Java中静态代码块中字段初始化的正确方法

public class MyClass {
    private static int count;
    private static String message;

    static {
        count = 10;
        message = "Hello, World!";
    }
}

public class Constants {
    public static final int MAX_SIZE;

    static {
        MAX_SIZE = 100;
    }
}

public class ResourceManager {
    private static Map<String, Object> resourceMap;

    static {
        resourceMap = new HashMap<>();
        // 加载资源文件到resourceMap中
    }

    public static Object getResource(String name) {
        return resourceMap.get(name);
    }
}
