Hi David OOP is far too complicated.
I represent your data by a sorted file like this 0 animal 01 bird 02 reptile 021 snake 022 newt 023 frog 03 mammal 031 deer 032 rabbit 033 squirrel 034 skunk 1 counts 123 1 134 1 Note that digit zero in the line number is a wildcard character. Zero padding to the right is allowed. Choosing a data structure is independent on choosing a programming language. -Bo --- Den tors 18/3/10 skrev David Ward Lambert <[email protected]>: Fra: David Ward Lambert <[email protected]> Emne: [Jprogramming] OOP in j Til: [email protected] Dato: torsdag 18. marts 2010 21.17 When I run my dog I count critters. I can identify some of them. And so developed a taxonomy counter in python. Incrementing one of these objects also increments all those above it. Thus if we find a frog I'd increment the animal object; on finding a skunk we'd go elsewhere before incrementing "mammal". Home again I'd read 2 animal, 1 mammal, 0 all else. I suppose I used a registration technique in the python object initializer. Solutions in j please? The interface includes construct structure, modify any of the objects, report correctly. animal bird reptile mammal / \ / | \ snake newt deer rabbit squirrel Related, has anyone written Design Patterns in j? Thanks, Dave. __________________________________________________ Bruger du Yahoo!? Er du træt af spam?
