Implement the following operations of a stack using queues. push(x) -- Push element x onto stack. pop() -- Removes the element on top of the stack. top() -- Get the top element. empty() -- Return whether the stack is empty. ...
Threads are lightweight subprocesses that allow a program to perform multiple tasks simultaneously, taking advantage of the available CPU cores and improving the overall performance of the application. Let’s look at a brief example of multithreading in Java using the Runnable interface: Java 1 2...
以ArrayBlockingQueue为例,来看一下源码, ArrayBlockingQueue源码解析。 在此有几点疑问:对于普通的Queue,put/get 和offer/poll的区别是前者对抛出异常,而后者返回特殊值,对于BlockqingQueue呢,当为空或已满的情况会怎样呢? 撇开其锁的具体实现,其流程就是我们在操作系统课上学习到的标准生产者模式。 阻塞和可中断...
