5、 Data structure and algorithm

Which data structures ( Line , chain , Pile up , Stack , queue ) And in Java Where is it useful .8 Big algorithm ( Time complexity , Spatial complexity , Memory ,CPU Influence ) And its application .KMP Search algorithm , Two points search , A recursive algorithm ( How to write it , Memory impact ). Count 、 Figure and its application .hash surface , And its application in practical work .

Two 、 Database part

Recommended reading ：《 High performance MySQL》 《MySQL Technology insider :InnoDB Storage engine ( The first 2 edition )》

3、 ... and 、 Open source framework part

Spring As a lightweight Java Development framework , The idea of interface oriented programming runs through the whole Java System application , So in Java You are often mentioned in an interview .

Four 、 Distributed high concurrency architecture
