Multi-layered Hash in Java -

Multi-layered Hash in Java -

in perl if want have multi-layered hash, write:

$hash_ref->{'key1'}->{'key2'}='value';

where 'key1' might person's name, 'key2' might "savings account" (vs. "checking account") , 'value' might amount of money in account.

is there equivalent in java, i.e. access values via hash references? what's syntax this? examples or other resource references appreciated. thanks!

you can have map<map<..>>, you'll able phone call map.get("key1").get("key2")

but note java statically-typed, object-oriented language. you'd improve creat classes: person, savingsaccount, , person has field private savingsaccount savingsacount. you'll able compile-time safe: map.get("john").getsavingsaccount()

java hash reference multi-level multi-layer

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
