Introduction The Collections utility class consists exclusively of static methods that operate on or return collections. It contains polymorphic algorithms that operate on collections, "wrappers", which return a new collection backed by a specified collection, Some useful method in Collections class: Let...
after viewing, the controller would communicate with the business logic, which would then get in touch with the Java POJO class to retrieve the data. The phrase "business logic" describes the comprehensive collection of guidelines that specify how data will be handled ...

该方法用于哈希查找,重写了equals方法一般都要重写hashCode方法。这个方法在一些具有哈希功能的Collection中用到。 一般必须满足obj1.equals(obj2)==true。可以推出obj1.hash- Code()==obj2.hashCode(),但是hashCode相等不一定就满足equals。不过为了提高效率,应该尽量使上面两个条件接近等价。7.wait方法 ...
Java内部类(Inner Class) 简单的说,内部(inner)类指那些类定义代码被置于其它类定义中的类;而对于一般的、类定义代码不嵌套在其它类定义中的类,称为顶层(top-level)类。对于一个内部类,包含其定义代码的类称为它的外部(outer)类。 <!--[if !supportLists]-->1<!--[endif]-->Static member class(静态...
