what should I use instead of double?

I created a simple currency converter app where the user enters the value in euro and the converted price is displayed in other currencies.
But how do I round up the numbers to the nearest 50 cent? so if 1 euro is equal to 1.3395 dollars how do I get the app to display 1.50 dollars?

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final EditText editEuro = (EditText) findViewById(R.id.editEuro); final EditText editAud = (EditText) findViewById(R.id.editAud); final EditText editCad = (EditText) findViewById(R.id.editCad); final EditText editNzd = (EditText) findViewById(R.id.editNzd); final EditText editGbp = (EditText) findViewById(R.id.editGbp); final EditText editUsd = (EditText) findViewById(R.id.editUsd); Button buttonConvert = (Button)findViewById(R.id.buttonConvert); buttonConvert.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { double euro = Double.valueOf( editEuro.getText().toString()); double aud = euro * 1.4471 ; double cad = euro * 1.4635 ; double nzd = euro * 1.5835 ; double gbp = euro * 0.7965 ; double usd = euro * 1.3395 ; editAud.setText(String.valueOf(aud)); editCad.setText(String.valueOf(cad)); editNzd.setText(String.valueOf(nzd)); editGbp.setText(String.valueOf(gbp)); editUsd.setText(String.valueOf(usd)); } });

Hi everyone, I am currently creating an Android game application as part of a college and I need to get some user feedback for a report. I would really appreciate to know what you think of the game.

If you could leave your comments on this post that would be great

I have an app that displays contents of an xml file that is stored on a server. The xml file contains a list of events and these events have categories. I want to be able to select which category I want then only display the events for that category. So I created a new xml with a spinner but I have no idea what I need to change in the code so for example if I select the film category only the film events are displayed. I know i will also need to change the events xml file.

here is some of the xml file:
<packages> <category> <name>City of Churches Exhibition</name> <date>March 20, 2014 - 19:00</date> <distance>0</distance> </category> <category> <name>Limerick Film Commission</name> <date>January 1, 2014 - 12:17</date> <distance>0</distance> </category> </packages>

and here is main java class that displays the xml file from the server:
public class TravelPackagesActivity extends Activity { /** Called when the activity is first created. */ static String LIST_URL = "http://server/packages.xml"; //xampp on mmserver ArrayList<HashMap<String, String>> packageList; Handler mHandler; PackageDownloadTask mTask; ProgressDialog mProgress; public Object onRetainNonConfigurationInstance() { Log.v("XML", "Saving data"); return packageList; } private void startBackgroundTask(){ mProgress = ProgressDialog.show(this, "Loading category packages", "Please wait...", true); mProgress.setCancelable(true); mProgress.setOnCancelListener(new OnCancelListener() { public void onCancel(DialogInterface arg0) { TravelPackagesActivity.this.finish(); } }); mProgress.show(); mTask = new PackageDownloadTask(); mTask.execute(); } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //loadTourPackages(); //displayTourPackages(); mHandler = new Handler() { public void handleMessage(Message msg){ mProgress.dismiss(); if (msg.what == 1) { new AlertDialog.Builder(TravelPackagesActivity.this) .setTitle("Error") .setPositiveButton(android.R.string.ok, null) .setMessage("Failed to download packages") .show(); } else { displayTourPackages(); } } }; packageList = (ArrayList<HashMap<String,String>>) getLastNonConfigurationInstance(); if (packageList == null) { startBackgroundTask(); } else { displayTourPackages(); } } private void displayTourPackages() { String from[] = { "name", "date", "distance" }; int to[] = { R.id.PackageTitle, R.id.PackageDate, R.id.PackageDistance }; SimpleAdapter a = new SimpleAdapter(this, packageList, R.layout.package_list_item, from, to); ListView l = (ListView) findViewById(R.id.PackageListView); l.setAdapter(a); } public class PackageDownloadTask extends AsyncTask<Void, Void, Void> { boolean bFailed = false; private void loadTourPackages() { try { HttpParams params = new BasicHttpParams(); HttpConnectionParams.setConnectionTimeout(params, 10000); HttpConnectionParams.setSoTimeout(params, 10000); DefaultHttpClient client = new DefaultHttpClient(params); HttpGet get = new HttpGet(LIST_URL); HttpResponse res = client.execute(get); int code = res.getStatusLine().getStatusCode(); if (code != 200) { throw new Exception("Invalid status code: " + code); } Log.v("XML", "Successfully fetched XML file"); InputStream is = res.getEntity().getContent(); packageList = new ArrayList<HashMap<String, String>>(); XmlPullParserFactory parserCreator = XmlPullParserFactory .newInstance(); XmlPullParser parser = parserCreator.newPullParser(); parser.setInput(is, null); int event; String name = null; String distance = null; String date= null; String tag = null; while ((event = parser.next()) != XmlPullParser.END_DOCUMENT) { if (isCancelled()) { Log.v("XML", "Cancelling XML processing"); break; } if (event == XmlPullParser.START_TAG) { tag = parser.getName(); if ("category".equals(tag)) { name = date= distance = ""; // Clear values } } else if (event == XmlPullParser.TEXT) { if ("distance".equals(tag)) { distance = parser.getText(); } else if ("name".equals(tag)) { name = parser.getText(); } else if ("date".equals(tag)) { date= parser.getText(); } } else if (event == XmlPullParser.END_TAG) { if ("category".equals(parser.getName())) { HashMap<String, String> map = new HashMap<String, String>(); map.put("name", name); map.put("date", date); map.put("distance", distance); packageList.add(map); Log.v("XML", "Loaded package: " + name); Thread.sleep(1000); } tag = null; // Reset tag name } } } catch (Exception e) { Log.v("XML", "Error fetching packages.xml", e); bFailed = true; } } @Override protected Void doInBackground(Void... params) { Log.v("XML", "Loading data from AsyncTask"); loadTourPackages(); if(!isCancelled()) { mHandler.sendEmptyMessage(bFailed ? 1 : 0); } return null; } } protected void OnDestroy() { if (mTask != null) mTask.cancel(false); super.onDestroy(); } }

