FileSystem isReadOnly() method in Java with Examples

The isReadOnly() method of a FileSystem class is used to check whether or not this file system allows only read-only access to its file stores. If the file system allows only read access to its file stores then this method will return true, else false.

Syntax:

public abstract boolean isReadOnly()

Parameters: This method accepts nothing.

Return value: This method returns true if, and only if, this file system provides read-only access.

Below programs illustrate the isReadOnly() method:
Program 1:




// Java program to demonstrate
// FileSystem.isReadOnly() method
  
import java.nio.file.FileSystem;
import java.nio.file.Path;
import java.nio.file.Paths;
  
public class GFG {
  
    public static void main(String[] args)
    {
        // create object of Path
        Path path
            = Paths.get(
                "C:\\Movies\\document.txt");
  
        // get FileSystem object
        FileSystem fs = path.getFileSystem();
  
        // apply isReadOnly() methods
        boolean answer = fs.isReadOnly();
  
        // print
        System.out.println("isReadOnly: "
                           + answer);
    }
}


Output:

Program 2:




// Java program to demonstrate
// FileSystem.isReadOnly() method
  
import java.nio.file.FileSystem;
import java.nio.file.Path;
import java.nio.file.Paths;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // create object of Path
        Path path
            = Paths.get(
                "E:// Tutorials// file.txt");
  
        // get FileSystem object
        FileSystem fs = path.getFileSystem();
  
        // apply isReadOnly() methods
        boolean answer = fs.isReadOnly();
  
        // print
        System.out.println(fs + "is ReadOnly = "
                           + answer);
    }
}
