min and max priority queue java code example
Example 1: how to take max value from priority queue in java
PriorityQueue maxPriorityQ = new PriorityQueue(Collections.reverseOrder());
Example 2: priority queue max heap in java
//Sol1
PriorityQueue queue = new PriorityQueue<>(10, Collections.reverseOrder());
//Sol2
// PriorityQueue pq = new PriorityQueue<>((x, y) -> y - x);
PriorityQueue pq =new PriorityQueue<>((x, y) -> Integer.compare(y, x));
//Sol3
PriorityQueue pq = new PriorityQueue(defaultSize, new Comparator() {
public int compare(Integer lhs, Integer rhs) {
if (lhs < rhs) return +1;
if (lhs.equals(rhs)) return 0;
return -1;
}
});
