This program reads in numbers from a file then calculate the the numbers cube (e.g. 4x4x4) The for loop should run from 1-25, since there are 25 pairs of values in the file.
Quote:
import java.io.*;
class FilesPrac2
{
public static void main (String args[])
throws java.io.IOException
{
FileReader fr = new FileReader ("squares.txt");
BufferedReader bfr = new BufferedReader (fr);
final int MAX = 25;
int product = 0;
int cube = 0;
int loopNum = 0;
int even_product = 0;
String input = "";
// This loop will output the even integers the squares
// and calculate and output the cubes of the even numbers.
for (int counter = 1 ; counter <= MAX;)
{
input = bfr.readLine();
loopNum = Integer.parseInt (input);
cube = (counter * counter * counter);
input = bfr.readLine();
even_product = Integer.parseInt (input);
System.out.print (counter + " " + product + " " + cube);
}
fr.close();
}
}
inside the squares.txt file:
0 0
2 4
4 16
6 36
8 64
10 100
12 144
14 196
