how to get elements from set code example

Example 1: set get javascript

var person = {
  language : "en",
  get lang() { return this.language; },
  set lang(lang) { this.language = lang; }
};
document.getElementById("demo").innerHTML = person.lang;
person.lang = "es";

Example 2: java set example

import java.util.*;
public class SetDemo {

  public static void main(String args[]) { 
      int count[] = {34, 22,10,60,30,22};
      Set<Integer> set = new HashSet<Integer>();
      try {
         for(int i = 0; i < 5; i++) {
            set.add(count[i]);
         }
         System.out.println(set);

         TreeSet sortedSet = new TreeSet<Integer>(set);
         System.out.println("The sorted list is:");
         System.out.println(sortedSet);

         System.out.println("The First element of the set is: "+ (Integer)sortedSet.first());
         System.out.println("The last element of the set is: "+ (Integer)sortedSet.last());
      }
      catch(Exception e) {}
   }
}

Example 3: get set

class Thing {
  private int secret; // This is a field.

  public int Secret { // This is a property.
    get {
      Debug.Print("Somebody is accessing the secret!");
      return secret;
    }

    set {
      Debug.Print("Somebody is writing to the secret!");
      secret = value; // Note the use of the implicit variable "value" here.
    }
  }
}
