[ajug-members] design theory

[mcdaniel]

can someone tell me what design to an interface means- what i mean by 
this is that i know what it means by definition- because i read about it 
often- most oop examples are oak tree extends tree, implements growable, 
and then tree extends plantae... etc -then i see lots of  code right up 
front as extends jframe, extends awprx.border etc; so...  and this may 
be basic'ish, but what's a persons' example of design to the 
interface(s); by the way- i am enjoying learning java (i've programmed 
for years, but it has all been procedural) and tks for any (theory)input 
[i think that i just casted theory-traits onto what was an 'input' object]
