hierarchy . Collection represents a set of objects, also known as Collection elements . Some collection allow duplicate elements, while others do not. Some of the collection are orderly, while others are unordered. The JDK does not provide any direct implementation of this interface: it provides more specific sub-interfaces (such as Set and List) implementations. This interface is often used to pass collection and operate these collection where it is required to be the most universal.Collection

1. Using a stream to traverse a collectionBrief introduction:Java's collection framework, such as the list and map interfaces and the ArrayList and HashMap classes, makes it easy to manage both ordered and unordered collections. The collection framework has been continuously improved since the first day of introduction. In Java SE 8, we can manage, traverse, and aggregate collections through the flow's

() (similar to the keySet () method defined by the Map interface), these two methods are rarely used. Two differences: Hashtable is a thread-safe Map implementation, but HashMap is a thread-safe implementation, so HashMap has higher performance than Hashtable. However, if multiple threads access the same Map object, it is better to
