Why does the mean method does not work correctly?

I have the following class imp with inner class ScoringSummaryImplementation, when I tested the mean() method alone it works correctly, but when I test it as I show in the main method the answer goes incorrectly, I need to know the reason:
public class imp implements Normalizer {
public static List<BigDecimal> dataToBeNormalized = new ArrayList<>();
#Override
public ScoringSummary zscore(Path csvPath, Path destPath, String colToStandardize) {
ScoringSummary scoringObejct = new ScoringSummaryImplementation();
if (!Files.exists(csvPath)) {
throw new IllegalArgumentException("source file not found");
}
try {
readDataToBeNormalized(csvPath, destPath, colToStandardize);
} catch (IOException ex) {
Logger.getLogger(imp.class.getName()).log(Level.SEVERE, null, ex);
} catch (CsvValidationException ex) {
Logger.getLogger(imp.class.getName()).log(Level.SEVERE, null, ex);
}
//Z-score
for (int i = 0; i < dataToBeNormalized.size(); i++) {
BigDecimal sub = (dataToBeNormalized.get(i).subtract(scoringObejct.mean()));
try {
BigDecimal divide = sub.divide(scoringObejct.standardDeviation(), 2, RoundingMode.HALF_EVEN);
dataToBeNormalized.set(i, divide);
} catch (ArithmeticException e) {
}
}
return scoringObejct;
}
private void readDataToBeNormalized(Path csvPath, Path destPath, String colToStandardize) throws FileNotFoundException, IOException, CsvValidationException {
int indexOfTheCol = -1;
CSVReader reader = new CSVReader(new FileReader(csvPath.toString()));
String[] header = reader.readNext();
for (int i = 0; i < header.length; i++) {
if (header[i].equalsIgnoreCase(colToStandardize)) {
indexOfTheCol = i;
}
}
if (indexOfTheCol == -1) {
throw new IllegalArgumentException("column " + colToStandardize + " not found");
}
String[] values;
while ((values = reader.readNext()) != null) {
dataToBeNormalized.add(new BigDecimal(values[indexOfTheCol]));
}
}
//Inner class to implement ScoringSummary
public static class ScoringSummaryImplementation implements ScoringSummary {
#Override
public BigDecimal mean() {
BigDecimal sum = new BigDecimal("0");
BigDecimal sizeOfTheList = new BigDecimal(dataToBeNormalized.size());
for (int i = 0; i < dataToBeNormalized.size(); i++) {
sum = sum.add(dataToBeNormalized.get(i));
}
sum.divide(sizeOfTheList, 2, RoundingMode.HALF_EVEN);
return sum.divide(sizeOfTheList, 2, RoundingMode.HALF_EVEN);
}
}
}
// test in the main:
public class Test {
public static void main(String [] args){
Path p = Paths.get("C:\\Users\\DELL\\Documents\\GitHub\\J2EE\\demo\\src\\main\\java\\com\\mycompany\\demo\\d.csv");
Path p2 = Paths.get("C:\\Users\\DELL\\Documents\\GitHub\\J2EE\\demo\\src\\main\\java\\com\\mycompany\\demo\\des.csv");
Normalizer n1 = new imp ();
ScoringSummary n2 = n1.zscore(p, p2, "age");
BigDecimal mean = n2.mean();
System.out.println(mean);
}
}
Here is output:
0.82
Here is age column:
|age |
|5434|
|42423|
|54534|
|3333|

Could not render red5 recorded media stream

How to locate or work with different locator in selemium webdrier frameowrk?

I am beginner in selenium webdriver, I am trying to work with different locator by reading excel sheet but in these it take only one data put it in one field by finding locator "id", and when it come to the second text field for this we are using locator by "Xpath" but its not taking. So, my question is how can I work with different locator also by don't using switch case if possible.
Below are my code:
public class MainClass {
private static final String BROWSER_PATH = "D:\\firefox.exe";
private static final String TEST_SUITE_PATH = "D:\\GmailTestSuite.xls";
private static final String OBJECT_REPOSITORY_PATH = "D:\\objectrepository.xls";
private static final String ADDRESS_TO_TEST = "https://www.gmail.com";
// other constants
private WebDriver driver;
private Properties properties;
/*private WebElement we;*/
public MainClass() {
File file = new File(BROWSER_PATH);
FirefoxBinary fb = new FirefoxBinary(file);
driver = new FirefoxDriver(fb, new FirefoxProfile());
driver.get(ADDRESS_TO_TEST);
}
public static void main(String[] args) throws IOException, BiffException {
MainClass main = new MainClass();

}
private void handleTestSuite() throws BiffException, IOException {

System.out.println("Total Rows=" + rowCount);
for (int i = 1; i < rowCount; i++) {
String executable = testSuite.readCell(testSuite.getCell("Executable"), i);
System.out.println("Executable=" + executable);
if (executable.equalsIgnoreCase("y")) {
// exe. the process
String scenarioName = testSuite.readCell(testSuite.getCell("TestScenario"), i);
System.out.println("Scenario Name=" + scenarioName);
handleScenario(scenarioName);
}
}
}
private void handleScenario(String scenarioName) throws BiffException, IOException {
ExcelHandler testScenarios = new ExcelHandler(TEST_SUITE_PATH);
testScenarios.setSheetName("Login");
testScenarios.columnData();
int rowWorkBook1 = testScenarios.rowCount();
for (int j = 1; j < rowWorkBook1; j++) {

