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 basic. What impressed me most is the memory analysis, Io and thread of the program running. 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 Runtime Environment. In fact, there are a lot of online tutorials. Baidu can solve this problem easily.

The knowledge about internal and anonymous classes is the same as that of JavaScript. However, for object orientation, whether it is VB. net, C #, JavaScript or j2se are similar, which also makes me learn j2se less fear of new things, more familiar to old friends.

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 ).
