#Oop Concept

OOP Follow @lky_112l 👨‍💻 ..... في اليابان، يتم استخدام البلاطات الكهروضغطية (piezoelectric tiles) لتحويل حركة المشي إلى كهرباء. هذه البلاطات تلتقط الطاقة الحركية الناتجة أثناء المشي. عندما يمشي شخص فوقها، يتسبب وزنه في انضغاط طفيف في البلاطة، مما يولد ضغطًا ميكانيكيًا (mechanical stress). المادة الكهروضغطية داخل البلاطة تحول هذا الضغط إلى كهرباء. كل خطوة تولد كمية صغيرة من الشحنة الكهربائية (electric charge)، ومع ملايين الخطوات يتم إنتاج كمية كافية من الكهرباء لتشغيل مصابيح LED. في أماكن مثل محطات شيبويا، يساهم حوالي 2.4 مليون خطوة يوميًا في هذا النظام. يمكن تخزين هذه الكهرباء أو استخدامها مباشرة، مما يقلل الاعتماد على مصادر الطاقة التقليدية.

Here are clear, simple, point-wise explanations of Encapsulation you can directly use: •Encapsulation is an OOP concept. •It wraps data (variables) and methods into a single unit called a class. •Data is hidden from direct access. •Access to data is controlled using methods. •Helps protect data from misuse. •Improves code security. •Makes code easier to manage and maintain. •Achieved using private variables and public methods. #java #javaroadmap #oopsconcepts #javaprogramming #encapsulation

Polymorphism is an OOP concept. •It means one action can have many forms. •The same method name can behave differently. •It allows methods to perform different tasks based on the object. •Polymorphism improves flexibility in code. •Helps in writing reusable and scalable programs. •There are two types of polymorphism in Java: •Compile-time (method overloading) •Runtime (method overriding) •Polymorphism makes code easier to extend and maintain. #java #learnjava #codinglife #oopsconcepts #polymorphism
