g Create your own data file consisting of integer, double or String values. Create your own unique Java application to read all data from the file echoing the data to standard output. After all data has been read, display how many data were read. For example, if 10 integers were read, the application should display all 10 integers and at the end of the output, print "10 data values were read" Demonstrate your code compiles and runs without issue. Respond to other student postings by enhancing their code to write the summary output to a file instead of standard output.

See explaination

Explanation:

//ReadFile. java

import java. io. File;

import java. io. FileNotFoundException;

import java. util. Scanner;

public class ReadFile

{

public static void main (String[] args)

{

int elementsCount=0;

//Create a File class object

File file=null;

Scanner fileScanner=null;

String fileName="sample. txt";

try

{

//Create an instance of File class

file=new File (fileName);

//create a scanner class object

fileScanner=new Scanner (file);

//read file elements until end of file

while (fileScanner. hasNext ())

{

double value=fileScanner. nextInt ();

elementsCount++;

}

//print smallest value

System. out. println (elementsCount+" data values are read");

}

//Catch the exception if file not found

catch (FileNotFoundException e)

{

System. out. println ("File Not Found");

}

}

}

Sample output:

sample. txt

10

20

30

40

50

output:

5 data values are read