In my android app I am trying to display the information of an xml file. I am using WAMP so I put the xml file in the www folder and set the url to static String LIST_URL = "http://10.0.2.2/www/packages.xml";
But when I try run the app on the emulator it just gets an error. What is the correct url for running xml files from WAMP?

I am not updating anything in the database. I just want to display the customer details from the order that was selected.
I know the problem isn't with the sql query because i tested that in the sql manager and it worked so problem is in jsf page

yes the query select * from customers works, i was able to display the customer information on a different page. so problem must be with jsf code

what is the difference between value and target? I have them set to the same thing. Could that be a problem?
<f:setPropertyActionListener value="#{customerBean.list}" target="#{customerBean.list}" />

I am using primeface in this project. I have a database with orders, order details and customers. The index page displays the order details and I click on one of the orders I want the customer details of that order to be displayed. But right now when I click on an order the dialog box that appears is empty. I'm not sure if the problem is with the jsf for the customer class.

here is the jsf page:
<p:dataTable value="#{orderDetailsBean.list}" var="anOrder" paginator="true" rows="10" paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}" rowsPerPageTemplate="5,10,15"> <f:facet name="header"> Classic Models </f:facet> <p:column sortBy="orderNumber" headerText="order Num"> <h:outputText value="#{anOrder.orderNumber}" /> </p:column> <p:column sortBy="orderDate" headerText="product code"> <h:outputText value="#{anOrder.productCode}" /> </p:column> <p:column sortBy="requiredDate" headerText="quantity ordered"> <h:outputText value="#{anOrder.quantityOrdered}" /> </p:column> <p:column sortBy="shippedDate" headerText="price"> <h:outputText value="#{anOrder.priceEach}" /> </p:column> <p:column style="width:4%"> <p:commandButton id="selectButton" update=":form:display" oncomplete="PF('orderDialog').show()" icon="ui-icon-search" title="View"> <f:setPropertyActionListener value="#{customerBean.customerList}" target="#{customerBean.customerList}" /> </p:commandButton> </p:column> </p:dataTable> <p:dialog header="Details" widgetVar="orderDialog" resizable="false" id="orderDlg" showEffect="fade" hideEffect="explode" modal="true"> <h:panelGrid id="display" columns="2" cellpadding="4" style="margin:0 auto;"> <h:outputText value="Customer's ID: " /> <h:outputText value="#{orderDialog.customerNumber}" style="font-weight:bold"/> <h:outputText value="Customer's Name: " /> <h:outputText value="#{orderDialog.customerName}" style="font-weight:bold"/> <h:outputText value="Credit Limit:" /> <h:outputText value="#{orderDialog.creditLimit}" style="font-weight:bold"/> </h:panelGrid> </p:dialog>

and the customer class:
public ArrayList getList() { cusomterList.clear(); try { ResultSet rs = stmt.executeQuery("Select * from customers"); if (!rs.next()) return null; else { rs.beforeFirst(); while (rs.next()) { Customers c = new Customers(rs.getInt("customerNumber"),rs.getString("customerName"),rs.getString("contactLastName"), rs.getString("contactFirstName"), rs.getString("phone"), rs.getString("addressLine1"),rs.getString("addressLine2"),rs.getString("city"), rs.getString("state"),rs.getString("postalCode"),rs.getString("country"),rs.getDouble("creditLimit")); cusomterList.add(c); } } } catch (SQLException ex) { System.out.println(ex); } return cusomterList; }

I created a game for android using Eclipse and I am trying to run the tests using JUnit. But I get an error every time I try run the tests and it creates a log file

here is error log file:

is something like this good unit testing?

public void testCoin() throws Exception { float x = 1.0f; float y = 1.0f; Coin result = new Coin(x, y); assertNotNull(result); } public void testUpdate() throws Exception { Coin fixture = new Coin(1.0f, 1.0f); fixture.stateTime = 1.0f; float deltaTime = 1.0f; fixture.update(deltaTime); }

thanks. could you show me the code for how to do that?

I'm creating an Android game using Eclipse and I want to do some unit testing using JUnit.
I know how to create the tests and JUnit automatically creates methods in the test but I am not sure what would go into those methods.

For example I have a coin class in the project:
public class Coin extends GameObject { public static final float COIN_WIDTH = 0.5f; public static final float COIN_HEIGHT = 0.8f; public static final int COIN_SCORE = 10; float stateTime; public Coin (float x, float y) { super(x, y, COIN_WIDTH, COIN_HEIGHT); stateTime = 0; } public void update (float deltaTime) { stateTime += deltaTime; } }

And JUnit makes this file:
public class CoinTest extends TestCase { public void testCoin() { fail("Not yet implemented"); } public void testUpdate() { fail("Not yet implemented"); } }

What should I put in the test case methods to test the coin?

Personally, I've found storing state to shared preferences preferable

ok how would I do that?

What should be used to save the values during orientation change?
