java - generic return object -

recently reading next piece of code oracle collection tutorial when came across piece of code.

public static <e> set<e> removedups(collection<e> c) { homecoming new linkedhashset<e>(c); }

i not able understand why returned value

<e> set<e> , not set<e> ?

the homecoming type is, in fact, set<e>.

the other <e> there indicate generic method, , state e parameter generic. without <e>, compiler assume e existing class, , seek locate (producing error if no class named e in scope).

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...
