How To Take Input Text File With Terms And Create Glossary With Hyperlinks
Nov 28, 2014
I'm working on a project where I have to take an input text file with terms and create a glossary with hyperlinks. I've got it working halfway. It outputs the html files for some but not all of the terms and I can't figure out why.
I'm getting these errors:
Please enter the location of the input file: data/terms.txt
Please enter the location for the glossary: data/testOutput
Exception in thread "main" java.util.ConcurrentModificationException
at java.util.LinkedList$ListItr.checkForComodification(LinkedList.java:953)
[Code] .....
How would I fix them??
Code :
import java.util.Comparator;
import components.map.Map;
import components.map.Map2;
import components.queue.Queue;
import components.queue.Queue2;
import components.sequence.Sequence;
[Code] ....

So I was going to try to create a program that prompts input and creates a file (That didn't exist before) with that input as name.Then, the program prompts inputs after stating questions such as 1 + 1, then if the user inputs an answer, put "Question # = Correct "or" Wrong.Code SO Far:
Java Code:
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
public class File_Read {
public File_Read() {//File_Read is the Interactive object
[code]....
So that it puts the Correct or Wrong into the file.

I am working on a project that requires me to build a database with random access file, representing products, the base product contains a name (about 30 characters), a price (double), and a quantity (integer). I have worked on this project for probably 15+ hours and have tried so many things and feel like I've barley made any progress...
The part i am really struggling with is taking the data from the text file and creating an object array with it using the product class. Once ive accomplished that, i have to use that data to create a random access file with the data. Here is the base Product class that must be used to create the objects for the array.
public class Product
{
public String pName;
public String stringName;
public double price;
public int quanity;
[Code]...
these continue for about 40-50 entries, they are not seperated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name seperated with spaces, then price after a comma, then quanity after the second comma.....

I am new to java and I am creating a system that will ask the user to create a file that will store to a text file, Once the user created the file I have a class that will let the user input the subject name that has been created, However, I keep on getting this java.util.nosuchelementexception.Here's my code:
public void display_by_name()
{
String id, name,total;
String key[]=new String[30];
String value[]=new String[30];
int i=0;

Well my code is supposed to ask for an input file and then (ex: input.txt), read the input file and create an output.txt file with the anagram for the words in the file. Also it should be displayed on the screen. However my code doesn't display the anagram on screen or the output file!
Heres is the code:
import java.io.*;
import java.lang.*;
import java.util.*;
/* This program will read a file given by the user, read the words within the file and determine anagrams of the given words. If the file that the user inputs is empty, then the program will output "The input file is empty."
* The program will read the file line by line, counting the total number of words read. If there are more than 50 words, "There are more than 50 words."
* will be printed, and the program will terminate. After each line is read, the words in the line will be separated,punctuation characters will be removed, and upper case characters will be switched to lower case.
* If any word is larger than 12 characters, that word will not be considered in the total amount of words in the file and it will not be sorted.
* After each word is read, the letters will be sorted and stored into an array containing each
* word's 'signature'. After all the words have been read, words will be printed to the output file on the same line based upon their signature.
*/
public class Anagram {
//Creating constants for maximum words in file and maximum chars in word
public static final int MAX_CHARS = 12;
public static final int MAX_WORDS = 50;
[Code] ....

I'm attempting to compare user input to a text file that I have set up whenever the user types in an employee ID number. I want to be able to tell the user that either the ID number is valid, or that it is not valid and must be re-entered by comparing it to the employee.txt file, and then record the valid ID number to the timeclock.txt file. I'm recording the next available employee ID number instead of the one I typed in. The output of the program looks like this: i82014/06/06 12:16:56 (I typed 1 as the employee ID.)
import java.text.*;
import java.util.*;
import java.io.*;
import java.nio.file.*;
public class TimeClockApp {
// declare class variables
private static EmployeeDAO employeeDAO = null;
private static Scanner sc = null;

I need to write a program where the user inputs name, age, email, and cell and write the user inputs to a text file. I need to have it so the file can be added to if more than one set of information is added. Currently, every time I click the button, the file is overwritten instead of added to. How do I correct this? Current code is as follows:
try
{
FileWriter writer = new FileWriter("ContactInformation.txt");
BufferedWriter bw = new BufferedWriter(writer);
nameTextField.write(bw);
bw.newLine();
ageTextField.write(bw);
bw.newLine();
emailTextField.write(bw);
bw.newLine();
cellTextField.write(bw);
bw.newLine();
bw.close();
nameTextField.setText("");
ageTextField.setText("");
emailTextField.setText("");
cellTextField.setText("");
nameTextField.requestFocus();
}

Here's a link to it : [URL] ....
The basic gist is it's "A program that reads in a text file that uses a specific input format and uses it to produce a formatted report for output."
Specifically :"For this lab you will write a Java program that produces a simple formatted report. The program will prompt the user to enter a file name. This file must contain information in a specific format (detailed below). Each "block" of the file contains information for one player in a competition -- the name of the player followed by a number of different scores that that player achieved. The program should find each player's average score, median score and best and worst scores and display them in a line on the final summary report. The program should also determine which player has the highest average score and which player has the lowest average score."
I get the following errors when I try and compile it:
Enter an input file name: Project11.txt
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException... -1
at java.util.ArrayList.elementData(Unknown Source)
at java.util.ArrayList.get(Unknown Source)
at Project11.getMedian(Project11.java:68)
at Project11.main(Project11.java:27)
I get that the error(s) reside in lines 68 and 27, among problem other areas, but I'm not exactly sure how I can fix them.
Here's my code:
import java.io.*;
import java.util.*;
public class Project11 {
public static void main(String[] args) throws IOException{
Scanner in = new Scanner(System.in);
System.out.print("Enter an input file name: ");
String input = in.nextLine();

