Reading Entire Integer Text File And Putting Inside Array?

Apr 5, 2014

I have an assignment on sorting, i kno i can get the sorting down but im having an issue with inputing the 512 ints in a file into an array. the instructor provided us with a file with 4 equal sets of ints. i tried to make my array of size [scan.nextInt()] and it cuts off the last 21 ints. and skips the first int. how can i get all of the integers in the text file into my array? this is what i have so far. if i hard code the array to size 50000 and then try to print the array it compiles but errors out when running it.

System.out.println("Please Enter text file in this format, XXXXX.txt :");
String file =fileName.nextLine();
Scanner scan = new Scanner(new File(file));
int [] data = new int[scan.nextInt()]; <-------here it skips first int
int count= data.length;
for (int i=0; i<data.length-1;i++) {
data[i]=scan.nextInt();
}
System.out.print(Arrays.toString(data));

rst 4 ints in output are: 501, 257, 390, 478...., supposed to be 492,501,390....and last ints are: ....88, 83, 79, 0 and supposed to be :88 83 79 77 76 72 71 71 66 57 56 48 48 41 33 30 23 23 18 17 15 13 9....it replace last ints with 0. why ? and how do i fix this. attached it the text file

Not Reading Entire File

Mar 29, 2014

I'm new to Java and have not been able to figure this out. I'm reading a text file that contains this:

110001 commercial 500000.00 101
110223 residential 100000.00 101
110020 commercial 1000000.00 107
110333 land 30000.00 105
110442 farm 200000.00 106
110421 land 40000.00 107
112352 residential 250000.00 110

The output goes to a text file and should look like this:

COMMERICAL

FARM
LAND
RESIDENTIAL

101 600000.00
105 30000.00
106 200000.00
107 1040000.00
110 250000.00

I'm creating the output file, but it only contains the categories and not the details below them. Cant seem to figure out why.

Java Code:

package propertylistings;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileWriter;
import java.io.IOException;

Shuffling Array Is Putting Same Integer In More Than One Place

Sep 11, 2014

I have to shuffle a deck (array) of 52 integers but I started with 3 for testing if it was an even shuffle and it will place the same integer in more than one spot in the random array. I'm not sure what I'm doing wrong...

import java.util.Random;
public class shuffleDeck {

Reading Text File Into Object Array And Create Random Access File

Dec 9, 2014

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.....

Reading From Text File - Array Index Out Of Bounds Exception

Oct 21, 2014

I need to read from a text file given to us that has a list of books with authors names and book titles separated by an @ symbol for our delimiter. Here is the code I have right now, but it throws an ArrayIndexOutOfBoundsException at line 7...and I am unsure why?

import java.io.*;
import java.util.*;
public class Driver {
public static void main(String[] args) {
new Driver(args[0]);

[Code] ....

I realize that it must have something to do with my command line argument...but I am unsure what. Am I not entering the file name correctly?

Swing/AWT/SWT :: Putting Text From Txt File Straight Into JComboBox

Sep 23, 2014

I have two classes - One is Read.java and the other is Display.java

Read.java looks like this

public static void main(String[]args){
File file = new File("test.txt");
try{
FileReader fr = new FileReader(file);
BufferedReader br = new BufferedReader(fr);

[Code] ....

Display.java looks like this:

public class Display extends JFrame {
private JComboBox comboBox;
private JPanel contentPane;

/**
* Launch the application.
*/
public static void main(String[] args) {
//method call to access other class

[Code] ....

Instead of having it so it displays the id's to the console,is there a way I can set it straight up to the combo box?

Reading Data From A File And Putting That Data In Arrays

Feb 8, 2015

I am creating a program where it reads the data inside a file and then places this data into arrays. The file I created has numbers 1-30 in it, file named, testing1.txt .

Java Code:

public static void main(String[] args) {
// TODO Auto-generated method stub
// Variables Declaration Section
//******************************
BufferedReader br;
String sCurrentLine;
String str;

[Code] ....

My issue is that the 'str' value is not initialized, but if I initialize it, it ruins the code. I'm not sure what to do in the situation.

Counting The Frequency Of Numbers Inside A Text File

Apr 7, 2014

I have a source code here that counts the frequency of alphabetic characters and non-alphabetic characters (see the source code below).

import java.io.*;
 
public class letterfrequency {
public static void main (String [] args) throws IOException {
File file1 = new File ("letternumberfrequency.txt");
BufferedReader in = new BufferedReader (new FileReader (file1));
 
[Code] ....

But, let's just say that now I have the following characters in the text file, "letternumberfrequency.txt":
71 geese - 83 cars - 58 cows- 64 mooses- 100 ants- 69 bangles- 90 molehills - 87 noses

The numbers inside that text file would be considered as strings, am I right? But I want to extract the numbers so that I can also be able to count their frequency - not as individual digits but as whole numbers (that is how many "71", "83", "58", "64", etc. are there...). Would using "Double.parseDouble ()" work?

Reading Files From A Text File

May 26, 2014

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.

Reading A Text File For A Graph?

May 2, 2014

I'm trying to print the number of vertices in a text file on a graph which is the first integer in the file and then the type of graph is an undirected graph for a 0 or a 1 for a directed graph. Right now I'm just trying to print the number of vertices which is a 6 in the text file.

