Set is an interesting collection. It looks a bit like a list, but the actual operation is a bit like a map. Set is also a collection of records of a series of values, but it is the same as the map key, it cannot be duplicated, otherwise it will fail

In this article we will discuss various types of face questions in a Java interview that will allow employers to test the candidate's Java and common object-oriented programming capabilities. The following chapters are divided into two, the first

The collection framework is mainly divided into collection classes and mapping classes: The collection class stores a set of pure data, such as a set of objects. The mapping class stores a mapping of key-value pairs, but you can get the key

A set of objects that can be accessed by traversing each element (especially through the foreach loop)A collection contains multiple elements, that is, a collection class object and N element objects.Because any collection class implements the
