Learnings:
This time the review is really very useful, so I look in the summer of knowledge reviewed
The most important foundation: a computer and binary conversion recalled what the computer is stored (bits and bytes relations, etc.) data; also recalled the common commands the command prompt, for which it took a little time to put the summer of MySQL simple CRUD manipulate database commands and command tables were reviewed, Java features: cross-platform; the relationship between the jdk, jre, jvm; identifiers, keywords, constants, variables, basic data types and type conversion to class just also a quick review, there are some grammatical structures circulation, etc. were selected into the brain.
Besides class content today, take to review the homework, mainly began a Java object-oriented learning.
Classes and Objects, class definition, calling the summer also spent the time to look, but now have to see the video review section 12 method, which I have read a lot I have not cooked.
Today, the beginning of object-oriented learning:
The concept of learning classes and objects, the definition of class, create objects. Today I learned a summer vacation did not watch the video knowledge, is to create multiple objects, the object passed by reference (and waste produced); more in-depth understanding of the concept stack heap.
In addition, learning object-oriented features: encapsulation! Then in the evening I also reviewed the textbooks aside, finally he spoke method overloading (1-1 Baidu network disk video section 13) in a multi-state; a class and method names can be the same name, but different argument types or the number of parameters, this will have different functions.
Finished!
