        d.get("http://seleniumhq.github.io/selenium/docs/api/java/index.html");
        assertEquals("Overview",d.getTitle());
        List<WebElement> f=d.findElements(By.tagName("frame"));

Remove duplicates from Array in java

package java_interview;

import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;
import java.util.TreeSet;

public class Duplicate_String_Remover_Without_String
{
    static int[]  arr={1,2,3,1,4,5,3};
   
public static void main(String[] args) {
   
    //Way 1 pass
    /*TreeSet<String> set=new TreeSet<String>();
    set.add("pabbu");
    set.add("reddy");
    set.add("java_practice");
    set.add("reddy");
    set.add("aaa");
    System.out.println("printing all values from tree set: " + set);
    Iterator<String> itr=set.iterator();
        while(itr.hasNext())
        {
        System.out.println("printin tree values after iterating: " + itr.next());       
   
        }
*/
   
    //Way 2 pass   
   
        int end = arr.length;
        Set<Integer> set = new HashSet<Integer>();
        for (int i = 0; i < end; i++) {
            set.add(arr[i]);
        }
        Iterator it = set.iterator();

Write code for Palindrome and reverce string. e.g madam, dad

Way 1: Using For loop  :

package java_interview;

public class Polindrom_Using_ForLoop {
    static String original="abac";
  
    public static void main(String[] args) {
      
  
        String reverse="";
        int length = original.length();
        
          for ( int i = length - 1 ; i >= 0 ; i-- )
             reverse = reverse + original.charAt(i);
    
          if (original.equals(reverse))
             System.out.println(original+" is a palindrome.");
          else
             System.out.println(original+" is not a palindrome.");
    }
}

Way2 : Using String Builder:

package java_interview;

public class Polindrom_Test {
static String txt="madam";
public static void main(String[] args)
{
//Using string builder
String strbuilderTxt=new StringBuilder(txt).reverse().toString();
System.out.println("Printing string using string builder class : " + strbuilderTxt);
if(txt.equals(strbuilderTxt))
{
    System.out.println("Ploindrome :");
}
else {
    System.out.println("Not a Ploindrome :");
}
}
}
 

Selenium Grid

 Selenium-Grid allows you run your tests on different machines against different browsers in parallel.

Start hub: java -jar selenium-server-standalone-2.38.0.jar -role hub

Start node: java -jar selenium-server-standalone-2.38.0.jar -role node  -hub http://localhost:4444/grid/register

Create RemoteWebDriver object

WebDriver driver = new RemoteWebDriver(hub-url,capabilities);

Difference between JUnit&TestNG?

Selenium code for 'google search' auto suggestions and print result?

public class Auto_Suggestions {

 @BeforeTest  

 public void start(){  

   driver = new FirefoxDriver();   

 }  

    

 @Test  

  public void SearchSuggestion() {  

    

  driver.get("http://google.com");  

  driver.findElement(By.id("gbqfq")).sendKeys("v2tech");  

  driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);  

    

   WebElement table = driver.findElement(By.className("gssb_m"));   

   List<WebElement> rows = table.findElements(By.tagName("tr"));   

   Iterator<WebElement> i = rows.iterator();   

   System.out.println("-----google auto suggestions are:---------");   

   while(i.hasNext()) {   

           WebElement row = i.next();   

           List<WebElement> columns = row.findElements(By.tagName("td"));   

           Iterator<WebElement> j = columns.iterator();   

           while(j.hasNext()) {   

                   WebElement column = j.next();   

                   System.out.println(column.getText());   

           }   

           System.out.println("");   

              

   System.out.println("google auto suggestions are:");   

   }   

  }
