import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;


public class Lab8Num1 {

   
    public static void main(String[] args) {
         File inFile = new File("lab8.in");
          Scanner fileInput = null;
        try {
          fileInput = new Scanner(inFile);
        } catch (FileNotFoundException ex) {
            //Logger.getLogger(Lab10.class.getName()).log(Level.SEVERE, null, ex);
        }
        //get first number and make it the biggest;
        //loop through the file
        //getting doubles and comparing with current "biggest"
       
       
        System.out.println("The biggest number was " + biggest);
                }

Explanation / Answer

The program is as follows:

import java.io.File;

import java.io.FileNotFoundException;

import java.util.Scanner;

public class Lab8Num1 {

public static void main(String[] args) {

//Declaring variable to be used for storing and for output

double biggest,temp;

//Creating file to read numbers

File inFile = new File("lab8.txt");

//Stream to read data from file

Scanner fileInput = null;

try {

fileInput = new Scanner(inFile);

} catch (FileNotFoundException ex) {

//Logger.getLogger(Lab10.class.getName()).log(Level.SEVERE, null, ex);

}

//get first number and make it the biggest;

biggest=fileInput.nextDouble();

//loop through the file

while(fileInput.hasNextLine())

{

//getting doubles and comparing with current "biggest"

temp=fileInput.nextDouble();

if(temp>biggest)

biggest=temp;

}

System.out.println("The biggest number was " + biggest);

}

}

Output

The biggest number was 10.6
