I need to break it and #numbers in braces are assigned to string array and they should cal by one by one. similarly next level on calling #166 same operation should perform
{#166=ADVANCED_FACE(",(#165),#129,.F.);}
like this 8 levels were there, finally at each level the Calling number should display in JTable.
I am supposed to read in a file and extract the data. I am trying to add a Long into an Array that I initialized. So this is how my method looks like :
Java Code:
public void readOSMWay(File osm){ try { Scanner output = new Scanner(osm); while(output.hasNext()){ String line = output.nextLine().replace("^s+",""); if(line.startsWith(" <way")){ Road way = new Road(line,true);
[Code]...
I am having problem with the else if block. I am supposed to add all the Long values into the array.
error: Java Code: The method add(Long) in the type ArrayList<Long> is not applicable for the arguments (String) mh_sh_highlight_all('java');
Pass each index each time to a method returning all rows but getting stuck with DS to use. I think ArrayList wont suffice since i need separated data. Should i use a 2D array? Do i need to read and store data in a DS in order to achieve the goal?
2) Should i make 3 different classes with getters and setters for authors, book and magazine?
I'm trying to figure out the necessary code for reading integers from a text file, then placing them withing the two-dimensional array I have created, and then finally printing the array using a nested for-loop. I have attached the file I would like to read from. I'm having trouble figuring out how to reference the text file with the integers, and also how to properly create a dynamic preface for each row of the array. I want the preface to display as "Week #: ", with # being the row number. I tried to create an integer to be used that way, but NetBeans tells me whatever integer I declare has already been defined in method main. I know I need to use scanner to read the file. I would like the output to display like this:
how can I extract data from two different files but produce one output. For example, the first three columns are from text_file_1 and the last column (the last foruth column of the output) is from text_file_2.
New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows
(1) The original list of N numbers from the input file, (2) The original list of N numbers printed in reverse order of how they appear in the input file. (3) The sum and average of these numbers, (4) The minimum of all the numbers, (5) The maximum of all the numbers.
my idea is auto recognize when i put image like survey and that survey has shape box and it random area location and some shape box also character and number and can generated data that recognize in csv file.
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?
Write a program that reads in a line of text and then outputs that line of text first in all uppercase letters and then in all lowercase letters.
INPUT and PROMPTS. The program prompts for a line of text as follows: "Enter the text: " and then reads in an entire line of text as a String .
OUTPUT . There are four lines of output . The first line is "The text in all upper case is: ". The second line is the line that was read in, displayed in all uppercase. The third line is "The text in all lower case is: " and the fourth line is the original line that was read in, displayed in all lowercase.
CLASS NAMES. Your program class should be called ShoutAndWhisper.
This is what I have so far:
import java.util.Scanner; public class ShoutAndWhisper { public static void main(String[] args) { Scanner scannerObject = new Scanner (System.in); System.out.println("Enter the text: "); scannerObject.next(); System.out.println("The text in all upper case is: ");
I am working on a personal project and want to create a text editor to write my code. I am wondering how could I read the last input from the user and if say it was an open curly brace {, then like netbean's my editor will supply the closing curly brace. My java experience is limited but I have tried to read key board input and a few other options that did not work.
I would like to have one horizontal scrollbar control the scrolling of two JScrollPane objects (each of which contains a JTable with similar models). The line of code that I hoped would give me what I want is this:
It does exactly what I want, except that the scrollbar appears on-screen in the spUpper JScrollPane, while the spLower JScrollPane no longer displays a scrollbar at all. That's the opposite of what I expected. Apparently, spUpper's setHorizontalScrollBar is "stealing" spLower's scrollbar.
An alternative is just to have each scrollbar use the same model, like this:
This links the two scrollbars such that either will control both JScrollPanes (and also the other scrollbar), but it leaves them both visible, which is not what I want. I would have thought this line would make one of them invisible:
The full code using the first approach is below. My questions are these:
Am I correct that setHorizontalScrollBar not only sets which JScrollBar will control a JScrollPane, but also determines where it appears on the screen?If so, what happens to the original JScrollBar? Is it replaced or am I drawing one on top of the other (or something else)?Why doesn't setVisible(false) make the scrollbar disappear (and how can I do that)?

