基于java开发的功能强大、配置灵活的数据库之间的同步工具,和数据产生器一样,均是前段时间因为项目需要编写的小工具,在实际应用场景中,我们经常需要定期将一个数据库的数据同步到另外一个数据库中,常见的一种做法是将源数据库的数据dump为sql文件,然后到目标数据库执行sql文件完成数据库的导入,但是这种方法至少存在以下...
E item;//节点的值Node<E> next;//当前节点的后一个节点的引用(可以理解为指向当前节点的后一个节点的指针)Node<E> prev;//当前节点的前一个节点的引用(可以理解为指向当前节点的前一个节点的指针)Node(Node<E> prev, E element, Node<E>next) {this.item =element;this.next =next;this.prev =prev...

Object[]toArray() Returns an array containing all of the elements in this list in proper sequence (from first to last element). <T> T[]toArray(T[] a) Returns an array containing all of the elements in this list in proper sequence (from first to last element); the runtime type of...
// <E> 泛型标识符 public static <E> void printArray(E[] array) { for(E element : array){ System.out.printf("%s",element); } } 泛型字母的含义 E - Element: 在集合中使用,因为集合中存放的是元素 T - Type: Java类 K - Key: 键 V - Value: 值 N - Number: 数值类型 反射 反射...
This is a classic "bounded buffer", in which a fixed-sized array holds elements inserted by producers and extracted by consumers. Once created, the capacity cannot be changed. Attempts toputan element into a full queue will result in the operation blocking; attempts totakean element from an em...
If an entity reference node or another element node is encountered, recurse (that is, apply the text-extraction procedure to all sub-nodes). Note -From JAXP 1.2 onwards, the JAXP parser does not insert entity reference nodes into the DOM. Instead, it inserts aTEXTnode containing the contents...
