Several hundred years ago, humans were nearly exterminated by giants. Giants are typically several stories tall , seem to have no intelligence, devour human beings and, worst of all, seem to do it for the pleasure rather than as a food source. A small percentage of humanity survived by walling themselves in a city protected by extremely high walls. Fortunately, the weapons were invented in recent years found effective to kill the titans. Problem statement As a programmer, you need to build a tower defence game in JAVA which allows the player to protect the residents within the wall from the titans.
