Java threads have two features:Visibility and orderlinessData Interaction cannot be transmitted between multiple threads. Interaction between threads can only be achieved through shared variables. An object of the Count class is shared among

I. Concepts, principles, distinctionsMultithreading in Java is a preemptive mechanism rather than a time-sharing mechanism. Threads have the following states: Can run, run, block, die.       The preemption mechanism refers to having multiple threads
