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 have written the code to read the line from file and save first string as word and and remaining string as meaning..
E.g.: innovation a new method, idea, product, etc.
word = innovation
meaning = a new method, idea, product, etc.
In my code there is no error and have a mistake what it is means first assigning word is ok and while saving meaning ..it saves like
{
a a new a new method } like that
Java Code:
import java.io.BufferedReader;
import java.io.FileReader;
public class Dil{
public static void main(String[] arg)throws Exception
{
BufferedReader in;

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: ");

So I'm trying to read 11 values from a text file, each value on a separate line. The first value I use as loop control to run through calculations on the other ten and finally output both the numbers and the calculations to the console and an output file. I'm not getting a compiler error or a runtime error but my loop seems to stop after reading the first line. It also doesnt seem to be writing to my output file but does create it when I run the program. This is what my text file looks like
10
150.4
88.4
-3.14
499.4
799.4
1299.8
0
1900.2
901.7
4444.4
This is what my program looks like
import java.util.*;
import java.io.*;
public class assignment7scratch
{
Toolkit_General toolKit = new Toolkit_General();
public static void main (String[]args)throws IOException
[Code] .....
so I dont get an error but this is what my output looks like
----jGRASP exec: java assignment7scratch
This program reads a list of values representing number of miles driven by individuals. It will output the dollar amount their rental cars cost.
Number of miles traveled on the left as well as amount reimbursed on the right
-----------------------------------------------
Miles Driven Amount reimbursed
150.427.072
----jGRASP: operation complete.
it also doesn't write anything to my output file, though it does create one.

how to read file line by line ? Namely my input file I want to read look as follow:
AAA 1, 1
12 222 12
AAA 2, 2
11 122 11
My output file should look as follow:
1, 1, 12
1, 1 222
1, 1, 12
2, 2, 11
2, 2, 122

How do I make the file reader object move to the next line if there is no more input on the line. Here is my text and output file as you can see that my text file column cuts off on the 2nd line after 70. I want to read that next line which is 100 into my labs variable however its reading it into my final exams variable. I'll also post the code but I didn't think it was necessary.
textfile:
100908095
1008070
10070
output:
Labs Projects Tests Final Exams
100908095
1008070100
70
[import java.util.Scanner;
import java.io.*;
public class MyGrades
{
public static void main (String[] args) throws IOException
{
int lab, project, test;
int finalExam;//Par and Player values
[Code]...
not sure if I code wrapped it correctly

If I want to read my file line by line and when it hits a certain value from that point it should start deleting the lines until the tag ends.Just curious will my code actually work at the moment or not because it goes through so many times then goes straight back to the variable declarations at the start of the method and never hits the console print line.
public void removeEnvironment(){
//declare variable to environment id
String environmentID = "Environment id";
String lines = null;
boolean lineFound = false;
boolean end = false;

I'm creating a program that searches a txt file for a given string, then return the number line and the line itself. However, my testFile class isn't detecting my searchWord methods.
The searchWord and recursiveSearch is written in a java class called BasicFile
public List<String> searchWord(String key) throws Exception {
LineNumberReader lnr = new LineNumberReader(new FileReader(f));
return recursiveSearch(lnr.readLine(), key, lnr);
}
public List<String> recursiveSearch(String currentLineText, String key, LineNumberReader lnr)
[code]....
Is it because I'm using a list instead of a string?

I'm doing an assignment for uni and have come across a small hiccup. What I'm trying to do is scan in a text file and read "commands" for it line by line, E.g:
Student Mary 12345 19
Student Joe 12346 19
Change Joe 19 20
Change Mary 19 20
So that lines that begin with the word "Student" indicate that I should create a new student file with that name, student ID, and age.
"Change" indicates that I should be changing the specified student's current age to the new age etc.
What I'm currently doing is something along the lines of this:
Scanner input = new Scanner(new FileReader(args[0]));
String[] line;
while (input.nextLine().startsWith("Student")) {
line = input.nextLine().split("s+");
[Code] ....
The problem I'm having is that every second line seems to be getting skipped (because I'm calling nextLine() so much?) but I can't think of a way to "peek" at the first word of each line without advancing past it. Is there any way of doing this?

