The purpose of this tutorial is to use a separate layer written in Java to access the tables in the database, which is often called the data Access Layer (DAL) The biggest advantage of using the DAL is that it simplifies access to the database by using several methods like insert () and find (), rather than always doing a link first and then executing some queries. The layer handles all database-related calls and queries internally. Creating a Data

This rookie just contact Java a week, to its understanding is not deep, can only intuitively feel it. The personal sense and C + + are syntactically similar (actually just pair), first using two sample programs to show the face of Java programs. Example one: Classic GCD and LCM for two integer numbers. (The Euclidean algorithm is more typical) Package LCM and GC
