How can we access type and subtypes of enum in java? -

i need implement following using enum.

import java.util.*;  /**  *  * @author mukesh  */ public class mytest { private list<subtypes> subtypes = new arraylist<subtypes>();     enum types {         percentarea, stackedarea, chartsubtype3;     }      enum subtypes {         persentarea1(types.percentarea),         persentarea2(types.percentarea),         persentarea3(types.percentarea),         stackarea1(types.stackedarea),         stackarea2(types.stackedarea),         stackarea3(types.stackedarea);                     types t;         private subtypes(types t) {                             this.t = t;             }         }          public list<subtypes> getsubtypes() {             return collections.unmodifiablelist(subtypes);         }          public static void main(string[] args) {                        /* how can subtypes based on base type ??? */     }} 

example :

suppose in 1 combo have types - percentarea, stackedarea, chartsubtype3 etc. , if select percentarea second combo can sub types e.g. persentarea1, persentarea2 etc.

can 1 guide me how can retrieve values of subtype given types.

i think need this

private static void getsubtypes(types type) {     subtypes[] values = subtypes.values();     for(subtypes value : values)     {         if(value.t == type){             system.out.println("found subtype "+ value);         }     }  } 

hope helps!

good luck!
