Before we Start our main topic lets get a overview: What is a Programming Language? Definition: A programming language is a special language used to write instructions that a computer can understand and follow. Just like we use English or Hindi to talk to each other, programmers use languages like Java, Python, or C++ to talk to computers. Why do we need it? Computers are dumb without instructions. A programming language helps us: Tell the computer what to do Solve problems Make websites, games, apps, software, etc. Types of Programming Languages: Low-level languages Closer to machine language (0s and 1s) Example: Assembly Language High-level languages Easier to read and write Example: Java, Python, C++, JavaScript Example: Let’s say we want to add two numbers . In Java, you can write: int a = 5 ; int b = 10 ; int sum = a + b; System.out.println(sum); This tells the computer: “Hey! Add 5 and 10, and show me the ...
SYLLABUS 1. Introduction to Object Oriented Programming concepts: (i) Principles of Object Oriented Programming, (Difference between Procedure Oriented and Object-oriented). All four principles of Object Oriented Programming should be defined and explained using real-life examples (Data abstraction, Inheritance, Polymorphism, Encapsulation). (ii) Introduction to JAVA - Types of Java programs – Applets and Applications, Java Compilation process, Java Source code, Byte code, Object code, Java Virtual Machine (JVM), Features of JAVA. Definition of Java applets and Java applications with examples, steps involved in the compilation process, definitions of source code, byte code, object code, JVM, features of JAVA - Simple, Robust, secured, object-oriented, platform-independent, etc.
