Completely reasonable request, easy to implement along the lines of:
public class Name {
private Name(String name, int flag){...}
public static Name asMissing(){new Name(null, -1);}
public static Name asNotApplicable(){new Name(null, -2);}
public static Name asNotAvailableYet(){new Name(null, -3);}
public static Name asForbidden(){new Name(null, -4);}
public static Name create(String name){new Name(name, 0)}
public boolean isMissing(){flag==-1}
public boolean isNotApplicable(){flag==-2}
public boolean isNotAvailableYet(){flag==-3}
public boolean isForbidden(){flag==-4}
public String get() {if (flag!=0) throw new Exception(flag) else name}
}

I'd prefer enum-like syntactic sugar, something like: public class Name { private Name(String name){...} flags { MISSING, NOT_APPLICABLE, NOT_AVAILABLE_YET, FORBIDDEN } ... } In particular, you shouldn't have to specify a constructor, since these are flag values that don't necessary have any state associated with them.
