Java Path get()

In this guide, you will learn about the Path get() method in Java programming and how to use it with an example.

1. Path get() Method Overview

Definition:

The get() method of the Path interface in the Java NIO (New I/O) package is used to obtain a Path representing a file or directory on the filesystem.

Syntax:

Path.get(String first, String... more)

Parameters:

- first: The initial component of the path.

- more: Additional components of the path. This argument allows for the creation of paths with multiple components in a single call.

Key Points:

- The get() method combines the initial path and any subsequent components to form the complete path.

- This method is typically used when constructing paths in a platform-independent manner.

- If a SecurityManager is present, then its checkRead method is called to ensure that read access to the file is permitted.

2. Path get() Method Example

import java.nio.file.Path;
import java.nio.file.Paths;

public class PathGetExample {
    public static void main(String[] args) {
        // Constructing a path to a file
        Path filePath = Paths.get("C:", "Users", "JohnDoe", "Documents", "myfile.txt");
        System.out.println("File path: " + filePath);

        // Constructing a path to a directory
        Path dirPath = Paths.get("/home", "johndoe", "projects");
        System.out.println("Directory path: " + dirPath);
    }
}

Output:

File path: C:\Users\JohnDoe\Documents\myfile.txt
Directory path: /home/johndoe/projects

Explanation:

In the example, we first construct a path to a file named myfile.txt that resides in the Documents directory of the user JohnDoe on a Windows system. This is demonstrated by the use of drive letters and the use of backslashes in the printed path. 

Next, we construct a path to a directory named projects that reside in the home directory of the user johndoe on a UNIX-like system. This is evident by the use of forward slashes in the printed path.
