This is actually my question:
Java Code:
1. billing-20140527[09].txt has
a)XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
b)XGMS,2034-05-27 30:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
2. billing-20140527[10].txt has
a)XCGS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
b)HELO
[B]I try to find the number 1 in both text files, if lets say I input the text file name is billing, I can find the number 1 in both text file and output them:[/B]
a) XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
b) XCGS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
[B]However, if I specify the text file name: billing-20140527[09].txt and find the number 1 inside the text file, it will only output:[/B]
a) XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040. mh_sh_highlight_all('java');
This is the code that I wrote but I have two problem with two buttons one of them ... I want to delete the selected text inside the text Area which represented as b[8] and the other button that I want to select parts of the texts which represented as b[0]....
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 just can't seem to figure it out how to solve this inherently recursive assignment.The task is to check a directory path and read the files within that path; also, if there are more directories within it, we have to go deeper into those directories to read the files within them - if any. What you're looking at is my skeleton of the assignment:
public class SearchingForStrings {
public static void main(String[] args) { String path = "."; // Default File sf = new File(path); String mainDirectory = args[0]; // These two are just String keyString = args[1]; // command-line arguments
Trying to find cheapest path recursively, given a grid a integers trying to recursively find the cheapest path from the top to the bottom. cheapest being the sum of the path. I think I've made my code over complicated. recursive things are usually much more elegant
import java.io.FileInputStream; import java.util.Scanner; import java.io.FileInputStream; import java.io.FileNotFoundException; public class trial { public void readFile(String fileName)
I have to recursively find a given string in a file. I HAVE to use the LineNumberReader class, and the output would be like so:
Line#Found : the string of the whole line
This is the code I've written:
public String findGivenString(String givenString, int currentLineNumber) { LineNumberReader lnr = null; try { lnr = new LineNumberReader(new FileReader(getFile()), 4096); lnr.setLineNumber(currentLineNumber); String s = lnr.readLine().toLowerCase();
[Code] ....
I messed around with a bit, and it doesn't change to the new set line. Though the line number is incrementing! So it just keeps checking the first line of the file over and over again, which is why it can't find the given string. Which also throws the StackOverFlow exception I'm getting.
Here's the output if I remove the comment from the System.out...:
String @ that Line# 1: package banking; String @ that Line# 2: package banking; String @ that Line# 3: package banking; String @ that Line# 4: package banking; ....
So you see it keeps checking the same line even though the line number IS incrementing.
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.
**Here is my question. I'm trying to use input and loop method to search for a file. The above code works but my problem is lets say I try to find 2 different text files**
1. billing-20140527[09].txt has
a)XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040. b)XGMS,2034-05-27 30:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
2. billing-20140527[10].txt has
a)XCGS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040. b)HELO
I try to find the number 1 in both text files, if lets say I input the text file name is billing, I can find the number 1 in both text file and output them:
a) XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040. B)/> XCGS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
However, if I specify the text file name: billing-20140527[09].txt and find the number 1 inside the text file, it will only output:
a) XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
How can I do so? Because I can output the number 1 from both text files even though I specify the name.
I'm refitting a snippet of code I found on the net to write stuff into text files. After a bit of fiddling, here's what the code looks like in one of my classes:
public void addItem(String Item){ try{ Writer out = new OutputStreamWriter(fos, "UTF8"); out.append(Item); out.flush(); // out.close(); } catch (IOException e) { System.out.println(e.toString()); } }
The original snippet included the close() method. However, when I tried to do a test run writing multiple lines, I'd get an IOException about the stream being closed. I removed the close() method line, everything seems to work the way I want it, but I just wanna know if there's anything I'm missing out on by not having the close() method anywhere, especially when the IDE finds it important enough that it lit a warning about the stream not being closed somewhere as I was repurposing the original snippet.
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();
I just went over how to open and edit text files in java. Was wondering how to open mp3, mp4 and other media files, is there a special package i need to import or plugin that I need to install in eclipse?
Why is it simple for a word processing software (one that reads number of words, words greater that x characters etc) to deal with text file(.txt) and not with a doc file (.doc) file?? Is there any special requirements or what are the points taken into consideration while developing the software for a .doc file?
I've been trying to write a program for some time now, but im encountering problems while trying to complete it. The program has a student class and a course class (set up with some info about the class, like #, professor name, course title, course time). Now, i have a text file in the workspace, and i have to import the data from the textfile, and thats just what i did, but then there is an option which allows the user to delete a course only by inputing the course number, and when he does that, the program outputs the course's name, and confirms the deletion of the course (From the student's record, i created a vector for that and imported all the courses from the text file). But how can i let the program know what's the name of the course when the user inputs the course number ???
When the data is read from the file, objects should be created and added to the student's course record. <- i think here's where i messed up ? i imported the data, but how can i actually make them objects before adding them into the vector ?
PHP Code:
public static void main(String[] args) throws IOException { Scanner scan = new Scanner(System.in); Vector Record = new Vector(); try {FileReader filereader = new FileReader("CLASSES.txt"); BufferedReader bufferedreader = new BufferedReader(filereader); String test = ""; while(test != null) { Record.addElement(test); test = bufferedreader.readLine(); } mh_sh_highlight_all('php');
I am trying to split the contents of the text file and assign the value on the left of the separator to a variable and the value on the right of the | separator to another variable. Thus I tried out a sample code to print all the values in the split [] first, and ended up with problems. This is the content of the text file:
Crazed Boy|20 Hello|5 MSB|6.5
public class Main { public static void main(String[] args) { try { BufferedReader infile = new BufferedReader(new FileReader("test1.txt")); for (int i =0; i < 3 ;i++) { String s = infile.readLine(); String[] ss = s.split("|");
[code]....
I keep getting IOException in my sample code, why is this so ? I assumed the split() method is supposed to output for the 1st iteration:
I need to read the contents of file A, and B and store it in file C by joining the contents of A and B and also counting the number of letters/characters present in it.
I've come up with this so far.
import java.io.FileInputstream; import java.io.FileNotFoundException; import java.io.IOException; public class JavaApplication43{ public static putwrite(string fname) throws FileNotFoundException, IOException
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 can't make the [JfileChooser] save text file instead of opening files.that [ComboBox] always don't show me the items that i have inserted in eclipse.
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();
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 have a textField in which I have text in. The text is enter customer name. I would like for this text to disappear whenever the user clicks on the textField to enter a customer name. I am using the automated swing gui builder in NetBeans. Is their some sort of feature for this under properties of the text field? If not then what are my other options?
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'm using JBoss 7.1.1.Final. I'm writing a Spring 3.1.1.RELEASE web application and have a massive amount (~5MB) of text output to send to the browser. I would like the browser to display the output as it is generated, but right now, the browser only displays everything after the servlet's doGet method completes. Here's my method …
