Interesting Java Problems

AnimalFarm.java

public class AnimalFarm {
   public static void main(String[] args) {
      final String pig = "length: 10";
      final String dog = "length: " + pig.length();
      System.out.println("Animals are equal: " + pig == dog);
   }
}

Increment.java

public class Increment {
   public static void main(String[] args) {
      int j = 0;

      for (int i = 0; i < 100; i++) {
         j = j++;
      }

      System.out.println(j);
   }
}
