array equality Dec 2nd, 2008, 10:09pm   I have a quick question. I apologize in advance if this has already been addressed. I'm using 152. The following doesn't print anything. Why? Quote: float[]one = {1.1, 2.2, 3.3}; float[]two = new float[3]; arrayCopy(one, two); if(one == two || one.equals(two)) {   println("yes"); } float[]three = new float[6]; float[]four = new float[6]; getMatrix().get(three); getMatrix().get(four); if(three == four || three.equals(four)) {   println("yes2"); }
