Learn about the technical principles of the FS Extra framework in the Java library
The FS EXTRA framework is a powerful tool in the Java class library, which provides the function of convenient and simplified the operation of the file system.This article will introduce the technical principles of the FS Extra framework and explain its use through the Java code example.
The FS EXTRA framework is an extension based on the standard file system API of Java.It provides a set of high -end functions that make the creation, replication, movement, deletion, etc. of files and folders more simple and flexible.In addition, FS Extra also provides some additional functions, such as recursively traversing folders, checking whether files exist, and obtaining file size.
The core idea of the FS EXTRA framework is to provide a simpler way to handle file system operations.It introduces some categories and methods to make these operations more intuitive and easy to use.Here are some commonly used technical principles and examples of the FS EXTRA framework:
1. Create a folder:
import nl.takke.filesystem.FS;
import nl.takke.filesystem.Folder;
FS fs = new FS();
Folder folder = fs.createFolder("/path/to/folder");
2. Copy file:
import nl.takke.filesystem.FS;
import nl.takke.filesystem.File;
FS fs = new FS();
File sourceFile = fs.createFile("/path/to/source/file");
File targetFile = fs.createFile("/path/to/target/file");
fs.copyFile(sourceFile, targetFile);
3. Mobile folder:
import nl.takke.filesystem.FS;
import nl.takke.filesystem.Folder;
FS fs = new FS();
Folder sourceFolder = fs.createFolder("/path/to/source/folder");
Folder targetFolder = fs.createFolder("/path/to/target/folder");
fs.moveFolder(sourceFolder, targetFolder);
4. Delete files:
import nl.takke.filesystem.FS;
import nl.takke.filesystem.File;
FS fs = new FS();
File file = fs.createFile("/path/to/file");
fs.deleteFile(file);
5. Traversing folders:
import nl.takke.filesystem.FS;
import nl.takke.filesystem.Folder;
FS fs = new FS();
Folder folder = fs.createFolder("/path/to/folder");
for (File file : fs.listFiles(folder)) {
System.out.println(file.getName());
}
Through these examples, we can see that the FS Extra framework simplifies the complexity of the file system operation.It provides a more intuitive and simple way to handle files and folders so that developers can complete these tasks faster.
In summary, the FS Extra framework provides a set of advanced features by extending the Java standard file system API to make the file system operation more convenient.By using the FS EXTRA framework, developers can create, copy, move, delete files and folders more easily, and can more conveniently perform the traversing and other operations of the file system.
