The BlockingQueue interface in Java includes an operation, offer(),that uses balking to add an element to the end of the queue if possible, andanother operation, put(), that uses guarded suspension to add an element tothe end of the queue. Under which circumstances would you use one of theseoperations instead of the other, and why?題目大概是問(wèn)什么時(shí)候用 offer() 什么時(shí)候用 put()， 因?yàn)樗麄兊膇mplemention其實(shí)不一樣，offer 是用 balking，就是如果出錯(cuò)就忽視, 或者throw exception。 put 就是如果滿了就call wait()。 所以我的問(wèn)題是什么時(shí)候用這兩個(gè)方法？
