List<Object> myList = new ArrayList<>();
//This line will throw an ERROR incompatible types required: boolean found: List<Object>
if(myList){//basically you need a boolean expression inside the if...
  
}
if(myList != null){//works fine because checking against null returns a boolean
  //do stuff
}
//the one trick you can do, is to check for a truthy boolean
boolean bool = true;
if(bool){
  //this code will get run even without checking for (bool == true)
}
