java-object-oriented features
Encapsulation: refers to hiding the properties and implementation details of an object and only providing public access methods to the outside world.
Benefits:
1. Hide implementation details and provide public access.
2. Improved code reusability.
3. Improved security.
Principles of Encapsulation:
1. Hide content that does not need to be provided to the outside world.
2. Hide the properties and provide public methods to access them.
this: is the object reference of the current class. That is: it represents an object of the current class.
This application scenario;
Solution to local variables and hidden member variables.

Detailed explanation of C++ function inheritance: How to use 'base class pointer' and 'derived class pointer' in inheritance?
May 01, 2024 pm 10:27 PM
In function inheritance, use "base class pointer" and "derived class pointer" to understand the inheritance mechanism: when the base class pointer points to the derived class object, upward transformation is performed and only the base class members are accessed. When a derived class pointer points to a base class object, a downward cast is performed (unsafe) and must be used with caution.
What exactly is self-media? What are its main features and functions?
Mar 21, 2024 pm 08:21 PM
With the rapid development of the Internet, the concept of self-media has become deeply rooted in people's hearts. So, what exactly is self-media? What are its main features and functions? Next, we will explore these issues one by one. 1. What exactly is self-media? We-media, as the name suggests, means you are the media. It refers to an information carrier through which individuals or teams can independently create, edit, publish and disseminate content through the Internet platform. Different from traditional media, such as newspapers, television, radio, etc., self-media is more interactive and personalized, allowing everyone to become a producer and disseminator of information. 2. What are the main features and functions of self-media? 1. Low threshold: The rise of self-media has lowered the threshold for entering the media industry. Cumbersome equipment and professional teams are no longer needed.
TrendForce: Nvidia's Blackwell platform products drive TSMC's CoWoS production capacity to increase by 150% this year
Apr 17, 2024 pm 08:00 PM
According to news from this site on April 17, TrendForce recently released a report, believing that demand for Nvidia's new Blackwell platform products is bullish, and is expected to drive TSMC's total CoWoS packaging production capacity to increase by more than 150% in 2024. NVIDIA Blackwell's new platform products include B-series GPUs and GB200 accelerator cards integrating NVIDIA's own GraceArm CPU. TrendForce confirms that the supply chain is currently very optimistic about GB200. It is estimated that shipments in 2025 are expected to exceed one million units, accounting for 40-50% of Nvidia's high-end GPUs. Nvidia plans to deliver products such as GB200 and B100 in the second half of the year, but upstream wafer packaging must further adopt more complex products.
How to convert MySQL query result array to object?
Apr 29, 2024 pm 01:09 PM
Here's how to convert a MySQL query result array into an object: Create an empty object array. Loop through the resulting array and create a new object for each row. Use a foreach loop to assign the key-value pairs of each row to the corresponding properties of the new object. Adds a new object to the object array. Close the database connection.
AMD 'Strix Halo” FP11 package size exposed: equivalent to Intel LGA1700, 60% larger than Phoenix
Jul 18, 2024 am 02:04 AM
This website reported on July 9 that the AMD Zen5 architecture "Strix" series processors will have two packaging solutions. The smaller StrixPoint will use the FP8 package, while the StrixHalo will use the FP11 package. Source: videocardz source @Olrak29_ The latest revelation is that StrixHalo’s FP11 package size is 37.5mm*45mm (1687 square millimeters), which is the same as the LGA-1700 package size of Intel’s AlderLake and RaptorLake CPUs. AMD’s latest Phoenix APU uses an FP8 packaging solution with a size of 25*40mm, which means that StrixHalo’s F
Detailed explanation of C++ function inheritance: How to debug errors in inheritance?
May 02, 2024 am 09:54 AM
Inheritance error debugging tips: Ensure correct inheritance relationships. Use the debugger to step through the code and examine variable values. Make sure to use the virtual modifier correctly. Examine the inheritance diamond problem caused by hidden inheritance. Check for unimplemented pure virtual functions in abstract classes.
How do inheritance and polymorphism affect class coupling in C++?
Jun 05, 2024 pm 02:33 PM
Inheritance and polymorphism affect the coupling of classes: Inheritance increases coupling because the derived class depends on the base class. Polymorphism reduces coupling because objects can respond to messages in a consistent manner through virtual functions and base class pointers. Best practices include using inheritance sparingly, defining public interfaces, avoiding adding data members to base classes, and decoupling classes through dependency injection. A practical example showing how to use polymorphism and dependency injection to reduce coupling in a bank account application.
The meaning and characteristics of PHP version NTS
Mar 26, 2024 pm 12:39 PM
PHP is a popular open source scripting language that is widely used in web development. NTS in the PHP version is an important concept. This article will introduce the meaning and characteristics of the PHP version NTS and provide specific code examples. 1. What is PHP version NTS? NTS is a variant of the PHP version officially provided by Zend, which is called NotThreadSafe (non-thread safe). Usually PHP versions are divided into two types: TS (ThreadSafe, thread safety) and NTS
