arraylist internal implementation

ArrayList is an array-based implementation, with no capacity constraints.When you delete an element, it does not reduce the size of the array, and you can call ArrayList's trimetosize () to reduce the capacity of the

ArrayList and HashMap are asynchronous, while Vector and HashTable are synchronous. Therefore, Vector and HashTable are thread-safe, while ArrayList and HashMap are not thread-safe. Because synchronization takes machine time, the execution

We generally know the differences between arraylist and rule list:1. arraylist is a dynamic array-based data structure. The arraylist is based on the linked list data structure.2. for Random Access to get and set, arraylist thinks it is better than

Turn from: 76760238Top Notes The implementation of a variable array of size for the list interface. All optional list operations are implemented and all elements, including NULL, are allowed. In addition to implementing the list interface, this
