问一:ArrayList和Array的区别? Array(数组)是一种引用类型,主要作用是用来存储数据,即可存储基本数据类型也可存储对象,但在定义一个数组时需要注意:必须指定数组的数据类型及数组长度,即数组中存放的元素个数固定并且类型相同。故我们也可以将Array称作静态数组。
The createNamedQuery method is used to create static queries, or queries that are defined in metadata by using the javax.persistence.NamedQuery annotation. The name element of @NamedQuery specifies the name of the query that will be used with the createNamedQuery method. The query element of ...

Vector和ArrayList几乎是完全相同的,唯一的区别在于Vector是同步类(synchronized),属于强同步类,Vector每次扩容请求其大小的2倍空间,而ArrayList是1.5倍。常用方法:addElement(o),insertElementAt(o,idx),removeElement(o); 可变参数:方法名(int... arr),只能放在参数列表的最后面,其实编译成的class文件将这些元素先封...
