Map Class in processing code about como-nos-sentimos

[arturhoo]

It was tested and worked as seen in the code below:

HashMap hm = new HashMap();

void setup(){
  size(200,200);
  background(100,100,100);
  hm.put("a", 4);
  hm.put("b", 3);
  hm.put("c", 5);
  print(hm.get("a"));
  clearHashMap();
  print(hm.get("a"));
}

void draw(){
  if((Integer) hm.get("a") == 4) {
    fill(0,0,0);
    rect(0,0,10,10);
  } else {
    fill(255,255,255);
    rect(100,0,10,10);
  }

}

void clearHashMap() {
  Iterator j = hm.entrySet().iterator();
  int i= 0;
  while (j.hasNext ()) {
    Map.Entry me = (Map.Entry)j.next();
    hm.put(me.getKey(), 0);
  }
}