Here's the text file:

6,1
0,2 0,4 1,4 1,5 2,1 2,3 2,5 3,2 3,4 4,1 4,5 5,1 5,3 5,2
Im getting the following error:
Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 6, Size: 0
at java.util.ArrayList.rangeCheckForAdd(Unknown Source)
at java.util.ArrayList.add(Unknown Source)
at Vertices.main(Vertices.java:21)

Then I need to know how to go about reading the next line in the file, do you read it with the nextLine and put it into an arrayList or do I read each index in the graph?

public class Vertices
{
public static void main(String[] args) throws Exception
{
Scanner inFile = new Scanner(new File("graphs.txt"));
// Read the number of vertices
String line = inFile.nextLine();
ArrayList<Integer> list=new ArrayList<Integer>();
String[] data=line.split("[\,]");
int numberofvertices=Integer.parseInt(data[0]);
int typeOfGraph=Integer.parseInt(data[1]);
list.add(numberofvertices,typeOfGraph);
System.out.println("The number of vertices is " + numberofvertices);
}
}

Reading Text File Output

Mar 16, 2014

I have to write a program that reads the input from a text file!

Beware the Jabberwock, my son,

the jaws that bite, the claws that catch,

Beware the JubJub bird and shun

the frumious bandersnatch.

I should print the number of lines, the longest line, the number of tokens on each line and the length of the longest token on each line.

I was able to find the number of tokes in the line but im having having problems reading the longest word ,, my program gives me the number of letter of each line instead of only the number of letter of the longest word!!

this should be my output:

Line 1 has 5 tokens (longest = 11)
Line 2 has 8 tokens (longest = 6)
Line 3 has 6 tokens (longest = 6)
Line 4 has 3 tokens (longest = 13)

Longest line : the jaws that bite, the claws that catch,

import java.io.*;
import java.util.*;
public class InputStats{
public static void main (String [] args )

Swing/AWT/SWT :: Reading Text File Into GUI

Jul 2, 2006

I am using a JFrame with JPanel (with radiobuttons and jtextfields) and am wanting to get data from a text file (around 100 words) and input 4 words at a time into my gui. I have been trying to do this by filling an string array with the data, (no problems here) then using jTextField to read the array. (having a few problems in this area though) Am about 80% there...but just wondering is there a better way to approach this problem, that is, inputing words into gui, refreshing, input 4 new words, refreshing, etc.

Program Is Not Reading The Text File

Apr 29, 2014

I'm working on a project for my Java class and I've got the code compiled and running, I just don't think that the program is reading the text file the way I want it to.

The text file looks like this:

1168,4.25,10
1305,1.80,42
1345,12.56,16
1388,7.42,30
1480,6.54,80
1495,8.36,48
1560,15.27,65
...

The first number being product number, second being price, and 3rd being quantity. I want to be able to enter the product number and have the Textfields for price and quantity be filled accordingly.

But when I enter a product number (e.g., '1168') no match for the item is being found, regardless of what I enter. Really stumped on this. Here's my code so far --

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.util.Scanner;
public class Project3
{
private static Frame myframe;
private static TextField productCode;
private static TextField invNumberField;

Reading XML File - Get Text Using JAXB

Feb 25, 2015

In my app, I'm reading a xml file (with JAXB) but there is times that I have empty segments. I put some examples :

<tuv> <seg>Unknown: the action taken should always be known</seg> </tuv>

Here I read well the tag "seg", I can get all text "Unknown: the action taken should always be known" but if this text is like this:

<tuv> <seg><bpt i="1" x-wb-tag="b1" />Unknown<ept i="1" x-wb-tag="/b1" />: the action taken should always be known</seg> </tuv>

I don't get anything, my variable is empty and I want to get all text "Unknown: the action taken should always be known"

Could I get this text

"<bpt i="1" x-wb-tag="b1" />Unknown<ept i="1" x-wb-tag="/b1" />: the action taken should always be known"

Or only "Unknown: the action taken should always be known" (without tag "ept" and "bpt"? (I want this like a string)

My variable's value is a "string" ....

Why Is BufferedReader Not Reading But Clearing Text File

Mar 30, 2014

Followed this: [URL]

public static final String FILENAME="BinarySearchTree.txt";
....
public BinarySearchTree(TNode r) throws IOException {
root = r;
textfile = new File(FILENAME);
fw = new FileWriter(textfile.getAbsoluteFile());
bw = new BufferedWriter(fw);
br = new BufferedReader(new FileReader(FILENAME));

[code].....

In the constructor I create the BufferedReader using the FileReader and path to the input text file(in same dir as this project). When I am done reading I close it. In the debugger it is unable to read a single line, then goes to close the file.

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] ....

Reading / Outputting A Text File With Modified Content

Feb 15, 2014

This is sort of like the last problem I had but it's all about the formatting at the end. I have a file that reads something like:

Name
a bunch of text here
and perhaps a second
or even a third line

I need to output this as:

Name; "a bunch of text here and perhaps a second or even a third line"

Right now I find 'Name' and it outputs:

Namea bunch of text here and perhaps a second or even a third line

How would I add ";" and quotes in the middle? I can imagine that I may need to find name, then skip to the next line and just add name manually as the variable output of the search string.

This is where I am now

public static void main(String[] args) {
boolean output=false;
String name="";
String junk="CHAMBERS";
TextIO.putln("Search for a name");
name = TextIO.getln();
TextIO.readFile("doc.txt");

[Code] .....

So I'm almost there, but those dange double Names are killing me. I tried to add a bit of code where:

if (line.indexOf(name) >= 0){}

Reading A Text File And Inserting Line Into String?

Denver
29 F
South, 10 mph
denverimage

and I want Dallas in city variable, 78f in temperature variable, and so on until text ends, at the moment is all goes into city variable, it all prints from there! I tried inserting it into an array but it would read all the lines previous to it in addition to reusing readline and all failed.

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
public class Textreader {
public static void main(String[] args) {
