Spring MVC Validation - FAQ: Is it possible to integrate multiple validation string in one annotation?

CourseCode.java

@Constraint(validatedBy = CourseCodeConstraintValidator.class)
@Target( { ElementType.METHOD, ElementType.FIELD } )
@Retention(RetentionPolicy.RUNTIME)
public @interface CourseCode {

	// define default course code
	public String[] value() default {"LUV"};
	
	// define default error message
	public String message() default "must start with LUV";
	
	// define default groups
	public Class<?>[] groups() default {};
	
	// define default payloads

			// loop thru course prefixes
			//
			// check to see if code matches any of the course prefixes
