class MyClass {
  int height;

  MyClass() {
    System.out.println("Planting a seedling");
    height = 0;
  }

  MyClass(int i) {
    System.out.println("Creating new Tree that is " + i + " feet tall");
    height = i;
  }

  void info() {
    System.out.println("Tree is " + height + " feet tall");
  }

  void info(String s) {
    System.out.println(s + ": Tree is " + height + " feet tall");
  }
}

public class MainClass {
  public static void main(String[] args) {
    MyClass t = new MyClass(0);
    t.info();
    t.info("overloaded method");
    // Overloaded constructor:
    new MyClass();
  }
}

Creating new Tree that is 0 feet tall
Tree is 0 feet tall
overloaded method: Tree is 0 feet tall
Planting a seedling
