Question

Create a program
It should read 4 numbers with possible decimal places from a file named data.txt and find the range of the numbers.

The range is the maximum number minus the smallest number.

You can use the Math method Math.min and Math.max to find the smaller or larger of two numbers. Solve this problem by using these methods. DO NOT USE if statements from a future chapter.

use of Math.min

Math.min(22.0, 21.0) will return 21.0, the smaller of the two parameters.

Math.max(-23,0) will return 0, the larger number of the two parameters.

Your program should read the data.txt file and output a single statement like this example:

range of 22.0, 6.1, 2.2, 23.4 is 21.2

Explanation / Answer

please rate - thanks

import java.util.*;
import java.io.*;
public class FileIn
{public static void main(String[] args)throws FileNotFoundException
{double num,maxx,minn;
int i;
System.out.print("range of ");
Scanner input=new Scanner(new File("numbers.txt"));
num=input.nextDouble();
maxx=num;
minn=num;
System.out.print(num+", ");
for(i=1;i<4;i++)
    {num=input.nextDouble();
     System.out.print(num+", ");
    maxx=Math.max(maxx,num);
    minn=Math.min(minn,num);
     }
System.out.println(" is "+(maxx-minn));
           

}
}
