First algorithm class we met a guest lecturer Mr.Feri he taught us about OOP. OOP is Object Oriented Programming it’s divided to 5 type, Inheritance , Interface , Polymorphism , Abstraction , and Encapsulation.
First Inheritance it behaves not compulsory
second Interface it behaves compulsory but can copy one or more
third Polymorphism is overwriting old method and renew it with the newer and more efficient method
fourth abstraction behaves compulsory
fifth Encapsulation it behaves private and only authorized person can see it.
we also learned the same thing that we already learned in AO, like History of Algorithm, Flowchart, Pseudocode , C language and many more, it’s exactly like we learned at AO so i guess the only new thing that i learned is OOP.
After that he told us about his experience about Indonesia weak cyber security , with his idea being rejected about cyber army. After Australia hijack Indonesia Incident, The government felt regret and decide to call him again and now we are building our own cyber army.
