In Java, hardcoding (Hardcoding) refers to using specific values, strings, or other constant values directly in the code, rather than obtaining these values through external configuration files or variables.
Example hardcoded to start:
javaCopy code
public class ExampleClass { public static void main(String[] args) { String serverHost = "192.168.0.100"; int serverPort = 8080; // 使用硬编码的主机和端口 connectToServer(serverHost, serverPort); } private static void connectToServer(String host, int port) { // 连接到服务器的逻辑 // 使用传入的主机和端口参数进行连接 } }
In the above example, the hardcoded approach writes the server host and port directly into the code as strings and integers. This means that the source code needs to be modified and recompiled every time the server host or port needs to be changed. Such a design lacks flexibility and may lead to difficulties in maintenance and configuration.
In contrast, placing these values in configuration files or through external configuration methods such as command-line parameters can provide better flexibility and maintainability. For example, define the server host and port using a properties file or environment variable, and read these values from the configuration file or environment variable at program startup.
Summary: Boot hardcoding is the practice of using specific numeric or constant values directly in your code. Its disadvantage is that it lacks flexibility, making configuration and maintenance difficult. In contrast, using external configuration files or variables to obtain these values provides better configurability and maintainability.
