How to do simple memory Analysis in Java Program Development
How to carry out simple memory analysis in Java program development, I believe that many inexperienced people do not know what to do. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.
First of all, the memory is divided into four parts, including stack segment, heap segment, code segment and data segment.
Among them, everything that comes out with the keyword new in our program is stored in heap segment.
The local variables in the program are stored in stack segment. These local variables are automatically released by the system after the execution of the specific method (while the resources in heap segment need to be processed by the java garbage collection mechanism).
Methods in a program are in code segment in memory, and multiple objects share a code space area
Static static variable, which needs to be placed in the data segment in memory
The following is a memory analysis of an example program
Class Demo {
Private int firistNum
Private int secondNum
Public static int temp = 3
Public Demo (int firstNum,int secondNum) {
This.firstNum = firstNum
This.secondNum = secondNum
}
}
Public class Test {
Public static void main (String [] args) {
Demo test = new Demo (3jue 4)
}
}
The following is the process of memory space allocation
The second step of the implementation process
This is the memory space allocation during the execution of the main method, and it is very important to analyze the memory well for the program that analyzes logical errors later.
After reading the above, have you mastered how to do simple memory analysis in Java program development? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
