Ruby learning thread

In Ruby, thread objects are also used to represent threads.

Threads = [] 10. times do thread = thread. new do 10. times {| I | print I; $ stdout. flush; sleep rand (5)} End threads <threadendthreads. each {| thread. join}

The join here is different from the join in the array. The join here means that the main program will wait until the thread is executed. Join (n) specifies to wait for n seconds. If it exceeds the limit, the thread will be killed.

In addition, the thread class has corresponding methods to control the entire thread group. thread. List. Each {| thread | .......}

Other thread Methods: Run, stop
