Read Characters From Txt File / Store Them Into 2D Array And Print Information

Oct 10, 2014

The point of this program is to read characters from a txt file and store them into a 2D array. After this has been accomplished, the information is to be printed in the same manner it is read from in the txt file.

Here is the code I have so far:

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class Main
{
public static void main(String[] args) throws FileNotFoundException

[Code] ....

And this is the error I am receiving when trying to accomplish the goal of the project:

Exception in thread "main" java.lang.NumberFormatException: For input string: "############"
at java.lang.NumberFormatException.forInputString(Unk nown Source)
at java.lang.Integer.parseInt(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)
at Maze.<init>(Maze.java:15)
at Main.main(Main.java:20)

What's going on here and how I can correct this?? The information I am trying to store in a 2D array and then print is this:

############
#.#........#
#.#.######.#
#.#....#...#
#.###.*#.#.#
#...####.#.#
#.#.#..#.#.#
#.#.#.##.#.#
#o#......#.#

Program Should Read File Contents And Store Information In Array Of Golfers

Dec 3, 2014

The main method will drive your program by doing the following:

-Create an array to hold all the individual golfers and par scores (type is Golfer[ ]).
-Prompt the user for a data file containing the Par scores and the player names and score. The format of the input file should look like

Par, 3, 4, 4, 3, 4, 3, 5, 3, 4
George, 3, 3, 4, 3, 4, 2, 3, 3, 4
Paul, 4, 5, 4, 3, 6, 3, 4, 3, 5
Ringo, 3, 3, 4, 3, 4, 2, 4, 3, 4
John, 4, 4, 4, 3, 4, 2, 5, 3, 4

Your program should read the file contents and store the information in your array of Golfers.

Read ASCII Art Map And Store Information In 2D Array

Feb 12, 2014

I've written some code to do this, but it's not working as I expect. This is what the ASCII map looks like:

###################
#.................#
#......G........E.#
#.................#
#..E..............#
#..........G......#
#.................#
#.................#
###################

Here's how I've tried to store the information in a 2D array:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.Arrays;
 public class Map {
 public void importMap() throws IOException{
BufferedReader br = new BufferedReader(new FileReader("map.txt"));
String line;

[Code] ....

But it's not printing out what I'm expecting. It's printing out:

[[#, #, #, #, #, #, #, #, #], [#, #, #, #, #, #, #, #, #], [#, #, #, #, #, #, #, #, #], [#, #, #, #, #, #, #, #, #], [#, #, #, #, #, #, #, #, #], [#, #, #, #, #, #, #, #, #], [#, #, #, #, #, #, #, #, #], [#, #, #, #, #, #, #, #, #], [

What is printed is much larger than what I've copy and pasted but I can't post it all here.

The error I get is:

Exception in thread "main" java.io.IOException: Stream closed
at java.io.BufferedReader.ensureOpen(Unknown Source)
at java.io.BufferedReader.readLine(Unknown Source)

Read Text File Into Array Ask User To Save File And Print Data

Jul 14, 2014

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.

[import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Writer;

Convert Array Of Integers To Array Of Characters And Then Print It Out

Feb 13, 2014

I have double checked this code over and over and I just can't find the problem.

What I'm trying to do is take a file and input it into an 2D array.

Ultimately, I should convert the array of integers to an array of characters, then print it out. The file contains a set of ASCII values.

After printing it out, I should then create methods to manipulate the image produced.

Using 2D arrays is a requirement for this exercise.

I think that somehow I'm overcomplicating this and the solution is a lot more simple than I think, but I can't think of what to change.

The error I am getting is:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 40
at main.main(main.java:17)

Java Code:

import java.util.*;
import java.io.*;
public class main {
public static void main(String[] args)
throws FileNotFoundException {
String[][] data = new String[22][40];

Read Information From File - How To Get Highest Value

Nov 12, 2014

The requirement asked me to write a Java program to read information from the file, display the original information along with the player's average score of the season (one line for each player), and announce who is the highest average-scoring player of the team. But I always only get the highest which show the last player.

