Well, I seem to have some little error. Purpose: Finding Max and Min numbers from txt file by inputting four numbers. Then I calculate the Range by using (Max - Min)
Problem: It does great with positive numbers. However, when I input negative numbers, calculation seems to be off.
For example 98 -46 74 -66 it would give me 140.0, in which the real answer is 172.
I.e#2 35 -16 -84 -99 it would give me 99, answer would be near 134.
Here is my work -
import java.util.*;
import java.io.*;
public class Range4 {
public static void main (String [] args) throws FileNotFoundException
{
Scanner fin = new Scanner(new FileReader("data.txt"));
double range;
int count = 1;
double integer = 0.0;
double max = 0.0;
double min = 999.0;
integer = fin.nextDouble();
while( fin.hasNext() ) {
count++;
integer = fin.nextDouble();
if(integer >= max)
{
max = Math.max(max,integer);
}
if(integer <= min)
{
min = Math.min(min,integer);
}
}
range = max - min;
System.out.println("range is " + range);
}
}Just need a little guidance. Do I have to do another loop, where I have to do something with the negatives? Do I have to initialize the max to another number besides 0? Any help is appreciated.
