Arrays are contiguous sections within memory, so to create an array you would need to reserve a chunk of memory which is of size n * sizeof (type), where n is the amount of items you would like to store and the sizeof (type) would return the size, in bytes which the JVM would need to represent that given type. WitrynaStack backed by a dynamic array. Pushing onto the stack can be implemented by appending a new element to the dynamic array, which takes amortized O(1) time and worst-case O(n) time. Popping from the stack can be implemented by just removing the last element, which runs in worst-case O(1) (or amortized O(1) if you want to try to …
