Solong Collections Framework: Data structure and algorithm in the Java class library
Solong Collections Framework: Data structure and algorithm in the Java class library
Overview:
Solong Collections framework is a powerful class library in the Java language, which provides rich data structures and algorithms that enable programmers to process and operate various data more conveniently.This article will introduce some of the core features and common functions of the Solong Collections framework, and provide some Java code examples to help readers understand and apply these functions.
1. Data structure:
Solong Collections framework contains a variety of commonly used data structures, including:
-ArrayList: You can dynamically adjust the array of size, provide efficient random access and modification operations.
-LinkedList: The data structure composed of nodes provides efficient order access and inserting and deleting operations.
-HashMap: The key values implemented based on hash functions are based on the storage structure, providing efficient insertion, deleting and finding operations.
-Tree: Including binary trees and balance trees, providing efficient orderly search and inserting and deleting operations.
-In graph (Graph): The data structure composed of nodes and edges is used to solve the problem -related problems.
Below is an example code that uses ArrayList and Hashmap in the Solong Collections framework:
import com.solong.collections.ArrayList;
import com.solong.collections.HashMap;
public class DataStructureExample {
public static void main(String[] args) {
// Use ArrayList
ArrayList<String> list = new ArrayList<>();
list.add("Apple");
list.add("Banana");
list.add("Orange");
System.out.println("ArrayList: " + list.toString());
// Use HashMap
HashMap<Integer, String> map = new HashMap<>();
map.put(1, "John");
map.put(2, "Jane");
map.put(3, "Mike");
System.out.println("HashMap: " + map.toString());
}
}
2. Algorithm:
Solong Collections framework also provides a variety of common algorithms, including sorting, searching, graph algorithms, etc.Here are some examples of common algorithms:
-Sorting Algorithms:
import com.solong.collections.Arrays;
public class SortingExample {
public static void main(String[] args) {
int[] arr = {5, 2, 8, 3, 1};
Arrays.sort(arr);
System.out.println("Sorted Array: " + Arrays.toString(arr));
}
}
-Searching Algorithms:
import com.solong.collections.Arrays;
public class SearchingExample {
public static void main(String[] args) {
int[] arr = {5, 2, 8, 3, 1};
int target = 8;
int index = Arrays.binarySearch(arr, target);
System.out.println("Target found at index: " + index);
}
}
-Graph algorithms::
import com.solong.collections.Graph;
public class GraphExample {
public static void main(String[] args) {
Graph graph = new Graph(5);
graph.addEdge(0, 1);
graph.addEdge(1, 2);
graph.addEdge(2, 3);
graph.addEdge(3, 4);
System.out.println("Graph: " + graph.toString());
}
}
in conclusion:
Solong Collections framework is a powerful and easy -to -use data structure and algorithm library in the Java class library, providing programmers with rich functions and convenient operations.This article introduces some of the core features and common functions of the framework, and provides some Java code examples to help readers understand and apply the framework.It is hoped that readers can make full use of the Solong Collections framework to optimize their Java program development through learning and practice.