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'm supposed to write a GUI application letting the user enter a file on the text field and display its hex representation in a text area and vice versa.
Here's my code:
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package hexconvertor; import java.util.*; import java.io.*; public class HexConvertor extends javax.swing.JFrame {
I'm working on a simple text editor, and I'm currently saving the contents of my JTextPane in a file using an HTMLEditorKit (text is a JTextPane):
private void save() throws IOException { int returnVal = fc.showSaveDialog(window); if (returnVal == JFileChooser.APPROVE_OPTION) { StyledDocument doc = (StyledDocument)text.getDocument(); HTMLEditorKit kit = new HTMLEditorKit(); BufferedOutputStream out;
[Code] ....
The problem I'm having is that after opening a file that I saved, it does not display (if I disable text/html, it displays the entire html code, but when I re-enable it, nothing displays at all.) Am I loading it wrong, or am I setting the JTextPane's text incorrectly? Or is it, perhaps, another error that I didn't catch?
Write a program that reads an integer and displays, using asterisks, a filled diamond of the given side length. For example, if the side length is 4 the program should display.
* *** ***** ******* ***** *** *
I have it where it displays the top half of the diamond. But i cannot figure out how to get it to draw the bottom half.
import java.util.*; public class E616 { public static void main(String[] args) { Scanner input=new Scanner(System.in); System.out.print("Enter number of rows. "); int N=input.nextInt();
You may assume that all values are positive. First figure out the maximum value. That value's bar should be drawn with 40 asterisks. Shorter bars should use proportionally fewer asterisks.
import java.util.Scanner; import java.util.ArrayList; import java.util.Arrays; public class Array717 { public static void main( String[] args )

The problem is that all this code does is print 1 line of *'s and what seems to be thousands of them
personid gender height class 1 female 1.6 short 2 male 2.0 tall 3 male 1.85 medium 4 female 1.9 medium 5 male 1.7 short 6 female 1.8 medium 7 female 1.95 medium
for eg i have to find minimum and maximum height from column height.
I have to write a program for sorting an array of random numbers by the users choice. These random numbers are stored in a text file, which the user inputs, and is then stored into an array for sorting. I won't have a problem with the sorting algorithms, but I've never had to read a text file and store it into an array before
The text file has the numbers stored like so : 148 626 817 4 312 652 643 etc....
I gather that I'll probably have to user the Scanner for the user to input the text file name, but how do I store it to an array? So far I only have the bones of the program done, like so
import java.util.Scanner; public class SortingAlgorithms { public static void main(String[] args) {
So I am saving a file. it is an array of two strings each containing three words. i figured out how to save to a text file and read it back in and put it back into an array. I am using scanner.hasnext and scanner.next and i think that separates the strings into variables using the spaces in the strings. Well for my project i need to do it with a symbol instead of a space
I am trying to read in lines of text from a file then prints out the text. I only need one 2D array and can't copy from one array to another.This how the file looks like:
4 4 FILE WITH SOME INFO
I have been able to read the file but when I am trying to run my program I have blank spacing instead of an array.
import java.util.Scanner; import java.io.*; public class Array { public static void main(String[] args) throws IOException{
Write a class TextAnalysis14 which reads a text file and allows some text mining(Analyzing). Concretely the program has to support
1. total the number of words, 2. checking whether a word is contained in the text, 3. finding the most frequent word, or words in case there are more than one.
A word is a non-empty string consisting of only of letters (a,. . . ,z,A,. . . ,Z), surrounded by blanks, punctuation, hyphenation, line start, or line end. The analysis is case-sensitive.
I've written a program to read files in a directory but I'd like for it to only read the text files of that directory.
import java.io.*; public class Data { public static void main(String[] args) throws IOException { String target_dir = "C:files"; File dir = new File(target_dir); File[] files = dir.listFiles();
