### Example Two

This program loops through `fileLoop.txt`, performs computations, and displays the results.

```java
package charioloop;

import java.util.Scanner;
import java.io.*;
//
public class Charioloop {

public static void main(String[] args) throws IOException {
// Create a reference to the physical file
File loopFile = new File("fileLoop.txt");

// Connect a Scanner to the file
Scanner getAll = new Scanner(loopFile);
int num = 0, square = 0;

while(num != -1) {
num = getAll.nextInt();
square = num * num;
System.out.println("The square of " + num + " is " + square);
}
getAll.close();
}
}
```
