1. Exception mechanismThe exception mechanism is what the program does when an error occurs. Specifically, the exception mechanism provides a secure channel for program exits. When an error occurs, the process of executing the program changes, and

The two most commonly used subclasses in collection (List collection, set collection)List interface1, it is an element of an orderly collection of access. The order here is not to say that the set is stored in ascending order, but rather how the

A linked list is a non-sequential, non-sequential storage structure on a physical storage unit, and the logical order of the data nodes is achieved by the order of the pointers in the linked list.Linked list----Java implementation:1

In practical applications, sometimes we need to create some delayed and periodic tasks. For example, we want to make a log every one hour after our program starts. JDK provides two methods to create delayed periodic tasks. TimerTimer is Java. A
