Study Java It takes a systematic process , Different learning directions need different learning time . at present Java It is widely used in Web Development 、 Big data development 、Android Development and various back-end service development fields , Usually , Study Java From the Web Development begins to learn , Of course, the premise is that you have mastered the basic part .
Java Web Development needs to learn three parts , Namely Java Basic grammar 、Java Web Foundation and framework development .Java The basic grammar part is learning Java The key points and difficulties of language , We need to focus on mastering the class 、 object 、 attribute 、 Method 、 encapsulation 、 Inherit 、 Some concepts such as polymorphism , In addition, a lot of experiments are needed , We need to master a series of experimental methods , This part of study usually takes about a month .
Java The framework part is also a learning focus , For beginners, we can learn from Spring Frame start .Spring After years of development, the framework has formed a huge program system , at present SpringMVC、SpringBoot、SpringCloud Widely adopted , from SpringBoot It's also a good choice to start . The study of this part needs to complete a lot of experiments , It usually takes about a month .
In control Java Web After developing content , If you want to move towards big data , You still need to learn Hadoop Platform related knowledge ,Hadoop The ecosystem of the platform is also complex , Include Hbase、Hive、Pig、Mahout、Zookeeper、Avro And so on , To finish Hadoop The introduction of the platform also needs to be about 3 About months .
After learning Java After the basic content of , Be sure to exercise and improve through practical projects ,Java As a tool , Only in the process of use can we gradually deepen .
