I'm trying to pull the authors from this Json object but I'm having issues trying to pull the author only, I'm only able to get a huge string which is a valid JSON object i tested it in [URL]
private class RunSearch extends AsyncTask<String, Void, String> {
private Exception e;
protected String doInBackground(String ...query){

I am trying to learn how to parse a Json with java. So I have this code
import java.net.*;
import java.io.*;
public class test2 {
public static void main(String[] args) throws Exception {
[Code] .....
and it has this output
{
"response": {
"version":"0.1",
"termsofService":"http://www.wunderground.com/weather/api/d/terms.html",
"features": {
"conditions": 1
[code]...
How do I turn this information into java objects?
I have written my program result into a json file but i am getting json file in below format.
{"one":"one","two":"two","three":"three"}
but I have lot of entries to write into json finally it become unreadle format which is not very compart to read.
Is there any way to format or writing line by line into json file like below format,
{
"one":"one",
"two":"two",
"three":"three"
}
I'm working on a method that would parse the value of the array of object that I passed through a parameter. I would like to ask if making Object as a parameter is doable. Let's say I have a class Student and Teacher. I created a class the would handle the sched and name it class Schedule and extend this class to the Student and Teacher. Now I want to have a function that will accept an array of Schedule from either Student and Teacher, what ever object I will pass in the parameter. I know its easy to just make a method with a separate parameter of my classes but im looking for a more dynamic code.
class Student extends Schedule{
//variables here for student
}
[code]
class Teacher extends Schedule{
//variables here for teacher
}
[/code]
private void parseObject(ArrayList<Object> objct){
Schedule temp = objct.get(0);
//there is no error in this part
}
Now when i will try to use the function and pass a data, it will not accept since my parameter should be an array of object. How would I twist dis one?
ArrayList<Student> temp_student = new Array....
parseObject(temp_student); // it will not accept my parameter, how would i make it as an object
Please find below my JSON object ,how can we split
[
{"alpha2Code":"AF",
"alpha3Code":"AFG",
"altSpellings":"AF,Afganistan",
"area":652230.0,
"callingcode":"93",
"capital":"Kabul",

"gini":27.8,

I need it should be split & Write Java code by JSONArray and JSONObject

I want the result to be sth like this:
1992 1,2,3,4
1992 5,67

and a table of mappings
M_DINE 1
R_LEIGH 2
P_HUET 3

I give my dataset in csv (or text) format to my program but it says "(The system cannot find the file specified)" even though the file exists.
what should I do?
here is my code:

Barbara is opening a book store, and she needs an effective, efficient, object-oriented program to keep track of her inventory. Barbara would like to maintain the following information about the books she sells: title, author, price, number in stock, and category. She categorizes her books into fiction, nonfiction and children’s books, because she has a separate room in her store for each category. Each book also needs an inventory number, and Barbara would like these numbers to start with 1000. She also needs to be able to keep track of the total number of books in inventory.
Barbara often facilitate her customers find books, and the program needs search capabilities to do this. Keeping an accurate inventory count of each book in stock is critical; both for accounting purposes and so she will know when to reorder. Barbara expects to have at most 2,000 differet books in her store.Barbara is very organized, and would like a nice menu, from which she can make choices that will enable her to do the following:
Add a new book to inventory
This adds a new Book object (title, author, etc) into inventory
It does not increase the number in stock of an existing book
Search by title
Search by author
Search by inventory number
Search by category
Print out all info for all books
This is the only output that should be on the command line
Please hard code the following book info into your program, so Barbara has some test data avaiable to test your program:
title: Crime and Punishment; author: Dostoevsky; price: 39.95; number in stock: 5; category: fiction
title: Brothers Karamazov; author: Dostoevsky; price 34.50; number in stock: 3; category: fiction
title: Java; author: Liang; price: 59.29; number in stock: 12; category: non-fiction
title: Java, author: Horstmann; price: 14.33; number in stock: 4; category: non-fiction
title: The Lion, the Witch and the Wardrobe; author: Lewis; price: 12.50; number in stock: 3; category: childrens
Here is my code so far. The first one is the "Blueprint" and the second one is the main.
public class Book
{
private String title;
private String author;
private double price;
private int stockNumber;
private String category;
private int inventoryNumber =1000;
private static int numberOfBooks = 0;
public Book(String theTitle, String theAuthor, double thePrice, int theStockNumber, String theCategory)

I'm quite new in android programming and I've meet some problem in push and pull method. I have created 2 activity in my app 1 of them call Push_activity and Pull activity(Code are shown below). The String that I keyed in PushActivity have to "transfer" to the PullActivity when the button is pressed:
PullActivity
but1 = (Button)findViewById(R.id.buttonll);
tx = (TextView)findViewById(R.id.editText1);
tx.setText(getIntent().getStringExtra("extra"));
but1.setonclickListener(new onclickListener(){
[Code] ....
The app works fine when it started. When I press the button in PushActivity, it crashed and the error came from my textview in PullActivity.
I'm unable to get the output for "AverageDriver" to print correctly(5 scores in descending order and average). The output displays the scores the same way they are entered and the average is always zero. The output for the Average program works fine and with the correct output.
import java.util.Scanner;
//This class keeps 5 scores entered by the user
public class Average

private int[] data;
private double mean;

This program reads off of a text file that I have attached to my post. It is supposed to:
display the total sales for each week
the average daily sales for each week
the total sales for all of the weeks
the average weekly sales
the week number that had the highest amount of sales
the week number that had the lowest amount of sales
I can get everything but the very last one. In my code you will see that I tried to use a really large number so it would pull out the lowest amount, but it still didn't work: low = 100000000;

I've been trying to pull data from another class file "Calculations.java" and have it be displayed in a TextField in "DataAnalyzerGUI.java". Here is how the hierarchy is broken down for my assignment:
DataAnalyzerGUI.java extends JFrame
ReadFiles.java extends DataAnalyzerGUI.java
Calculations.java extends ReadFiles.java
Everything displays and functions correctly in a command prompt if I use a line like this:
System.out.println ("Lowest opening " + dateArray[lowestOpenIndex] + ": " + dataArray[lowestOpenIndex][2]);
But trying to get it to display in a GUI has been quite troubling.
I know the code is supposed to look something like this:
dataOutput.setText(DESIRED CODE HERE);
But I am unable to find anything of value to work out.
I have attached my complete project....

I'm learning about inheritance and on this problem I first have to create a class where I get/set methods and get user input for the data fields.
I suppose I should know it at this point but I don't know how to get the users name when they input it. I copied the whole code but the issue is at line 51.

I have date in string ex: 2014-08-08T17:38:58.316+05:30 and want to convert into 2014/08/08 17:38:58. I am using below code :
String date1="2014-08-08T17:38:58.316+05:30";
SimpleDateFormat formatter, FORMATTER;
formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
String oldDate = "2011-03-10T11:54:30.207Z";
Date date = formatter.parse(oldDate.substring(0, 24));
FORMATTER = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss.SSS");
System.out.println("OldDate-->"+oldDate);
System.out.println("NewDate-->"+FORMATTER.format(date));
this giving me required value, but when i replace oldDate with date1 it shows me exception that not parse to date. Actually i am getting date in string of 2014-08-08T17:38:58.316+05:30 which i need to convert into date 2014/08/08 17:38:58. To convert into date i am using below code :
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/M/yyyy hh:mm:ss");
Date datecomp1 = simpleDateFormat.parse(String );
The issue is to convert 2014-08-08T17:38:58.316+05:30 into 2014/08/08 17:38:58.
