Concurrent parallel

Concurrency is instantiated once, and concurrent calls need to wait for locks

Parallelism is multiple instantiations, all the same, without waiting for a lock

Introduction to Java multithreading concurrency

  • I divide concurrency into
  • Thread creation and understanding
  • Synchronized (jdK1.5) and synchronized (1.5
  • Thread pools

Concurrent parallel

Concurrency is instantiated once, and concurrent calls need to wait for locks

  • It doesn’t have to worry too much about concurrency and high memory usage

 

Parallelism is multiple instantiations, all the same, without waiting for a lock

  • There’s a lot of memory to worry about, and 100 parallel objects for each new object take up a lot of space
