ArrayList - CSV File Parsing

Nov 18, 2014

I have to read this CSV file into an arraylist. Arraylist i call weight. The data in the csv file has 200 double values which is the weight of all the 200 bananas. Since the csv file is a string i guess I cannot create an double arraylist from scratch, but i have to parse the csv file afterwards, right? Well this does not work and ill show you the code in a bit, just need to state all my issues.

My second issue is how to be able to print out the the weight items (in this case bananas) next to the weight of the bananas taken from the array? This has to be done by constructor i assume? I just dont know how constructors work with arraylists.

Id like it to look something like this in the output window.

Banana 34,55
Banana 43,55
Banana 23,74

and so on (200 times)

so these are my issues, how to parse and how to print the arraylist weights and the item banana in the output window with constructor. Here is the code.

package Main;
import java.io.BufferedReader;
import java.io.FileReader;
import java.util.ArrayList;
import java.io.IOException;
import java.io.Serializable;
import javax.swing.JOptionPane;

[Code] ...

Reached End Of File While Parsing

public class DemoBlock{
public static void main(String[] args){
System.out.println("Demonstrating block scope");
int x = 1111;
System.out.println("In first block x is " + x);

this is the error I'm getting..reached end of file while parsing. I think this is referred to as either an extra curly brace or that I am missing a curly brace but I'm not 100% sure.

Parsing Input From A File Using Scanner

Mar 26, 2014

I'm having some kind of weird problem reading input from a file. It says that my scanner object I'm using to hold an item of information isn't initialized, when I do try to initialize it, it says error variable already initialized. I'm using the scanner to read input from a file whose contents are this

10
150.4
88.4
-3.14
499.4
799.4
1299.8
0
1900.2
901.7
4444.4

This is my program

import java.util.*;
import java.io.*;
public class QudratullahMommandi_3_07 {
  Toolkit_General toolKit = new Toolkit_General();
  public static void main (String[]args)throws IOException

[Code] .....

This is the error message

QudratullahMommandi_3_07.java:34: error: variable holder2 might not have been initialized
String holder2 = holder2.trim();

1 error

Parsing CSV File - Column And Row Data?

Dec 19, 2014

I am trying to merge two files together using the Apache Commons CSV library. I figured it was easier to use this than to write my own implementation.

The first problem is that the output contains the underlying class logic and as a results my output contains a bunch of un-needed data. How do I get rid of this? I just want the column and row data, nothing else.

Example

I want this:

customerNo, firstName, lastName, birthDate, mailingAddress, married, numberOfKids, favouriteQuote, email, loyaltyPoints
1, John, Dunbar, 13/06/1945, 1600 Amphitheatre Parkway Mountain View, CA 94043

But I get this:

CSVRecord [comment=null, mapping=null, recordNumber=1, values=[customerNo, firstName, lastName, birthDate, mailingAddress, married, numberOfKids, favouriteQuote, email, loyaltyPoints]]
CSVRecord [comment=null, mapping=null, recordNumber=2, values=[1, John, Dunbar, 13/06/1945, 1600 Amphitheatre Parkway
Mountain View, CA 94043

The second problem is that I just want the row Headers from the first file, but the row headers from my second file are still being included in my output. I used withSkipHeaderRecord(true), but it didn't have the desired results.

Code is below.

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Reader;
import java.util.ArrayList;

I thought of processing line by line using scanner and then split each line in the ":" . But then i stuck, i only need the right part of the ":" so that i can save it to a class e.g. John Doe, 133456593, married etc.

Java Code: Name: John Doe

Write And Read Via ArrayList With Text File?

Feb 6, 2015

I wanna learn to create a method where I use a scanner or any other way to input.The stuffs I input will be strings. The whole thing will be like a destination creator.So if I input the string USA, it will write this to a file:

1:USA

When I go to the method again the ID will be added so if I input UK, the file will contain:

1:USA
2:UK

Now if I terminate the program, next time when I run it again it will be able to read the ArrayList, so if I wanna go to the method again and write: Norway the file will contain:

1:USA
2:UK
3:Norway

Later I also want to be able to use println to show all of these lines from the file, as well I would like to be able to delete an ID, so if I delete ID 2 the file would contain:

1:USA
3:Norway

I'm quite new to Java, I'm in a Java course since soon 3 weeks back and I have sure learned a lot, all the loops and basic statements that exist in most languages, but now when it comes to this I just don't understand.

Text File - No ArrayList Or Comparator Is Allowed

The collateExams method collates/sorts exam objects starting with the first 'm' (midterm) of the first object and immediately followed by the same person's 'f'(final). Only a SINGLE loop construct is allowed. The output from collateExams() should be the one below but my code is not working, i.e. collateExams method is not working. The output from collateExams() should be

I am advised to use a while loop the Scanner method hasNextLine() and in the while loop body, call the Scanner method nextLine(), and add the returned String to the ArrayList of Strings. what I have gotten so far:

Scanner input = new Scanner(new File(""));
while(input.hasNextLine()) {
String line = input.nextLine();
System.out.println(line);

DOM Parsing Method

Feb 26, 2015

I've been staring at my code for the past few days and I just can't get it to work out. I'm trying to parse a DOM object with the following XML loaded:

<?xml version='1.0' encoding='UTF-8' ?>
<form>
<record event="boot" date="2013-11-01">
<text>system boot</text>
</record>
<record event="login" host="localhost" date="2013-11-01">

[code].....

I'm trying to get all of the attributes that I care about out of the <record> tags (date, event, etc ...) and stick the data in a wrapper class (DocumentData). If you run this, you'll see that it is close to working, but I'm having trouble getting the attributes in the <subject> and <return> tags (I need to get the errval and uid attributes).

Parsing A Value From A String

Jul 1, 2014

I'm simulating temp/humidity values and want to separate the string value reported and parse each part (left and right) for their respective values. However, I'm having trouble figuring out how to parse the right hand side of this string value, I can get the left using split (shown below), but I think split removes the right hand side of the string value.

the value reads "Temp=22.9*C Humidity=50.9%"
Java Code: private Double parseTemperatureFromString(String consoleOutput) {
String[] tempHumidParts=consoleOutput.split(" ");
String[] tempPart=tempHumidParts[0].split("=");
String theTemp=tempPart[1];
theTemp=theTemp.replace("*C","");
return Double.parseDouble(theTemp);