Such like the output showed:

Smith 13.0 19.0 8.0 12.0 Player's average: 13.00
Badgley 5.0 Player's average: 5.00
Burch 15.0 18.0 16.0 Player's average: 16.33
Watson Player's average: 16.33

Ask User To Store 10 Numbers In Array - Print In Order Entered And Reverse

Apr 15, 2014

Write a Java program that asks the user to store 10 numbers in an array. You should then print the array in the order entered and then print in reverse order. However, instead of putting all the information in the main, you should use a class called PrintIt. The PrintIt class should have an instance variable that is an array to hold the numbers. You should have a method that will print the array in the order entered. You will also need a method to print in reverse oder. Then create a tester class that asks the user to enter 10 numbers and puts them in an array.

So far I've got this.

public class printIt {
int i;
int [] numArr = new int [10];
public printIt () {
i = -1;

[Code] .....

Output:

Enter a number:

8
34

Forward:

8
34

Reverse:

34
8

end

what i want as an number is being able to print out 10 numbers but this only lets me do two numbers. Why is that so?

I'm doing desktop application about recipes. User can create new recipe, add information. I want to sort recipes, save them somewhere, maybe make it possible to send recipes over network to other users. But I don't know where and how store information about those recipes.

Read Picture And Print Out Number Of Blocks - Counting In Multidimensional Array

Dec 19, 2014

I have to write a program that will read a picture and then print out the number of blocks inside it.

I have to read the picture as a binary matrix of the size r - c (number of rows times number of columns). The blocks are groups of one or more adjacent elements with the value 1.

- Blocks are built exclusively of elements with value 1
- Each element with value 1 is a part of some block
- Adjacent elements with value 1 belong to the same molecule.

We only take into account the horizontal and vertical adjacency but not diagonal.

INPUT:

In the first line of the input we have the integers r and c, separated with one space.
Then we have the r lines, where each contains s 0's and 1's.
The numbers inside the individual lines are NOT separated by spaces.

The OUTPUT only print the number of blocks in the picture.

Example:

INPUT:
7 5
01000
00010
00000
10000
01000
00001
00100

OUTPUT:
6

THIS IS WHAT I CAME UP SO FAR:

import java.util.Scanner;
class Blocks{
public static void main(String[] args){
Scanner sc=new Scanner(System.in);
char ch[][];
int rowNum=sc.nextInt();
int columnNum=sc.nextInt();

I have a file called statecapitals.txt that is read in, I want to store it in either a 2d array or hashmap and select a random state then Ask the user for the name of the capital. Then I want to Let them know if they are correct or not and have a choice to play as many times as they like. When they no longer want to play,I want to let them know how many they got correct and how many incorrect. I am not sure which would be better a hash map or 2d array and dont know where to start with each.

here is what the text file looks like:

Alabama - Montgomery
Alaska - Juneau
Arizona - Phoenix
Arkansas - Little Rock
California - Sacramento

Store Data From A File Into Array Of Type Product?

Mar 17, 2015

public class InputFileData {
/**
* @param inputFile a file giving the data for an electronic
* equipment supplier’s product range
* @return an array of product details
* @throws IOException
*/
public static Product [] readProductDataFile(File inputFile)
throws IOException{
// YOUR CODE HERE
}

This code is meant to be used to read a text file and store the data in an array of type Product[]. I know how to read in a text file and have it sort it into an array, but I've never seen code laid out in this fashion before (specifically "public static Product[]", and I'm unsure how to work with "(File inputfile)". I've looked all over the place but can't find any examples of anything like this.

Also, the code given cannot be changed, as it's that code I have to work with.

I still don't understand how to use it as a whole. For example, do I read the file in the main and have this method read that in and output to the Product class? Do I read the file in this method? I can't work out how to make this work when I have to use this method.

Read Text File Into Object Array And Creating Random Access File

Dec 8, 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] .....

And then here is the data from the text file that i must extract to use to create product objects.

Dill Seed,938,34
Mustard Seed,100,64
Coriander Powder,924,18
Turmeric,836,80
Cinnamon (Ground Korintje),951,10
Cinnamon (Ground) Xtra Hi Oil (2x),614,31
Cinnamon (Ground) High Oil (1X),682,19

These continue for about 40-50 entries, they are not separated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name separated with spaces, then price after a comma, then quantity after the second comma.....

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;

How To Read Text File Into Array

Nov 17, 2014

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) {
