Question

In java

Step 1) Assume that you have tracked monthly BSIT inquires for 10 months. Save the following data into a text file in notepad in the order listed 40 22 17 35 28 17 22 28 25 19

Step 2) Write a java program that reads the monthly BSIT inquires for 10 months from the text file that you created in step 1. Read the monthly inquires from the input file into an array in one execution of the program. Write a sort method to sort the inquiry values lowest to highest. Write a method to calculate the average of the monthly inquiries. Write a method to determine the maximum value. Your program should call the sort, average and maximum methods. Create an output file to which you write the sorted array output, the average value and maximum value.

Answer 1

Please let me know if anything is required

Step1:

Copyable code:

import java.io.FileWriter;
import java.io.IOException;
import java.io.*;
import java.util.*;

class Main
{
public static void main(String[] args) throws IOException
{
  
String filename;
System.out.print("Enter the file name to write the monthly BSIT inquires: ");//filename input from the iser
Scanner sc = new Scanner(System.in);
filename=sc.next();
FileWriter fw=new FileWriter(filename); //to write on the file
  
System.out.println("Enters the BSIT inquires: ");
for (int i = 0; i < 10; i++)
{
int t;
t=sc.nextInt();//taking monthly inquires from the user
fw.write(t+" "); //Writing 10 inquires into the file
}
System.out.println("BSIT inquires written to the file successfully");
//close the file
fw.close();
}
}
