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
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
{
Path path
= Paths.get(
"E:\\Tutorials\\file.txt");
FileStore fs
= Files.getFileStore(path);
System.out.println("FileStore Name: "
+ fs.name());
boolean isReadOnly = fs.isReadOnly();
System.out.println("FileStore isReadOnly:"
+ isReadOnly);
}
}
|
Output: Program 2:
Java
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
{
Path path
= Paths.get(
"C:\\Movies\&# 092 ;&# 048 ; 01 .txt");
FileStore fs
= Files.getFileStore(path);
System.out.println("FileStore Name: "
+ fs.name());
boolean isReadOnly = fs.isReadOnly();
System.out.println("FileStore isReadOnly:"
+ isReadOnly);
}
}
