In above example, imported classes are SQLException and Connection. These both belong to java.sql package of JDBC API. Here is an example code that uses data received using the Java JDBC API: public static void commit() { Connection chk_con = this.get(); if (chk_con != null) {...
A nice way to get the most out of these examples, in my opinion, is to read them in sequential order, and for every example:Carefully read the initial code for setting up the example. If you're an experienced Python programmer, you'll successfully anticipate what's going to happen next...
Note that when calling instance methods on an object,selfis not used! Example: classPerson:def__init__(self,name,age):self.name=nameself.age=agedeffetch_name(self):returnself.namedeffetch_age(self):returnself.agedefset_age(self,age):self.age=agep=Person("Ross",30)print(p.fetch_name...
