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.

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.

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.

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"

I am trying to write a simple program that checks if a user's input has a specific letter using the ".contains" method but its not doing what i wanted to do. here is my code below.

Scanner sc;
char hidden='a';
String guess;
[Code] ....
So I have to design a program that takes a word and reverses the order of it. The exact directions are:Write a recursive method void reverse() that reverses a sentence. For example:
[code = Java]
Sentence greeting = new Sentence("Hello!");
greeting.reverse();
System.out.println(greeting.getText());
[/code]
prints the string "!olleH".
Implement a recursive solution by removing the first character, reversing a sentence consisting of the remaining text, and combining the two. So basically my biggest issue is my method to actually reverse the word.
public class Sentance
{
private String Word;
public Sentance (String aWord)
{
Word = aWord;
[code]....
I am not very comfortable with Strings in Java. The problem I am facing is, taking a string that contains a sentence and reversing the words. Example would be, "Hi I am Bob" and changing it to "Bob am I Hi". Then returning the String.
My initial thoughts were to change the string into a character array and then manually doing the work with loops and tedious comparison statements. I quickly realized that there must be a better way but I am not very familiar with strings in Java to know what a more sufficient way would be.
i am new to programming skills it may be silly question for experience but for me it's new thing. actually i tried a lot but i am facing problem when i trying to take input through Scanner. if i will take input a sentence directly as a string it's working . but when i am trying with Scanner the first word is showing next are not showing
public class Demo2
{
public static void main(String[] args)
{
String s1="hi how are you";
s1=s1.replace('a', 'A');
s1 =s1.replace('e', 'E');
s1 =s1.replace('i', 'I');
[Code]...
this is working properly.
but when i trying with Scanner i am facing problem.
public class Demo2
{
public static void main(String[] args)
{
java.util.Scanner scn= new java.util.Scanner(System.in)
String s1=scn.next();
s1=s1.replace('a', 'A');

Write a program to reverse each word in line(sentence)?
View Replies View RelatedOk, so I have to make a program that tells the user to type a sentence and at the end of the sentence a "." must be put to end the program. If a "." period is not entered, it must re-prompt the user to enter a period. On top of all this, the program has to count the number of letters in the sentence. I cant seem to get the while loop working and I cant find anywhere how to make a counter count the number of letters.

The purpose of this program is to translate a user inputed sentence into morseCode. It seems like everything is right to me, but I'm simply not getting output! What am I doing wrong, or what should I add/change?
