Set is an interface which extends Collection. It is an unordered collection of objects in which duplicate values cannot be stored. Basically, Set is implemented by HashSet, LinkedHashSet or TreeSet (sorted representation).Click to see full answer. Herein, what is get () in Java?get() is an inbuilt method in Java and is used to return the element at a given index from the specified Array. Parameters : This method accepts two mandatory parameters: array: The object array whose index is to be returned. The element at ‘index’ in the given array is returned.Similarly, what is the use of getter and setter in Java? In Java, getter and setter are two conventional methods that are used for retrieving and updating the value of a variable. So, a setter is a method that updates the value of a variable. And a getter is a method that reads the value of a variable. Getter and setter are also known as accessor and mutator in Java. Similarly one may ask, how does a set work in Java? HashSet implementation internally in Java. Set achieves the uniqueness in its elements through HashMap . When an element is passed to Set , it is added as a key in the HashMap in the add(Element e) method. Now, a value needs to be associated to the key.How is a method defined in Java?A method is a set of code which is referred to by name and can be called (invoked) at any point in a program simply by utilizing the method’s name. Think of a method as a subprogram that acts on data and often returns a value. Each method has its own name.
