Stopping repetition in Java enums

Question

I have the following enum in a Java class:

public enum Resolution {
    RES_32 (32),
    RES_64 (64);
    private final int asInt;
    private R

The following lets you work with enums on runtime, this is the reference link http://www.theserverside.com/news/thread.tss?thread_id=50190:

Constructor con = Day.class.getDeclaredConstructors()[0]; 
Method[] methods = con.getClass().getDeclaredMethods(); 
for (Method m : methods) 
{ 
    if (m.getName().equals("acquireConstructorAccessor")) 
    { 
        m.setAccessible(true); 
        m.invoke(con, new Object[0]); 
    } 
}

Field[] fields = con.getClass().getDeclaredFields(); 
Object ca = null; 
for (Field f : fields) 
{ 
    if (f.getName().equals("constructorAccessor")) 
    { 
        f.setAccessible(true); 
        ca = f.get(con); 
    } 
}

Method m = ca.getClass().getMethod( "newInstance", new Class[] { Object[].class }); 
m.setAccessible(true); 
Day v = (Day) m.invoke(ca, new Object[] { new Object[] { "VACATION", Integer.MAX_VALUE } }); 
System.out.println(v.getClass() + ":" + v.name() + ":" + v.ordinal());