You need the Reflection. See example in 2 methods below:
import java.lang.reflect.Method;
...
#Test
public void TestAmazon() {
driver = new ChromeDriver();
driver.navigate().to("http://www.amazon.com");
String locatorType = "id";
String locatorExpression = "twotabsearchtextbox";
By locator = createLocator(locatorType, locatorExpression);
WebElement textbox = driver.findElement(locator);
textbox.sendKeys("Star Wars: The Digital Movie Collection");
textbox.sendKeys(Keys.ENTER);
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
locatorType = "className";
locatorExpression = "nav-logo-link";
locator = createLocator(locatorType, locatorExpression);
driver.findElement(locator).click();
}
private By createLocator(String locatorType, final String locatorExpression) {
By locator = null;
Class<By> byClass = By.class;
Class[] argTypes = new Class[] { String.class };
try {
Method m = byClass.getDeclaredMethod(locatorType, argTypes);
try {
locator = (By)m.invoke(null,locatorExpression);
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return locator;
}

Java: Android: SQLite: Doing Multiple Inserts Using a For Loop

Please review the following piece of code:
try {
db.beginTransaction();
db.execSQL(DBConstants.PRAG_FOR_KEYS_ON);
db.execSQL(DBConstants._BLDG_CREATE);
db.execSQL(DBConstants._BLDG_INDEX);
for(int x = 0; x < 28; x = x+1){
db.execSQL(DBConstants._BLDG_INSERT+x);
}
db.execSQL(DBConstants.PRAG_FOR_KEYS_OFF);
db.setTransactionSuccessful();
} catch (SQLException e) {
e.printStackTrace();
}finally{
db.endTransaction();
}
Each of the insert constants (representing a row of new data) are numbered thus:
public static final String _BLDG_INSERT0 = "<SQL insert statement>"
...all the way up to 28 ("_BLDG_INSERT28").
Is there ANY way i can execute these SQL statements in a for loop? If i can, how do i concactenate the number on to the name of the constant AND have it recognized by the java interpreter in the correct way?
Thanks!

It's not clear from the question whether you are able to change the constants. If you can, it would be better if you could put the statements in an array.
String[] _BLDG_INSERT = {"<SQL insert statement>", // 0
"<SQL insert statement>", // 1
...
"<SQL insert statement>" // 28
};
And then you can just access them like this.
for(int x = 0; x < 28; x = x+1){
db.execSQL(DBConstants._BLDG_INSERT[x]);
}
Or better still:
for(String s : DBConstants._BLDG_INSERT) {
db.execSQL(s);
}

public ArrayList<String> getAllRecord()
{
ArrayList<String> total = new ArrayList<String>();
Cursor cursor1 = null;
try
{
cursor1 = getDBobject().rawQuery(
"select * from "
+ Your table name + ";", null);
if (cursor1.moveToFirst())
{
do
{
String cid = cursor1.getString(1);
total.add(cid);
}
while (cursor1.moveToNext());
}
}
catch (Exception e)
{
System.out.println("" + TAG + " :" + e);
}
finally
{
if (cursor1 != null && !cursor1.isClosed())
{
cursor1.close();
}
}
return total;
}
This will return you all the datas according to your insertion order

Try something like this:
public class testeReflection {
public static void main(String[] args) throws IllegalArgumentException, IllegalAccessException{
MyClass myClass = new MyClass();
Class aClass = MyClass.class;
for(int i = 0; i < 5; i++){
try {
Field field = aClass.getField("VAR" + i);
String s = (String)field.get(myClass);
System.out.println("myClass[" + i + "] = " + s);
} catch (NoSuchFieldException ex) {
Logger.getLogger(testeReflection.class.getName()).log(Level.SEVERE, null, ex);
} catch (SecurityException ex) {
Logger.getLogger(testeReflection.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
public static class MyClass{
public static final String VAR0 = "VARIAVEL 01";
public static final String VAR1 = "VARIAVEL 02";
public static final String VAR2 = "VARIAVEL 03";
public static final String VAR3 = "VARIAVEL 04";
public static final String VAR4 = "VARIAVEL 05";
}
}

Java and Hyper-V

I am trying to learn something about JAVA and the best way to do this is creating something I would actually use and know what the purpose of it is.
I am trying to communicate with HyperV (WMI Library).
For example I found the following, my question is: how to use it? I am using Netbeans to create the GUI.
http://www.paulneve.com/wlab/javadoc/org/paulneve/wlab/virtualisation/VirtualisationAccessHyperVImpl.html
Also, how to load jInterop into my project so I can use it?
Thank you.

You can use JInterop for managing all operations of HyperV.
Download JInterop from here.
Add all JInterop jar files to your project build path.
Following is an example of getting all VMs of Hyper server:
