FileStore isReadOnly() method in Java with Examples

0 1 1 minute read

The isReadOnly() method of a FileStore class is used to return true if this file store is read-only else false. A file store is called read-only if it does not support write operations or other changes to files. An IOException to be thrown if an attempt to create a file, open an existing file for writing, etc occurs. Syntax:

public abstract String isReadOnly()

Parameters: This method accepts nothing. Return value: This method returns true if, and only if, this file store is read-only. Below programs illustrate the isReadOnly() method: Program 1:

Java

// Java program to demonstrate
// FileStore.isReadOnly() method
 
import java.io.IOException;
import java.nio.file.FileStore;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
 
public class GFG {
 
    public static void main(String[] args)
        throws IOException
    {
 
        // create object of Path
        Path path
            = Paths.get(
                "E:\\Tutorials\\file.txt");
 
        // get FileStore object
 
        FileStore fs
            = Files.getFileStore(path);
 
        // print FileStore name
        System.out.println("FileStore Name: "
                           + fs.name());
        // if file is readable
        boolean isReadOnly = fs.isReadOnly();
        System.out.println("FileStore isReadOnly:"
                           + isReadOnly);
    }
}

Output: Program 2:

Java

// Java program to demonstrate
// FileStore.isReadOnly() method
 
import java.io.IOException;
import java.nio.file.FileStore;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
 
public class GFG {
 
    public static void main(String[] args)
        throws IOException
    {
 
        // create object of Path
        Path path
            = Paths.get(
                "C:\\Movies\092;048;01.txt");
 
        // get FileStore object
 
        FileStore fs
            = Files.getFileStore(path);
 
        // print FileStore name
        System.out.println("FileStore Name: "
                           + fs.name());
        // if file is readable
        boolean isReadOnly = fs.isReadOnly();
        System.out.println("FileStore isReadOnly:"
                           + isReadOnly);
    }
