java-reflection affects efficiency
The reflection of the java-code will affect the execution efficiency. The reasons were as follows: 1. ** Restrictions on the optimization of the compile **: The JIT compile will perform optimization according to the running condition of the program to improve the efficiency. However, the JIT compile cannot determine the specific method of the reflection call during compilation, and the JIT compile cannot perform static analysis and optimization on it, thus reducing the performance of the reflection. 2. ** Automatic Unboxing Operation **: In reflection, since the compilation process does not know the specific parameters of the method, the most common reference type, Object, is needed to handle all the parameters. This caused the JVs to perform automatic unboxing operations at run-time, converting the Object type into the actual argument type, which added additional overhead. 3. ** Method call overhead **: Reflection will traverse the method array when calling a method, but normal method calls do not need this traverse operation, which will increase the time overhead of reflection calls. 4. ** Security check **: Reflection operation has a certain performance overhead and potential security issues. However, you can skip the security check (you can read the private property) by using setEasily (true) to increase the program's running efficiency by four times. In summary, although reflection provided powerful capabilities for developers, in scenarios with high performance requirements, the reflection mechanism should be used with caution to avoid unnecessary performance loss. Whenever possible, use static type checking and direct method calls to improve the execution efficiency of the program. Read more exciting novels for free
