iterate through hash_set code example

Example 1: iterating over hash, ruby

# iterating_over_hashes.rb

person = {name: 'bob', height: '6 ft', weight: '160 lbs', hair: 'brown'}

person.each do |key, value|

end


#Returns

#Bob's height is 6 ft
#Bob's weight is 160 lbs

Example 2: hashset in java

Let’s see java hashset example.

import java.util.HashSet;
public class HashSetExample
{
   public static void main(String[] args)
   {
      HashSet<String> hs = new HashSet<>();
      hs.add("Banana");
      hs.add("Orange");
      hs.add("Apple");
      hs.add("Pineapple");
      hs.add("Mango");
      System.out.println(hs);
   }
}
