Java并发源码concurrent包 在JDK1.5之前,Java中要进行业务并发时,不管什么情况下,都需要由程序员独立完成代码实现,此时在进行一些并发设计时需要考虑性能、死锁、公平性、资源管理以及如何避免线程安全性方面带来的危害等,往往会采用一些较为复杂的安全策略,加重了程序员的开发负担。 在JDK1.5出现之后,java.util.concurre...

当我们迭代一个ArrayList或者HashMap时,如果尝试对集合做一些修改操作(例如删除元素),可能会抛出java.util.ConcurrentModificationException的异常。 importjava.util.Iterator;importjava.util.List;publicclassAddRemoveListElement{publicstaticvoidmain(String args[]){List<String> list =newArrayList<String>();list.add...
在java语言中,ArrayList是一个很常用的类,在编程中经常要对ArrayList进行删除操作,在使用remove方法对ArrayList进行删除操作时,报java.util.ConcurrentModificationException异常,下面探讨一下该异常的原因以及解决办法。 1 import java.util.ArrayList; 2 import java.util.List; ...
