注:本文来源于 <  java 实现往oracle存储过程中传递array数组类型的参数  >最近项目中遇到通过往存储过程传递数组参数的问题, 浪费了N多个小时,终于有点头绪. 具体的代码就不写上了,因为项目中存储过程的调用方法全部是封装好的(好像现在都这样,都姓3层,嘿嘿)  原理: 1.一维数组 A.单纯的一维数组的话,直接建立一个table类型就可以  TYPE TYPE_VARCHAR AS TABLE OF VARCHAR2(200); 2.多维数组 A.多维数组就要稍加修改了,如二…

Java数组 在Java中,数组是用来存放同一种数据类型的集合,注意只能存放同一种数据类型. 用类封装数组实现数据结构 数据结构必须具有以下基本功能: ①.如何插入一条新的数据项 ②.如何寻找某一特定的数据项 ③.如何删除某一特定的数据项 ④.如何迭代的访问各个数据项,以便进行显示或其他操作 而我们知道了数组的简单用法,现在用类的思想封装一个数组,实现上面的四个基本功能: class EasyAarray{ //数据结构:简易数组 private int[] ins; //一维整型数组 priv…

题目描述: Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). You are given a target value to search. If found in the array return its index, otherwise return -1. You may assume no…

题目描述: Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input arra…

题目描述: Given an array of integers that is already sorted in ascending order, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where in…
