Php does not need to declare the array size in advance. you can create an array by directly assigning values.

(large GC). Permanent Generation Persistent generations. Contains class/method information for the app, as well as class and method information for the JRE library. The small GC performs very frequently and is extremely fast.A large GC is typically 10 times times slower than a small GC.The size GC emits a "Stop the World" event, which means that the program is interrupted until the GC is complete. That's why we say that frequent GC can cause user

[1] [Python basics] using list and tuple[3]listOne of the data types built into Python is the list: lists. A list is an ordered set of elements that can be added and removed at any time.For example, by listing the names of all the classmates in the class, you can use a list to indicate:>>> classmates = ['Michael'Bob' Tracy']>>> classmates['Michael' ' Bob ' ' Tracy ']classmatesA variable is a list. len()the

In RxJava 1.x Understanding-1, we talked about the simple use of RxJava, but that's not enough becauseThe input data---> is manipulated by listeners (feeds), or the response is processed and the new data is generated, or events are sent to listeners--listeners execute their own methods.The Rxjava can also transform the input data, generating new data (which can be complex data) rather than simple event trig
