Main.java:10: error: incompatible types: cannot infer type arguments for PriorityQueue<>
    PriorityQueue<Long> q = new PriorityQueue<>((i1, i2) -> {

    reason: cannot infer type-variable(s) E
      (argument mismatch; bad return type in lambda expression
        possible lossy conversion from long to int)
  where E is a type-variable:
    E extends Object declared in class PriorityQueue
