Program 5.5: A for Loop that Counts Backwards

for loops do not always work smoothly. For instance consider the following program:

//Count to ten??

class BuggyCountToTen  {

  public static void main (String args[]) {
  
    for (int i=1; i <= 10; i = i - 1) {  
      System.out.println(i);
    } 
    System.out.println("All done!");

  }

}

This program counts backwards. There's nothing fundamentally wrong with a program counting backwards, but the exit condition is that i is bigger than ten. Since i is never going to be bigger than ten in this program, the program never stops.
