Learning experience

After nearly half a month of ups and downs, I finally finished watching the video of Jack Ma's J2SE tutorial. Some other things I had to deal with always interrupted my arrangement. After watching the video, I think things are really very basic. What impressed me most is the memory analysis, IO and thread of program execution. Who did learn VB and VB before. NET or C.

First, I think the first question for a beginner in Java may be how to configure the Java execution environment. In fact, there are a lot of online tutorials, and Baidu can solve the problem very well.

The knowledge about internal and anonymous classes is the same as that of JavaScript. The object-oriented methods, such as VB. NET, C #, JavaScript, and J2SE, are similar. This also allows me to learn about J2SE with less fear of new things and more familiarity with old friends.

At the same time, Java is the foundation of Android, and it has played a role in the development of Android.

This video focuses on object orientation, and the knowledge about memory analysis runs through the entire video (this should be the top priority ). For exception handling, videos are also listed separately. We should also note that we should correctly understand bugs in the code.

When learning with other programming-oriented languages you have learned before, you will find it Easy to understand a new object-oriented programming language.

In short, check the API documentation no matter what the situation occurs (remember ).
