java abstract classes and interfaces

An important point in the object-oriented design process is how to abstract, that is, to establish an ideal one-to-one mapping relationship between elements in the "problem space" and elements in the "solution space". Abstract classes and interfaces are the products of the abstraction process.

Android process communication mechanism AIDL

AIDL stands for Android Interface Definition Language, which is Android interface description language. It sounds very profound, but its essence is an auxiliary tool for generating inter-process communication interfaces. It exists in the form of an .aidl file. All the developer needs to do is to define the interface for inter-process communication in the file. When compiling, the IDE will generate a .java file that can be used by the project based on our .aidl interface file. , which is somewhat similar to what we call "syntactic sugar".

Basic knowledge of running java programs

Each JVM thread creates a private thread stack when it is started. A jvm thread stack is used to store stack frames. The jvm thread stack is very similar to the stack in C language. It is responsible for managing local variables and some operation results, and is also involved in function calls and function returns. The size of the running thread stack in the JVM specification can be fixed or dynamically allocated, or it can be calculated according to certain rules. Different jvm's implementation of the stack will be different. Some may provide developers with ways to control the initial size of the jvm thread stack; for dynamic allocation, they may also provide settings for the jvm's maximum and minimum values.

java garbage collection

In Java, when an object does not have any references, it becomes garbage. If it is not recycled in time and the memory is released, the garbage will accumulate more and more, and eventually out of memory!, and the JVM will stop running.
