I/O / Streams :: Reading A File Line By Line And Deleting It

Oct 15, 2014

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;

Pickup Selected Text File And Read Line By Line And Output Text Into Visual Text Pane

Dec 12, 2014

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?

New Line In Text File

Jun 9, 2014

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

Writing Text To File - How To Append New Line

Jan 11, 2015

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.

Scanner Only Reading First Line Of Text File?

Feb 6, 2015

I have a code that imports a text file [URL] .... and has a variety of methods for sorting through it. The file is structured differently when loaded into the environment, as each line begins with a movie and lists all of its actors. Each line has a movie title, then its release date in parentheses, and then the actors in the movie all listed and separated by slashes (Ex: /lastname 1, firstname 1/lastname 2, firstname 2/etc.....

Well I tried to create a method to search all the actors in the file for an inputted word and return the ones that have that word somewhere in their names. I managed to get it to work, but the code only runs for one line of it. How should I get this to do what its doing, but for EVERY line?

Code is here: [URL] ....

I/O - Read 11 Values From A Text File / Each Value On Separate Line

Mar 26, 2014

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.

Read Line Of Text And Output Text First In All Uppercase And Then In Lowercase Letters

May 29, 2014

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();

How To Make File Reader Object Move To Next Line If There Is No More Input On Line

Feb 18, 2015

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

How To Make A Text File Only Use Lines In A Text File Beginning With A Certain Letter

Mar 15, 2015

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?

SAX Parser / Tags And Text Don't Line Up

Feb 9, 2015

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.

xml file:

<?xml version="1.0"?>
<project
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"

Application That Reads In A Line Length Followed By Individual Lines Containing Text

Jan 9, 2015

I'm currently learning Java and have been set an assignment that requires me to do the following:

Write an application that reads in a line length followed by individual lines containing text. No input line will be longer than the read in line length. In the text lines each word will be separated by a single space. The lines of text to be reformatted and then output so that the output lines of text have straight left and right margins. The last printing character in each line will be at character position (line length). In the text output the character '.' is to be used to represent the space character.

I'm trying to take this task on, but I'm unsure as to what exactly I'm supposed to do with part of it. For one of the methods I need to "work out how many extra spaces will need to be added to make the line width characters long.", how would I go about doing this?

Read File And Input Each Line Of File Into Array

Mar 21, 2015

I am trying to read a file and input each line of the file into an array. I have not set the array size as I was hoping to fill the array using a while loop. Unfortunately the scope of the array does to work inside the while loop so I am being told that the array 'students' has not been initialised even though it has just outside of the while loop. Is it possible to do what I am trying to without having the array initialised in the while loop as surely the array will be reset every time if it was in the while loop? Here is my code:

public static void students(String file) throws FileNotFoundException {
try {
File studentInfo = new File(file);
Scanner input = new Scanner(studentInfo);
String[] students;
