Using the keyword "this" in java

It can be also a way to access information on the current context. For example:

public class OuterClass
{
  public static void main(String[] args)
  {
    OuterClass oc = new OuterClass();
  }

  OuterClass()
  {
    InnerClass ic = new InnerClass(this);
  }

  class InnerClass
  {
    InnerClass(OuterClass oc)
    {
      System.out.println("Enclosing class: " + oc + " / " + oc.getClass());
      System.out.println("This class: " + this + " / " + this.getClass());
      System.out.println("Parent of this class: " + this.getClass().getEnclosingClass());
      System.out.println("Other way to parent: " + OuterClass.this);
    }
  }
}
