After learning the basic grammar, I made a student management system (necessary for university course design ~), and consolidated the python grammar. Next, I wil ...

Three sequential containers: vector, list, deque Difference: How elements are accessed and the cost of operations related to adding or deleting elements. vector: Supports fast random access (i.e. arbitrary access, distinguished from disk, tape, etc. which requires seek and rewind access) list:Supports ...

Yesterday we looked briefly at the use of Unsafe. Today we look at how atoms in JUC use Unsafe and how they work!   1. Simple use of AtomicLong Also remember that in the last blog we used the volatile keyword to modify a variable of type int, and then two threads did 10,000 + 1 operations on the variable, and the result wasn't 20,000. Now when ...
