// This program demonstrates the basics of a for loop. The for loop
// is used to execute the same code multiple times. It is done (commonly)
// by using an int variable as a counter, and incrementing that variable 
// until it reaches some stopping point.
public class ForLoopExample {
   public static void main(String[] args) {
      int x = 5;
      
      // Reminders about variable re-assignment:
      // We can increase x's value by 1 in three different ways.
      // These all do (practically) the same thing
      x = x + 1;
      x += 1;
      x++;
      
      // initialization, test, update
      // we usually start i at 1 (or 0), and we usually use i++
      // what goes in the middle in the test depends on how many times you want the loop to execute
      for (int i = 1; i <= 4; i++) {
         System.out.println("Second favorite movie: Hogfather");   
      }
      System.out.println("For loop is done.");

      // Same thing, but spread across multiple lines.
      // Can be helpful to do this with the java debugger:
      for (
         int i = 1;   // initialization: set a starting value for the forloop counter
         i <= 4;      // test: use the forloop counter to make an expression that determines how long to continue looping
         i++          // update: define how to update the counter between loop iterations
      ) {
         // inside these braces is the forloop body
         System.out.println("Second favorite movie: Hogfather");   
         System.out.println("Never bad to print out i for testing. i = " + i);
      }
      System.out.println("For loop is done.");
