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); } } Output: References: https://docs.oracle.com/javase/10/docs/api/java/nio/file/FileSystem.html#isReadOnly() Like Article Suggest improvement Previous Files isHidden() method in Java with Examples Next FileStore getTotalSpace() method in Java with Examples Share your thoughts in the comments Add Your Comment Please Login to comment...
