Java OOP Mini Project in Hindi | Bank Management System | Java Course #25

☕ Java OOP Mini Project in Hindi | Bank Management System | Java Course #25 Java Programming for Beginners in Hindi के Episode #25 में हम Java OOP के concepts को सिर्फ theory में नहीं, बल्कि एक practical Bank Management System Mini Project बनाकर समझेंगे। इस project में हम Classes & Objects से लेकर Encapsulation, Inheritance, Polymorphism, Abstraction और Interface तक के concepts को एक ही Java program में combine करेंगे। 🔥 इस वीडियो में आप सीखेंगे: ✅ Java OOP Mini Project कैसे बनाएं ✅ Bank Management System Project ✅ Class & Object का practical use ✅ Constructor और this Keyword ✅ Encapsulation using private fields ✅ Getters का practical use ✅ Deposit & Withdraw Methods ✅ Input Validation ✅ Abstract Class ✅ Abstract Method ✅ Interface और implements ✅ Inheritance using extends ✅ Method Overriding ✅ Runtime Polymorphism ✅ Parent Reference + Child Object ✅ super() का basic use ✅ SavingsAccount और CurrentAccount ✅ Multiple OOP Concepts को एक Project में कैसे combine करें 🏦 Project Structure Printable Interface | ↓ BankAccount Abstract Class / \ / \ SavingsAccount CurrentAccount हमारा BankAccount एक Abstract Parent Class होगा: abstract class BankAccount implements Printable { private String accountHolder; private int accountNumber; private double balance; abstract void calculateInterest(); } यहाँ एक साथ कई concepts use हो रहे हैं: private → Encapsulation abstract → Abstraction implements → Interface इसके बाद: class SavingsAccount extends BankAccount और: class CurrentAccount extends BankAccount बनाकर Inheritance और Method Overriding practically implement करेंगे। 🔥 Runtime Polymorphism Project में हम यह भी use करेंगे: BankAccount account; account = new SavingsAccount( "Rahul", 1001, 10000 ); account.calculateInterest(); account = new CurrentAccount( "Priya", 1002, 20000 ); account.calculateInterest(); एक ही Parent Reference अलग-अलग Child Objects को refer कर रहा है और overridden method actual object के अनुसार execute हो रहा है। यही है: 🔥 Runtime Polymorphism 🧠 इस एक Project में OOP Revision Class & Object Constructor this Keyword Encapsulation Inheritance Method Overriding Polymorphism Abstraction Abstract Class & Method Interface implements super() इसलिए अगर आपने हमारी पिछली Java OOP classes देखी हैं, तो यह project आपके लिए एक complete OOP Practical Revision भी होगा। 🎯 Assignment एक नया Account Type बनाइए: class SalaryAccount extends BankAccount Requirements: Constructor बनाइए Parent Constructor call कीजिए calculateInterest() Override कीजिए SalaryAccount Object बनाइए Deposit कीजिए Withdraw कीजिए Account Details Display कीजिए 🔥 Bonus Challenge: Polymorphism use करें: BankAccount account = new SalaryAccount(...); Assignment complete होने के बाद comment करें: 🔥 OOP Mini Project Completed ✅ 📚 JAVA OOP JOURNEY ✅ Classes & Objects ✅ Constructors ✅ this Keyword ✅ Encapsulation ✅ Inheritance ✅ Method Overriding ✅ Polymorphism ✅ Abstraction ✅ Interface 🔥 OOP Mini Project — Bank Management System 🎬 NEXT CLASS #26: super Keyword in Java हम सीखेंगे: super() super.variable super.method() Parent Constructor Parent & Child Constructor Execution this vs super 👍 Video को LIKE करें 💬 Assignment complete करके COMMENT करें 📤 दोस्तों के साथ SHARE करें 🔔 Coding Center को SUBSCRIBE करें Coding Center Learn • Practice • Grow ☕ Java | Programming | Technology #Java #JavaOOP #JavaProject #JavaMiniProject #BankManagementSystem #OOPProject #JavaInHindi #JavaForBeginners #JavaTutorial #JavaProgramming #CoreJava #OOP #LearnJava #CodingCenter #JavaCourse #Programming java oop mini project java oop mini project in hindi java project for beginners java project for beginners in hindi bank management system in java bank management system java project bank management system project in java bank management system in java for beginners java bank management system java bank account project java banking project oop project in java oop project in java in hindi java oop practical project java oop practical example java oop concepts with project java oop concepts in hindi java mini project in hindi java mini project for beginners java console project for beginners class and object project java encapsulation project in java inheritance project in java polymorphism project in java runtime polymorphism java example abstraction project in java abstract class project java interface project in java java inheritance polymorphism project java abstract class interface project bank account program in java deposit withdraw program in java java programming project core java project core java project in hindi java tutorial in hindi java course in hindi coding center java
