Explanation of the notes of the 'DS' framework in the Java class library

DS (Data Structure) framework is a module used to process data structures in the Java class library.Data structure is a very important concept in computer science. It is used to organize and store data in order to effectively operate and search.Java's DS framework provides a set of powerful classes and interfaces to achieve common data structures, such as array, linked lists, stacks, queues, trees, pictures, etc. In the Java library, the DS framework is widely used to solve various problems, from simple data management to complex algorithm implementation.It provides efficient data access and operation methods that can improve the performance and efficiency of the program.At the same time, the DS framework makes the code easier to read and maintain, and provides a wealth of notes to help developers better understand and use the data structure. Below several common data structures and corresponding Java code examples to explain the annotations of the DS framework in detail: 1. Array: Arrays are a linear data structure that consists of the same type of elements and accesses through indexes.The DS framework provides the ARRAY class, which can be used in the following notes: /** * Dynamic array class, used to store a set of elements */ public class Array<T> { // ... } 2. Linked List: The linked list is a data structure connected to the pointer. Each node contains data and reference to the next node.The DS framework provides the LinkedList class, which can be used as a detailed explanation: /** * One -way linked list, used to store a set of elements */ public class LinkedList<T> { // ... } 3. Stack: The stack is a data structure of the first -mounted (LIFO), which can only be inserted and deleted from the top.The DS framework provides the Stack class, which can be used in the following notes: /** * Stack category, used to realize the data storage and operation of the advanced advancement */ public class Stack<T> { // ... } 4. Queue: A queue is a advanced first -out (FIFO) data structure that can insert elements on one end and delete elements at the other end.The DS framework provides the Queue class, which can be used in details: /** * Quest class, used to achieve advanced data storage and operation */ public class Queue<T> { // ... } The above is just a detailed explanation of several common data structures in the DS framework.Java's DS framework also includes other data structures, such as trees, pictures, etc. Each class and interfaces have a corresponding explanation to help developers understand their usage and functions.By using the DS framework, developers can easily handle the data structure and improve the efficiency and maintenance of program.
