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");

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

public class Auto_Suggestions {

 }  

    

 @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"));

           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:");
