带有或不带有参数的Java 6注释重复

Question

I have the following annotation:

public @interface ExcludeVariable {
    String list();
}

I want to be able preprocessing this in two different ways

First:

@ExcludeVariable // without parameter
int a;

Second:

@ExcludeVariable(list="a,b") // with parameter
public void test(){
     int a;
     int b;
     int c;
}

In Java 8 there is an option to "repeat" annotations

http://docs.oracle.com/javase/tutorial/java/annotations/repeating.html

How to handle this in Java 6

Best regards

Use "default". Read more here

public @interface ExcludeVariable {
    String list() default "";
}