I need to count external hyperlinks to other web-sites on each page of the the web-site. I've found this code here on stackoverflow:
public class Scanner {
private HtmlProcessor hp;
private String baseUrl;
private int step = 0;
private List parsedLinks;
public Scanner(String baseUrl) {
[Code] .....
Also I've found other working code that uses standard Java but it counts links only in one web-page. Can't create pattern to look all pages on web-site yet.

Introduction: There is a glossary table of English and French words. The glossary table has duplicate rows and is out of order. I would like to remove the duplicates and sort them by the English column.
1. Open the glossary.html file in your browser, you will see a table on the left with an English column and a French column. On the right hand side of the screen you will see the unit test results. As you complete each TODO the unit tests will pass.
2. There are five areas marked TODO in the glossary.html file,
complete all of the TODOs. Check that all of the unit tests pass. This test project uses the following frameworks:
* BackBone.js - [URL] ...

I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.
// QR Code Generator
package qrcode;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.border.EtchedBorder;
import javax.swing.border.TitledBorder;

I have a program that reads lines of text, but some of the lines of text aren't applicable and break the program. I'd like to put a letter in front of the lines in the .txt file I want to use, such as a #.
I need to make an if loop that'll check for the first letter on the line being #, and use the line in the program if true and skip if false. I'm guessing a boolean variable would be useful here to be true or false depending on the presence of #, but I don't know how to only read the first letter of each line, how can I do this?

I am checking how to do following task.
01. pickup the selected text file and read the line by line and output the text in to visual text pane.
what i did:.
01. I wrote code that read the text file and output in to jave console/ also some of the interface.
the code read txt file:
Java Code:
String fileName = "C:/Users/lakshan/Desktop/lawyer.txt";
File textFile = new File(fileName);
Scanner in = new Scanner (textFile);
while(in.hasNextLine()){
[code]....
so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?

I am trying to read a text file into Java and split the text into tokens. Eventually I want to be able to count the number of instances of a specific word. However, at this point, when I run the file, all I get is the location of the file rather than the text in the file.
import java.util.*;
import java.io.*;
public class textTest3 {
/**
* Prints the number of words in a given file

* @param args
* @throws IOException

I must convert some Java fubction to a plain "Basic", as VB6. The problem I'm facing is this: Suppose I have an array like
Java Code:
private static final int[][] Terms = {
{193, 26, 13},
{183, 29, 14},
{170, 20, 11}
}; // total 659 terms mh_sh_highlight_all('java');
How do I populate the Terms array?
Is it:
Terms[0,0]=193;
Terms[1,0]=26;
Terms[2,0]=13;
Terms[0,1]=183;
Terms[1,1]=29;
Terms[2,1]=14;
Terms[0,2]=170;
Terms[1,2]=20;
Terms[2,2]=11;
?
I'm not sure this is right... Is there a way to automate this process? What if we have arrays like int[][][] Terms? This is terrible... Is there a software tool for this?

a. Write a code that is written inside a body of a method named average that takes two parameters: N that determines number of terms you should calculate the average of and lowBound that is the beginning term of the geometric sequence. if lowBound is 4 and N is 3, then the average of 4, 8, 16 is calculated and returned.
My code runs fine if I set the test as 16, but I can't figure out what I could do to N to have it determine the number of terms. This is what I have so far...
public class AvgIt {
public static void main (String[]args) {
double result = average(4, 3);
System.out.println("Average is " + result);

I am not sure what is wrong with my code? The code produces a negative number when I type in 4000000 into the fib method parameter.
Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:
1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...
By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
Java Code:
public static void fib(int k) {
int result = 0;
int[] array = new int[k];
array[0] = 1;
array[1] = 2;
for (int i = 2; i < k; i++) {

I have just started learning Java from a local teacher, this teacher said that the Architecture Neutral refers to Hardware while Platform Independent refers to Operating System, but I found a link to a White Paper by James Gosling. The chapter 4 of this White Paper mentions about both binary code format that is independent of hardware architecture and operating system interfaces, but the main point to be noted is that he has put both under the heading Architecture Neutral. Does it mean that the original buzz word is Architecture Neutral, which includes both hardware and operating system independence?

I have seen many ways of describing what objects are, one being that objects are a user-defined datatype. However, if objects are datatypes, then what does that make classes? To me, it seems as though classes should be the "types" of data defined by the programmer, and objects should be the specific "values" of that user defined data type. As an example, an integer would be a class, while 1 would be a "value" of that class, i.e. an object. From this point of view, I don't see why a specific number would be a data type... Therefore, why do we say that objects are user defined data types rather than classes?

I am able to generate text boxes. But I need one specific thing in that:
Through a drop-down I should select a number and those many text boxes should get generated.
Suppose I selected 4 from the drop down list. Then on screen it should display:
Student 1: Textbox
Student2: Textbox
Student3: Textbox
Student4: Textbox
