Start to focus

  • hit — The content of the line , For medium speed ( Set the playback speed to 1.6 times ), Know that you can , If you are interested, you can knock

  • Framed as must see , Slow down 1.3 Look , understand , And make sure you type the code , And take notes !

One 、 Language foundation ( This is the most basic thing , There's nothing to row , All will , Five days )

A lot of people will ask , those JVM, Concurrency, etc ( Senior engineers use ), Then why do I just need to know ?

  • Because we're actually developing , Not from scratch , It is to develop on the basis of predecessors , Others have put these things in it , We just need to be able to use it .

  • Developers are , Leave the complicated to yourself , Leave the simple to others .

  • Like cars , You can use it when you buy a car , But when you become a car designer , Then you have to be able to design these things .

  • Of course ,80% The programmer (15K And the following ) It's all in the stage of being able to use , So my understanding of the mark is OK , Enough knowledge for beginners !

today , As the first javase Basics ( One month ) So here's the content of , We will analyze other contents later .
