So I have a text file, and I want my Java program to store names from the text file. How do I do that? This is what I have so far.
Java Code: import java.util.Scanner; import java.io.File; BingoCard[] cards = new BingoCard[n]; //Array of BingoCard objects, n being the length of the Array Scanner sc = new Scanner(File("Names")); //Names is the name of the file for(int c = 0; c < cards.length; c++) cards[c] = new BingoCard(sc.nextLine); mh_sh_highlight_all('java');
Here's the constructor.
Java Code: private string myName; public BingoCard(String name) { myName = name; } mh_sh_highlight_all('java'); Whenever I compile, I get this error message.
How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap? Currently my program reads the data from several text files in a directory and the saves that information in a text file called output.txt. I would like to cache this data in order to use it later. How can I do this using the TreeMap Class? These are the keys,values: TreeMap The data I'd like to Cache is (date from the file, time of the file, current time).
import java.io.*; public class CacheData { public static void main(String[] args) throws IOException { String target_dir = "C:Files"; String output = "C:Filesoutput.txt"; File dir = new File(target_dir); File[] files = dir.listFiles();
Within tomcat "webapps" directory, have lots of scanned PDF files (size in KB and MB).Using Java and JSP, I want to search for any user entered text in these scanned PDF files.The result must display the name of those PDF files which has that entered text.
I have a problem in reading the text file. I have my source text file at "D:/input.txt".When the below code is executed the following errors are coming.
" java.lang.NoClassDefFoundError: Try Caused by: java.lang.ClassNotFoundException: Try at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method)
I am stuck with my application. I have jsp, servlet application with jasper report server. When I run the application through eclipse, everything works perfectly. But When I try to run it in Tomcat (without eclipse) it gives me the "Unable to resolve the class file " error. I tried all the solutions I got through the google, but still I am unable to come over it.
In my java app there is a code which reads the properties file from src/main/resources folder.
Java Code:
@Component("mailerProperties") public class MailerProperties { private static Properties properties; public MailerProperties() { properties = new Properties();
[Code] ....
Now I need to create a jar file and also remove the properties file from src/main/resources folder and place it outside the jar file(in the same location as jar file) so that data inside it can be changed easily in future.
Question: Currently it uses ClassPathResource("mailer.properties") to read the prop file. What change I need to make to read it from outside the jar file...
I'm trying to read images and draw them on JLabel. This code snippet below is reading images from a folder
private ArrayList<ShowItem> getData() { int score = 0; ArrayList<ShowItem> item = new ArrayList<ShowItem>(); File dir = new File(getImageFolderPath()); if (dir.isDirectory()) { for (final File f : dir.listFiles(IMAGE_FILTER)) { BufferedImage img = null; try {
[Code]...
ShowItem is a class that extends Image. DisplayImage extends ShowItem.
One of the overridden methods in ShowItem is
@Override public Graphics getGraphics() { return null; }
I'm not exactly sure what to do here so I left it.
In another class, where I draw the images on Jlabel. This is what I have:
I tried to run it, and check if I'm actually getting the images, and did system out and it listed all the jpg images I have but it's not displaying on the panel.
This is what i have so far, I use BlueJay to write this:
import javax.swing.JOptionPane; public class payroll { String again = y; // private String name; private double rate; private double hours; static double gross; //gross pay
[code]....
my first problem is that it expects a ")" on this line :"if ((hours <=40)rate *1);"For the assignment itself these are the requirements:
-Create a class called payroll with private variables for rate hours and name
-Create static variables for gross pay, union dues, health coverage (hp in my case), FICA taxes, State taxes, Federal taxes, net pay, all must be initialized to 0
-default constructor that assigns default values
a function called calcPay that will do the following tasks and print it to a pay stub :
- function that checks the hours ( if hours are 40 or less pay rate, if over 40 pay 150% of the rate) - calculates gross pay before any deductions (using user inputted hours and rate) - deduct medical coverage and union dues from gross pay and call this adjusted gross pay (also this should have its own line on the paystub) - A function that deducts State, federal and fica taxes from adjusted gross - FICA - 7% for any income -Federal - 2% for $0-$150 / 6% for 150.01 - 300 / 14% for 300.01 - 600 / 18% for 600.01 - unlimited -State - 1% for 0-150/ 3% 150.01 - 300 / 5% 300.01 - 600/ 8% 600.01 - unlimited - amount after all deductions is the net pay ( show this amount on its own line) - Start a loop that asks each time if there are more employees (y/n) y should continue the program and n should end it -dialog boxes should be created to recieve values for name, hours and rate - if the rate is entered below $8 dollars a new box should pop up and ask for a higher value - When there are no more employees, print out a summary of quantities stored in static variable (also had a problem with this) - End
So I think i completed most of these objectives but am having trouble with the syntax and some of the objectives
So my only error in the entire code is on the 9th line of this code sample. It says "Syntax Error on token "new", @ expected" but @ does not belong there, as far as I can tell, since the error does not go away upon adding it.
public class Obstapacalypse implements KeyListener, ActionListener { private static final String EXIT_ON_CLOSE = null; private JFrame frame; private Player player = new Player(); private JPanel contentPane; private JButton btnStart;
i have to save some particular info of a pdf file info into a database.there are lots of folders with tons of pdf files to be analized and then getting that info saved. make the process incremental? i need the program to stop at some point. and then continue to analize the resting files in the folders (i dont want the program to start all over again from 0 )my ideas are..sorting all the files using apache commons sort (by date) method (iv seen it somewhere) and saving the last file analized in the dabatase to then continue. OR just adding some extra character to the pdf file name that has been analized like for example xx-xxx.pdf to xx-xxxa.pdf.
My issue is that when I run the code if I enter anything but 1, 2, or 3 the code breaks. I have spent hours trying to find the error. here is my code
import java.util.Scanner; public class Tester { public static void main(String[] args) { /** * constructor * pre: none * post: inherit values of other classes */ Car Car = new Car(); //inherits the properties of the Car class Truck Truck = new Truck(); //inherits the properties of the Truck class
I'm not sure why I'm getting these errors. They only begin to happen after the second if statement, and the subsequent if statements are formatted exactly the same.
The errors are marked by the comments in the code.
Java Code:
import java.util.*; import java.io.*; public class GazillionSongs { public static void main(String[] args) throws FileNotFoundException { System.out.println("Welcome to Java Song Collection!"); System.out .println("This program sorts and filters large databases of popular songs.");
My if else statement is not working...it keeps telling me that the else in the statement is a syntax error and that I should remove it. Whats wrong with it?
package Homework2; import java.util.Scanner; public class Homework2 { public static void main(String[] args) { // TODO Auto-generated method stub System.out.println("Welcome to the Triangle Program.");
I am currently using the following Rally API Java code(below...in Java 1.7) to create an object and attach a file to it. This code works fine. But I need the code to be a little less specific and attach all files located under a folder (not just one file). How could one potentially rewrite this code (or use a different constructor/method) to accommodate such a thing? Also additional code how to narrow down results to all files with a creation date >= today.
I have a problem with my code. It gives me the error I put as title:
backgroundA.setOnClickListener(new View.OnClickListener(){ public void onClick(View view){ if (j < 2){ int randomInt1 = random1.nextInt(Deck.length()); int drawableIDA = Deck.getResourceId(randomInt1, -1);
[Code] ....
This error is in the first line and I have also one in the last, where eclipse looking for a @ (O.o). Also I will insert the variable choice1.
final Button choice1 = (Button) findViewById(R.id.A);
I am currently working on modules of a java program but am having issues with this module . it gives this error code"syntax error on token '?', invalid primitive type".
