How to add a client-side Database for devs

package bdb.demo;
import balloondb.DataObject;
/* BalloonDB only accepts DataObjects to ensure
   that the class is serializable and have other
   necessary features such as a key.
*/
public class CustomObject extends DataObject {
    String name;
    double id;
    public CustomObject(String name, double id) {
        this.name = name;
        this.id = id;
    }
}

CustomObject obj1 = new CustomObject("Some-name", 15.2D);
CustomObject obj2 = new CustomObject("Diff-name", 45D);
BalloonDB bdb = new BalloonDB(new File("/Test")); 
bdb.insert(obj1);
bdb.insert(obj2);
bdb.forceSave();
bdb.select("CustomObject where name = \"Some-name\"");
bdb.delete("CustomObject where id = 45");

The physical file will be save in /Test followed by the class path, in this case /bdb/demo, and the file name with by an auto-generated UUID. So it will under /Test/bdb/demo/{some UUID}.ser
