get in set java code example

Example 1: java get set

class Employ
{
  public String name;						//name of the employ
  
  public String getName()					//Get the name
  {
    return name;
  }
  
  public String setName(String newName)		//Set the name
  {
    this.name = newName;
  }
}

Example 2: set in java

SET: Can only store unique values, 
     And does not maintain order
- HashSet can have null, order is not guaranteed
- LinkedHashSet can have null and keeps the order 
- TreeSet sorts the order and don't accept null

Example 3: 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) {}
   }
}
