How to Design A Map Class

Question

Hi Folks
I am trying to design a utility class for my Application.
I am having many tables for Id and description
Eg CustomerId CustomerDescription
AccountId AccountDesc
Presntly I am Writing a Class in which there is a method which Returns MAP ID vs Descition for Individual.
But I want to design a class which should have only one Method and depepending upon the Query It should Return The Map of Corresponding Table.
Help Is deeply Appreacited

THx for your answer..
It's my first inherit sample code:
* baseClass.java
package inherit_test;
* @author
public class baseClass {
    /** Creates a new instance of baseClass */
    public baseClass() {
   public void doSomethingWickedAwesomeCOOL(){
      System.out.println("Isn\'t this wicked Awsome COOL!?!");
* extendingClass.java
package inherit_test;
* @author
public class extendingClass extends baseClass{
    /** Creates a new instance of extendingClass */
    public extendingClass() {
    public void doSomethingWickedAwesomeCOOL() {
      System.out.println("This SUCKS!");
* Main.java
package javaapplication1;
* @author
import inherit_test.*;
public class Main {
    /** Creates a new instance of Main */
    public static void inherit_Main(baseClass base) {
        base.doSomethingWickedAwesomeCOOL();
     * @param args the command line arguments
    public static void main(String[] args) {
        // TODO code application logic here
        baseClass base=new baseClass();
        extendingClass extending=new extendingClass();
        inherit_Main(base);
        inherit_Main(extending);
}It's running result:
Isn't this wicked Awsome COOL!?!
This SUCKS!
