Slip 22 - B) Write a java program for the following: 1. To create a file. 2. To rename a file. 3. To delete a file. 4. To display path of a file.

Solution :

import java.io.*;

import java.util.*;

class Slip22B {

    public static void main(String args[]) throws IOException{

        Scanner  br = new Scanner(System.in);

        System.out.println("1. Press 1 Create File\n2. Press 2 Rename a File\n3. Press 3 Delete a File\n4. Press 4 Display Path of a File");

        System.out.print("Enter File Name : ");

        String str = br.nextLine();

        File file = new File(str);

        System.out.print("Enter Number : ");

        int num = br.nextInt();

        switch(num){

            case 1 :

                if (file.createNewFile()) {

                    System.out.println("File created : " + file.getName());

                } else {

                    System.out.println("File already exists.");

                }

            case 2 :

                System.out.print("Enter New File Name : ");

                String newone = br.nextLine();

                File newfile =new File(newone);

                if(file.renameTo(newfile)){

                    System.out.println("File renamed");

                }else{

                    System.out.println("Sorry! the file can't be renamed");

                }

            break;

            case 3 :

                if (file.delete()) {

                    System.out.println("Deleted the file: " + file.getName());

                } else {

                    System.out.println("Failed to delete the file.");

                }

            break;

            case 4 :

                System.out.println("File Location : " +file.getAbsolutePath());

            break;

            default : System.out.println("Wrong Number ..!");

            break;

        }

    }

}

Output:
