Java如何注解类或方法？
本示例说明如何HelloAnnotation在前面的示例代码“如何创建简单的注释？”上使用注释。我们将HelloAnnotation注释添加到我们的类及其方法中。
package org.nhooo.example.lang.annotation;
@HelloAnnotation(value = "Good Morning", greetTo = "Universe")
public class HelloAnnotationExample {
public static void main(String[] args) {
HelloAnnotationExample anno = new HelloAnnotationExample();
anno.sayHi();
anno.sayHello();
}
@HelloAnnotation(value = "Hi there", greetTo = "Alice")
private void sayHi() {
}
@HelloAnnotation(value = "Hello there", greetTo = "Bob")
private void sayHello() {
}
}
