Collections and DBConnections and Grid

HashMap:
public class CollectionsHashMap {

public static void main(String[] args) {
// TODO Auto-generated method stub
HashMap hs = new HashMap();
HashMap hsNew = new HashMap();

// practise purpose

HashSet:

public class CollectionsHashSet {

// TODO Auto-generated method stub

HashSet obj = new HashSet();
obj.add(10);
obj.add(20);
obj.add(30);

//which contains same features what we have in ArrayList but it dont have the obj.get(indexval)

HashSet hss = new HashSet();
hss.add("Santosh");

Iterator it = hss.iterator();
while(it.hasNext()){
System.out.println(it.next());

}

LinkedList:

public class CollectionsLinkedList {

public static void main(String[] args) {

// TODO Auto-generated method stub

LinkedList al=new LinkedList();  

  al.add("Ravi");  

  al.add("Vijay");  

  al.add("Ravi");

  }

  System.out.println("Before remove: " + al.get(2));

  al.remove(2);

  System.out.println("After remove: " + al.get(2));

  

  // while(itr.hasNext()){  

  // System.out.println(itr.next());  

  //}  

}

}

DBConnection:

public class DBConnection {

public static void main(String[] args) throws SQLException, ClassNotFoundException {

// TODO Auto-generated method stub

Class.forName("oracle.jdbc.driver.OracleDriver");  

String host = "md1npdlnxdb08";

ResultSet res = stm.executeQuery("select * from md_column_info where schema_name = 'WWF_2016_19_18PROP' and table_name='DN_TARGET' and column_name = 'OWNER'");

res.next(); 

}

}

GRID:

public class GridEx {

@Test

void grid() throws MalformedURLException{

DesiredCapabilities dc = new DesiredCapabilities().chrome();

dc.setBrowserName("chrome");

//dc.setCapability("marionatte", false);

//ChromeOptions opt = new ChromeOptions();

System.out.println(1);

//System.setProperty("webdriver.chrome.driver", "C:\\Automation\\Selenium\\drivers\\chromedriver_win32\\chromedriver.exe");

System.out.println(2);

}

private DesiredCapabilities DesiredCapabilities() {
