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?
