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.

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;

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 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;
[Code] .....
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
TRN: 133456593

I am new to java coding. so reading the log file using java code.
1) I wish to parse a file, and find a value for variable e.g. [StorageVersion].
2) After finding the value, it will be pushed to database.
Log File Path e.g. C:Temp est.txt"
Sample Logs :
{
//NAME
[1.2.2917] := s['3.4.454545'];
//Parameter
[1.2.2947] := s['1.2.56778'];
//Enabled
[1.2.3910] := B['22.43434.12232'];
//MAXCLOUMNNAME
[1.2.4217] := N['1.7.899982'];
//StorageVersion
[1.2.2917] := K['706146.0.22106932'];
}
From above log file, the Value i need is "706146.0.22106932"
This method keeps throwing a NullPointerException. Not only that, but its not doing what I want it to do.
Heres the code:
/*
Remove all the numbers from the queue and push onto the stack until an operator is reached
*/
private static void processQueue() {
// Check what is at the front of the queue. If an operator is found or the queue is empty, exit method.
while(queue.front() != null || !queue.front().equals("*") || !queue.front().equals("/") || !queue.front().equals("%")
|| !queue.front().equals("+") || !queue.front().equals("-"))
{
stack.push(queue.removeFront()); // push the operand onto the stack
}
}
Here is the method that calls the processQueue() method
/*
Process the mathematical expression using a stack and a queue
*/
private static double processExpression() {
// insert all elements from the stack to the queue for processing
while(stack.top() != null) {
queue.insertBack(stack.pop());

I've placed the .mp3 file in the same directory as my project (where I've bin and src folders).
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).
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);

So, I decompiled a jar file and went to edit some code, but this is the only error i get upon decompiling which I am unable to find a fix for.
int i3 = var32.read(abyte0, k2, exception4);
if(i3 < 0) {
"Length error: " + k2 + "/" + j2; //Not a statement
throw new IOException("EOF");
}
I have a date sch_date_time=01/02/2014 08:00
And when i am doing SimpleDateFormat sdf = new SimpleDateFormat("dd/mm/yyyy HH:mm");
date1 = sdf.parse(sch_date_time);
when i am printing date1 it is printing as Wed Jan 01 08:00:00 IST 2014,but it should be printed as Sat Feb 01...

I've a .java file that won't compile, but produces no errors (in cmd prompt).
I think its the import of java.util.ArrayList thats causing the problem (because it can compile a different file in the same source folder) - so i'm assuming its the classpath that is wrong. which is fine. i love fighting with classpaths.
But why isn't it providing me with an error. the compiler usually goes bat-sh.. crazy if the -cp is incorrect!
Its because I'm switching between command prompt and a text editor and it hadn't saved the file for some reason, and still won't am getting rid of this editor!!
