The arraycopy() method can be used to copy quickly an array of any type from one place to another. This is much faster than the equivalent loop written out longhand in Java. Here is an example of two arrays being copied by the arraycopy() method. First,
originalArrayList.addAll(copyArrayofList); Please keep on mind whenever using the addAll() method for copy, the contents of both the array lists (originalArrayList and copyArrayofList) references to the same objects will be added to the list so if you modify any one of them then copyArr...

实际上,我们只是把copyClass1所指向的在堆(Heap)中的地址赋给了copyClass2. 因此导致了改变了copyClass2.X的值后copyClass1.X的值也被改变。 1. 拷贝原型 为了在Heap中重新创建一片新的地址,我们有如下方案可以选择: 1. 直接用Setter和Getter复制

arraysize arraysize参数用于SQL*Plus 每一次fetch数据的行数,缺省值为15,有效值是1到5000。当扫描了arraysize 行后,停止扫描,返回数据到sqlplus客户端,然后继续扫描。 这个过程就是统计信息中的SQL*Net roundtrips to/from client。因为arraysize 默认是15行,那么就有一个问题,因为我们一个block 中的记录数一般都...
