#100 a declaration here must declare a parameter

这是一个语法错误，它通常出现在函数或方法定义中，表示你忘记了声明一个参数的类型和名称。例如：

void myFunction() {
    // code here
}

应该改为：

void myFunction(int myParameter) {
    // code here
}

其中，`int myParameter` 就是声明了一个类型为 `int`，名称为 `myParameter` 的参数。这样就避免了语法错误。

Which one of the following annotation is used to load application. properties file in the REST web application? A.@PropertiesResource B.@PropertiesSource C.@PropertySource D.@propertyResource

The correct annotation to load application.properties file in a REST web application is C. `@PropertySource`.

`@PropertySource` is a Spring Framework annotation that is used to declare a `PropertySource` to be used by the `Environment`. This annotation can be used at the class level or the method level. When used at the class level, it can be used to load properties from a properties file, a YAML file, or a Java properties object.

For example, to load the `application.properties` file in a Spring Boot application, you can use the `@PropertySource` annotation as follows:

@Configuration
@PropertySource("classpath:application.properties")
public class AppConfig {
    // ...
}

This will load the `application.properties` file from the classpath and make it available to the `Environment` for use in the application.