[new lines]
14-08-3010:20Arizona50.03Scientist

//This line should not be read
even this should not be read #$%^&
11-07-1009:20New York25.00ColdPlay
That particular line should be escaped. Till now I have done when the file format is proper, and it is as below:--
public static void main(String[] args) {
BufferedReader br = null;
String temp = null;
List<String> arrayRead = new ArrayList<String>();
try{
br = new BufferedReader(new FileReader("D: estingSalesData.txt"));

I'm trying to print the information entered into my TimeClockApp to a text file named timeclock.txt. Everything is writing to the text file, except instead of adding each part of the run through the app to one line, it is saving each part on a separate line like this:
i
3
2014/06/08 15:32:29
To ensure that each run through the time clock is recorded on a different line in the text file, I want it to add each item like this instead:
i 3 2014/06/08 15:32:29
I have tried to execute the
out.println(timeClock.get(i)); line as out.println(timeClock.get(i) + " "); and out.println(timeClock.get(i) + "
");,
but have had no luck in fixing this problem. My current code that writes the information to the text file is as follows:
// write items to timeclock.txt file
try {
// open an output stream for overwriting a text file
PrintWriter out = new PrintWriter(
new BufferedWriter(
new FileWriter(fileName))); // (filename, true) when

I am trying to complete this question. I understand the most of it but I haven't go a clue to read in the file name.
Full question: Implement a program that reads in a Java source code file and checks to see if it has balanced {}brackets. Your program should use a stack, implemented as a linked list, to check the brackets.
NOTE: you can use a reference called top which points to the head of the list. Your program should run as a command line program and should take a filename as an argument and print one of BALANCED or NOT BALANCED.
For example: c:> java checkBalanced "myProgram.java" BALANCED

how to use SAX Parsers. I've looked at a few tutorials and have the generals down. I have an xml file that the parser is trying to read. As you see below, at the start of each element, I add the tag to an arrayList of the tags. I create a stringBuilder to capture the text between tags, this won't work unless it occurs at the end of an element. If it occurs at the start, it never gets the chance to read the text.
This is where the problem occurs. For nested tags, like project, it reads the last nested tags' text and stores it in the text arrayList. Project may be the first indexed tag in the tags arrayList, but project's text is the fourth indexed element of the text arrayList. So when my test print the arrayLists by index, it gets thrown off. I want over tags to store a blank space in the text array, and at the same index of the tag its associated with. How would I do this?
I've tried overwriting the text arrayList, but couldn't get my logic thought out for how to determine if a tag was nested. I always ended up overwriting blank space to each element.

Me and my brother decided to make a relatively simple client/server program where clients get into a simple chat lobby and can invite others to play small games(like pong). The basic server code has been written, and we have made a special client that is used for debugging.
We use a self-defined protocol of Strings where a message looks like "4-|user,pass". The number before the delimiter "-|" is the operation code, that tells the server what kind of message this client sends. Based on that number, the server dispatches the message to the appropriate handler method. 4 is authentication for example, and the handler looks the user and pass up in a file and if found, returns true, otherwise, false. Then the server responds to the clinet with 2-|"any message" where the client will recognize opcode 2 as a "authentication accepted" and proceed with the next part of client code. In a similar way, we plan to write all message types(both in the game, in the lobby and in a game setup room).
While testing we ran into a problem where the BufferedReader .readLine() does not seem to be a blocking call like it should be, so the client keeps spamming 'null' in the output field that we made to see the server response to the message we send. When we try to debug the server code and set breakpoints at the suspicious locations, it strangely skips both while(true) loops without activating either breakpoint and executes the finally{} code, even though the client did not close the connection and the second while loop was never entered. The first while loop IS entered though, because the test client gets a "0" on its output, which is the server message indicating "please authenticate yourself".
We decided to use messages in a string format and decode it at both sides as it seemed easier than transmitting java objects and making sure they are of the same type, also for reducing overhead as much of possible.URL....
package Chatroom;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;

How to output text to a file, so I had to do my own research on google, but the results I found were confusing. I finally got my code to write to a file, but I cannot figure out how to append a new line. I know what part of the code is incorrect, but I don't know how to fix it. here is what I have right now:
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.Scanner;
public class highscore {
public static void main(String[] args) throws IOException {
[Code] ....
I can see the last two lines are telling the program to overwrite the first input with the second. Of course if I pick a different file name for the second output, I get another file with the second input, but I need to learn how to append as well.
