Question

Java - Ask user for a file name and dipslay file content. Not working

I'm trying to ask the user to enter a file name called (answers3.txt) and display the content in that file, but can't figure out what I'm doing wrong.

import java.io.IOException;
import java.util.Scanner;

public class importFile {
   public static void main(String[] args) throws Exception {
       Scanner input = new Scanner(System.in);
       System.out.println("Enter File to dispaly: ");
       String fileName = input.nextLine();
      
       java.io.File file = new java.io.File(fileName);
       Scanner input = new Scanner(file);

           while(input.hasNext()) {              
               System.out.println(input.nextLine());
           }
           input.close();          
       }
   }

Explanation / Answer

Hi, I have corrected all issue.

Please let me know in case of any issue.

import java.io.FileNotFoundException;

import java.util.Scanner;

public class importFile {

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

       Scanner input = new Scanner(System.in);

       System.out.println("Enter File to dispaly: ");

       String fileName = input.nextLine();

       try{

           java.io.File file = new java.io.File(fileName);

           Scanner fileScanner = new Scanner(file);

           while(fileScanner.hasNextLine()) {

               System.out.println(fileScanner.nextLine());

           }

           input.close();

           fileScanner.close();

       }catch(FileNotFoundException e){

           System.out.println("Input file is not present");

       }

   }

}
