Java Set is an interface that implements the Collection interface. It represents a collection of elements without any duplicates. The Set interface provides several methods to perform various operations on the elements of the set.
Code Example 1:
Set set = new HashSet<>(); set.add("Apple"); set.add("Banana"); set.add("Orange"); System.out.println(set.toString());
This code creates a HashSet of Strings, adds three elements, and then prints the entire set as a String using the toString() method.
Package Library: java.util
Code Example 2:
Set set = new TreeSet<>(); set.add(10); set.add(5); set.add(20); System.out.println(set.toString());
This code creates a TreeSet of Integers, adds three elements, and then prints the entire set as a String using the toString() method. The TreeSet automatically sorts the elements, so the output will be [5, 10, 20].
