是一种使用简单的Java数据库连接(JDBC)技术来调用ORACLE数据库中存储过程的方法。JDBC是Java语言访问数据库的标准API,它提供了一组用于连接数据库、执行SQL语句和处理结果的类和接口。 存储过程是一组预编译的SQL语句集合,可以在数据库中进行存储和重复使用。它们可以接受参数并返回结果,可以在应用程序中通过调用存储过...
to sum up This article mainly introduces the generation of AOP proxy objects, parsing the XML configuration file and creating the corresponding BeanDefinition, and finally injecting it into the container. It only introduces the general implementation ideas. The specific code implementation has been uplo...
Then, we generate the hash value of our input data, which is a byte array Finally, we transform the byte array into a hex string, a hash is typically represented as a 32-digit hex number 4.3. Have We Mined the Block Yet? Everything sounds simple and elegant so far, except for the ...

Given a set of non negative integers and a target value, find if there exists a subset in the given set whose sum is target. Solution 1. Enumerate all possible subsets and check if their sum is the target The runtime of this solution is O(2^n). This enumeration algorithm is similar ...
