java - Passing a class constant in param -

i've little problem in java. think i'm not still awake.

i have 2 classes:

the first 1 use constants jar (example : highgui.cv_load_image_color). in second 1 user select in list constant want use.

so, second class call method of first one, "stringify" constant use in param.

but first 1 can't use string in param has real class constant.

i know, that's stupid problem, i'm pretty sure i'm missing obvious.

someone have idea deal that?

edit :

a piece of code more clarity :

in class2

class1.finder("c:aaa.jpg","highgui.cv_load_image_color"); 

in class1

public void finder(string path1, string constant){     mat object = highgui.imread(path1, highgui.cv_load_image_color);     //i want use "constant" instead of highgui.cv_load_image_color } 

this looks design problem. passing strings around, containing name of java constant, not idea. why don't create class, or enum, containing value of color , description:

public enum describedcolor {     cv_load_image_color("cv load image color", "red"),     ...      private string description;     private string color;      private describedcolor(string description, string color) {         this.description = description;         this.color = color;     } } 

then in class1 :

public void finder(string path1, describedcolor describedcolor) {     ... } 

and in class2 :

class1.finder("c:aaa.jpg", describedcolor.cv_load_image_color); 

and in list displayed user, need store describedcolor instances, , use description value displayed user.

this way, you're oo, type-safe, self-documenting, , don't need nasty reflection tricks.
