
[Code] ....
As you can see I have the array set to size 100, how do i make so it increments each time the user adds a student.
I am trying to get random shapes to generate automatically. I was able to get just three shapes to generate but nothing random. When I added the random code now only the frame shows up and no shapes. I also keep getting an error with frame.setVisible(true). It says identifier expected. Here is what I have so far:
Main program:
import javax.swing.*; import java.awt.*; import java.util.Random; public class ShapeGen { public static void main(String [] args) { //Create window and set title draw panel = new Draw();
[Code] ....
This is the draw program to generate random shapes:
import javax.swing.*; import java.awt.*; import java.util.Random; public class draw extends JPanel { public draw(Color backColor) { setBackground(backColor);
I'm working on an assignment that says the following.
" The array size is fixed in Listing 10.6. Improve it to automatically increase the array size by creating a new larger array and copying the contents of the current array to it.Implement the dropStudent method.Add a new method named clear() that removes all students from the course.
Write a test program that creates a course, adds three students, removes one, and displays the students in the course."
10.6 Listing
public class Course { private String courseName; private String[] students = new String[100]; private int numberOfStudents; } public Course(String courseName) { this.courseName= courseName;

The problem I'm having is, for the first part of the question where I need to automatically increase the array size. I'm really not great at this stuff. I have tried breaking it down, but can't "get it", I guess.
I assume, it'd be a loop that checks to see if the student array is full and if so, do the increaseArray() part, by maybe multiplying the student array and then assigning it. I just don't know how to do it haha.
My *best* attempt at the loop so far has been
if (students == students.length){ int bigArray = 2*students.length; String increaseArray()= new String[students]; System.arraycopy(students, 0, increaseArray, 0, students.length); students= increaseArray;
I need a list of all the dates in 2014 in "YYYY-MM-DD" format (because I need to load them into a database), and I do not want to type them all myself. So is there a way to actually get it generated automatically?
I have this assignment to build an employee time clock. By using a menu you can enter an employee, enter punch in and out, and report.When I created the punch screen I wrote the in and out records to a file. Because there can be several employees punching in or out the file wrote each occurrence on different lines. Now I am attempting to write the report which you enter an employee Id and loop through the file to find the in and out date and then calculate the time (hours worked). I loaded the file into an Arraylist but now I cannot figure out how to loop through find the In and Out date - calculate the hours worked and then move on to the next day. here is the format of the file - employee id, place holder I or O, date, time, day. and sample
I am having trouble creating the for loop in the Parking Simulator. I dont even know where to start. I have searched google and I havent found any Parking simulators that used array lists. Here are the requirements:
The ParkingSimulator Class: This class should simulate checking the parking tickets. You should loop through the cars, choose a random officer, and have that officer check to see if there is a parking violation. If there is a violation, add it to the ParkingTicket ArrayList. After all have been checked, print out a summary of the tickets (using the toString() from the ParkingTicket class).
I think I have all the classes right except for the ParkingTicket Class which I know is screwed up in the for loop because I cannot get the random officer and create and report ticket if mins were over maxlimit and it is printing the whole string of officers when it should be picking one officer at random to assign to the ticket. Also it is not printing out the whole output.
output should look like:
VW with license # N34234 parked for 60 minutes at PM1 and a maximum time limit of 90 minutes - no violation. Reported by officer Joe badge: PO123
Mazda with license # 234-567 parked for 70 minutes at PM2 and a maximum time limit of 60 minutes was parked illegally for 10 minutes for a fine of 25.0. Reported by officer Sam badge: PO812
etc;
Summary of tickets: License:234-567 at meter #:PM2: Fine: $25.00 License:W879HY4 at meter #:PM4: Fine: $25.00 License:BG65RF7 at meter #:PM5: Fine: $25.00
I am developing an inhouse project in my organization. I unable to implement the pdf uploading, downloading, report generation logic as i am totally new to this implementation.
char array[] = new char[10]; int i = 0; array[i++] = (char)('A' + i); System.out.println("char for array is: " + array[0]); mh_sh_highlight_all('java');
However, the result for array[0] is B. Not A. from my understanding, the array[0] should be 'A'.
So I'm trying to make a bar graph, each bar will increment the height by about 10 pixels. To do this, I'm making an array of bars. For some reason, using fillrect I cannot not increase the size more than 10 by 10, if I do, it will only show the 10 by 10. I want the bars to increase in height by 10 each time.

Working on problem in my book in which I have to print a range of integers from x to y with an increment of 5. I thought I had the right idea when writing out this code, but apparently, it only gives a few of the numbers in the range, not all, what I am doing wrong?
import java.util.Scanner; public class Ranges { public static void main (String[] args) { Scanner input = new Scanner (System.in); System.out.print("Enter a value for x and y: "); int x = input.nextInt();
