The relationship between embedded systems and Java is gradually evolving under the influence of technological development and market demand, but it has not yet reached the stage of complete replacement. I have collected and classified an embedded learning package, which is really great for novices. It includes programming teaching for novices at different stages of learning, video explanation of problems, 800 sets of graduation projects and language teaching. You can get it for free by typing 22.

Here are some key points: Java's use in embedded systems: Java ME (Micro Edition): Java ME was once one of the widely used platforms in embedded systems, suitable for resource-constrained devices and application scenarios. It provides a high-level abstract programming environment that enables developers to develop applications across platforms. Java SE Embedded: The embedded version of Java SE is also used in some embedded devices that require higher performance or more functions.

Diversity of embedded systems: The application range of embedded systems is very wide, ranging from microcontrollers to embedded Linux systems and real-time operating systems (RTOS) and other different types of devices. Therefore, the selection of the appropriate programming language and platform depends on the specific device characteristics, power consumption, performance requirements and developer skills. Factors affecting language selection: Real-time requirements: For embedded systems that require high real-time performance, C/C++ or specialized hardware description languages ​​(such as Verilog, VHDL) are usually selected.

Resource limitations: Some low-end devices may not be able to support the Java runtime environment, so it is more appropriate to choose a more lightweight language and platform. Development and maintenance costs: Java provides advanced development and management tools that can reduce development cycles and maintenance costs, but it also increases runtime resource consumption and complexity.

In summary, although Java is used in some embedded systems, it will not completely replace traditional low-level languages ​​such as C/C++. When choosing a programming language, you need to consider the specific application requirements, device characteristics, and the technical background of the development team in order to make the most appropriate decision.
