Code ability is the basic skill. The Java language itself includes all aspects of the language, including the understanding of concurrency, memory usage and Java operation and maintenance. Besides the language itself, can you have a clear understanding of the frameworks commonly used in the community, including spring, including whether he has a clear understanding and rich experience in ioc, aop, orm, web mechanism, etc.
