3. Introduction:  Programming Language Paradigms  Environment of Java

4. Programming Language Paradigms A programming paradigm is a fundamental style of computer programming. This means the manner or approach used in the programming. Based on programming paradigms, programming languages are broadly classified into two levels: low-level languages and high-level languages. High-level languages are classified into four programming paradigms: imperative, functional, declarative and object-oriented. [1], [2] Introduction …

5. Programming Language Paradigms Introduction … Low-level languages Machine language Programming languages High-level languages Assembly language Imperative languages Object-oriented languages Declarative languagesFunctional languages (First-generation language) (Second-generation language) (Third-generation languages) (Fourth-generation languages)

6. Programming Language Paradigms Introduction … There are several key concepts in object-oriented programming (OOP): Data Abstraction Encapsulation Inheritance Polymorphism [3]

7. Environment of Java Introduction … Java development environment is used to edit, compile and execute java applications If there are no errors If there are errors Program output Compile program Edit program Execute program

8. Environment of Java Introduction … The overall process of the typical Java development environment: [4] If there are errors Sample.java Sample.class Executed by Compiled by Editor generates Java Compiler Java source code file Java bytecode executable file JVM If there are no errors

10. What Java Can Do? What Java Can Do? [4],[5]  Java is platform-independent  Java is Portable (WORA)  Java is Object-Oriented  Java is Interpreted  Java is Robust  Java is Distributed  Java is Secure  Java is Multithreaded  Java is Dynamic Why Java …

11. What Java Cannot Do? What Java Cannot Do? [6] Java can't convert an int to a boolean value, Java has no 8-bit unsigned byte, Java has no first class methods, Java has no pass by reference semantics, Burn a CD/DVD, Copy or move a file (with all metadata intact), Raw console access; e.g. curses, clear screen, etc. In general it lacks in low-level programming (not designed to write OS, compilers, etc.) Why Java …
