Why does adding a semicolon after 'for (…)' change the meaning of my program so dramatically?

Question

I wrote the following class:

  public class TestOne {
     public static void main(String[] args) {
        int count = 0;
        for (int i = 0; i < 100         


        

Answer 1

By adding that semicolon, you are declaring the for statement without a block to loop.

This causes count++ to only be executed once when it's passed, rather than 100 times when it's looped over.
