from 2 syntax , b. there performance change , if not put strategy attribute statement.

a)

@generatedvalue(generator = "titlelistmapseq" ,strategy=generationtype.sequence) @sequencegenerator(name = "titlelistmapseq", sequencename = "title_list_map_seq") private long id;

b)

@generatedvalue(generator = "titlelistmapseq") @sequencegenerator(name = "titlelistmapseq", sequencename = "title_list_map_seq") private long id;

both same , if put @sequencegenerator , default calls "strategy=generationtype.sequence".

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
