io in addition to file treatment inward Java

I/O as well as File Handling inward Java.
 
There are 3 ways available for reading input:
i) Scanner

ii) DataInputStream

iii) BufferedReader
---------------
Using java.util.Scanner is the easier as well as includes many methods to banking enterprise agree input information is valid to read.

Example:---------------
package javaiooperations;
import java.util.Scanner;
public flat ReadInput {
public static void main(String [] args){
    Scanner scan = novel Scanner(System.in);
   
    System.out.println("Enter Your Name");
    String s1 = scan.nextLine();
    System.out.println("Your Name is: " + s1);
   
    System.out.println("Enter Your City Name");
    String s2 = scan.next();
    System.out.println("Your City Name is: " + s2);
   
    System.out.println("Enter Your Number");
    int a = scan.nextInt();
    System.out.println("Your Number is: " + a);
   
    System.out.println("Enter Your City Name");
    double b = scan.nextDouble();
    System.out.println("Value is: " + b);
    scan.close();
}
}

File treatment inward Java----------------------
Two categories of File System Operations

i) High flat operations / External operations

Create a folder

delete a folder

create a text file

delete a text file etc...

ii) Low flat operations / Internal operations

Read data

Write information etc...
------------------------
Using File Class nosotros tin perform High flat operations
Examples:
1) Create a Folder
package javaiooperations;

import java.io.File;

public flat CreateFolder {
   
    populace static void main(String [] args){
        File fileObject = novel File("C:/Users/G C Reddy/Desktop/Selenium");
        fileObject.mkdir();
        }
}
---------------------------------
2) Check the beingness of Selenium Folderpublic static void main(String [] args){
        File fileObject = novel File("C:/Users/G C Reddy/Desktop/UFT");
        boolean a = fileObject.exists();
        System.out.println(a);
        }
-------------------------------------
3) Delete a Folder
public static void main(String [] args){
        File abc = novel File ("C:/Users/G C Reddy/Desktop/Selenium");
        abc.delete();
        boolean a = abc.exists();
        //System.out.println(a);
        if (a == true) {
            System.out.println("Folder exists");
        }
        else{
            System.out.println("Folder doesn't exist");   
        }
        }
-----------------------------------
4) Create a Text file
public flat CreateFolder {
   
    populace static void main(String [] args){
        File abc = novel File ("C:/Users/G C Reddy/Desktop/Selenium.txt");
        displace {
            abc.createNewFile();
        } select handgrip of (IOException e) {
            // TODO Auto-generated select handgrip of block
            e.printStackTrace();
        }
-------------------------------------------
5) Delete a text file    populace static void main(String [] args){
        File abc = novel File ("C:/Users/G C Reddy/Desktop/Selenium.txt");
        abc.delete();
       
    }
------------------------------------
