 > We are pleased to present Alibaba Java Coding Guidelines which consolidates the best programming practices over the years from Alibaba Group's technical teams. A vast number of Java programming teams impose demanding requirements on code quality across projects as we encourage reuse and better understanding of each other's programs. We have seen many programming problems in the past. For example, defective database table structures and index designs may cause software architecture flaws and performance risks. Another example is confusing code structures being difficult to maintain. Furthermore, vulnerable code without authentication is prone to hackers’ attacks. To address these kinds of problems, we developed this document for Java developers at Alibaba.
