DataBase Applications with JDBC
Connect to and perform database SQL operations, process query results using JDBC API
Java Object Oriented Approach
create and use enumerations
Create and us interfaces, identify functional interfaces , and utilize private , static and default methods
Utilize polymorphism and casting to call methods, differentiate object type versus reference type
Create and use subclasses and superclasses , including abstract classes
Understand variable scopes, apply encapsulation and make objects immutable
Ininisialize objects and there members using instance and static initialiser statements and constructors.(remember forward referencing)
Define and use fields and methods, include instance,static and overloaded methods
Explain object's lifecycle(including creation , dereferencing by reassignlent, and garbage collection)
Declare and instantiate Java objects including nested class objects
Java Platform Module System
Declare , use and expose modules , including the use of services
Deploy and execute modular applications , including automatique modules
