This program loops through fileLoop.txt, computation, and display results
package charialoar:
import javautilScanoer;
import java io *;
//
public class Charielaer {
public static void main(String[] aras) throws LQEXCertion
{
//Create a reference to the physical file
File loopfile = new File("fileLoop.txt")
// connect a Scanner to the file
Scanner getAl = new Scanner(loopfile, );
int num = 0, square = 0:
while(num != -1){
num = getAlrextInt(2;
square = num * num:
Sxstemeutprintla("The square of " + num + " is " + square);
