In the body of the method, a new variable "i" is declared. The new "i" is local to the method, and it's different than the static "i" that is declared in the class. When we say "this.i" we are getting the static "i" of this instance -- not the local "i".

public class Honley {
  public static int i = 99;
  public static void main(String argv[]) {
    Honley h = new Honley();
    h.wine();
  }
  public void wine() {
    i = 10;
    int i = 20; //local variable declared
    System.out.println("local i is " + i);
    System.out.println("this.i is " + this.i);
  }
}
