The method java.io.File.canWrite() is used to check whether the file can be written to in Java. This method returns true if the file specified by the abstract path name can be written to by an application and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo {    public static void main(String[] args) {       try {          File file = new File("demo1.txt");          file.createNewFile();          System.out.println("The file can be written to? " + file.canWrite());       } catch(Exception e) { ... Read More

The method java.io.File.canRead() is used to check whether the file can be read in Java. This method returns true if the file specified by the abstract path name can be read by an application and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo {    public static void main(String[] args) {       try {          File file = new File("demo1.txt");          file.createNewFile();          System.out.println("The file can be read? " + file.canRead());       } catch(Exception e) {       ... Read More

The method java.io.File.isHidden() is used to check whether the given file specified by the abstract path name is a hidden file in Java. This method returns true if the file specified by the abstract path name is hidden and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo {    public static void main(String[] args) {       try {          File file = new File("demo1.txt");          file.createNewFile();          System.out.println("Is file hidden? " + file.isHidden());       } catch(Exception e) {   ... Read More

The method java.io.File.isFile() is used to check whether the given file specified by the abstract path name is an existing file in Java. This method returns true if the file specified by the abstract path name is a file and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo {    public static void main(String[] args) {       try {          File file = new File("demo1.txt");          file.createNewFile();          System.out.println("Is file? " + file.isFile());       } catch(Exception e) {   ... Read More

The method java.io.File.isDirectory() checks whether a file with the specified abstract path name is a directory or not. This method returns true if the file specified by the abstract path name is a directory and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo {    public static void main(String[] args) {       try {          File file = new File("demo1.txt");          file.createNewFile();          System.out.println("Is directory? " + file.isDirectory());       } catch(Exception e) {          e.printStackTrace();   ... Read More

The method java.io.File.exists() is used to check whether a file exists or not. This method returns true if the file specified by the abstract path name exists and false if it does not exist.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo {    public static void main(String[] args) {       try {          File file = new File("demo1.txt");          file.createNewFile();          System.out.println("File exists?
