functional programming in the java language

now, this is where the fun bit shows up:


Listing 1. A closure in disguise


Runnable worker = new Runnable()
{
  public void run()
  {
    parseData();
  }
 };


The method parseData is literally enclosed (hence the name "closure")

No, but everything is OOP
int foo = 0; //not an object in java lol
