How To Get An Element From Object In Java. We can retrieve the first element in a set using an iterator. The three different ways we can get elements by index in a hashset is by: In order to add an element to the set, we can use the add () method. Since no get method exists on set, the best we can do is either use an iterator and find the first element that matches based on equals, or to use the stream api. Declare the hashset using set interface; Import the required java package java.util; The set interface allows us to get an iterator for all implementations using. Results){ string name = ((testproject)tp).getname() ; In that way, you can efficiently retrieve an element from the set, because the get () method of the map will find the element. However, the insertion order is not retained in the set. Display the hashset to determine order of elements The get() method of arraylist in java is used to get the element of a specified index within the list. Add elements into the hashset using the add() method; Internally, for every element, a hash is generated.
