- 3. Simple Object –oriented Two Stage / Interpreted Platform independent Agenda Platform independent Architecture Neutral Portable Secure Robust Multithreaded Multithreaded Distributed High performance Dynamic www.youtube.com/riseshinekg2pg
- 4. Java is simple programming language Easy to learn even school going students can learn java Syntax is simple based on C++, clean and easy to understand Most of the complex and confusing features / concepts are removed Explicit Pointers, Multiple inheritance removed Auto memory management & Automatic Garbage Collection
- 5. ClassesObject Java is Fully Object-oriented Organize a software as collection of real word entity. Everything in Java is an object. Classes AbstractionPolymorphism Encapsulation / Data hiding Inheritance www.youtube.com/riseshinekg2pg
- 6. Process //Java is Two Stage Programming Language Each java source code is first compiled get converted in byte code and then interpreted and then converted in to machine understandable form Java Source Code .java file Stage 1 Java Compiler Byte Code Class File Stage 2 Java Interpreter 6 www.youtube.com/riseshinekg2pg
- 7. Java is Platform Independent Java is different than any other programming languages which are when get compiled convert source code to particular OS understandable code. Means program executed on one OS can not execute on other machineMeans program executed on one OS can not execute on other machine with out modification. This is not the case with java. Once java program is written it can execute on any machine happily Java Program Write once Run anywhere www.youtube.com/riseshinekg2pg
- 8. Java is Architecture-neutral PIV processor 32 bit 128GB RAM WIN Java Compiler PIV processor 32 bit 128GB RAM WIN I3 processor 500GB RAM Mac OS Java does not depend upon under laying machine I5 processor 128GB RAM MAC OS Java does not depend upon under laying machine architecture. Changes or up-gradation in OS, Processor, system resources does not force any changes in java program www.youtube.com/riseshinekg2pg
- 9. Java is Portal We can migrate java byte code easily from one platform to another platform easily. There is no need to change in java program. www.youtube.com/riseshinekg2pg
- 10. Difference between Java Program Platform Independence Architecture Neutral Portable Write Once Run AnywareWrite Once Run Anyware PIV processor 32 bit 128GB RAM WIN PIV processor 64bit 500GB RAM Linux We can easily migrate java byte code from one machine to another We can easily migrate java byte code from one machine to another Any up-gradation in OS, Processor, RAM or system resources does not affect java program Any up-gradation in OS, Processor, RAM or system resources does not affect java program machine to another machine with different configuration machine to another machine with different configuration
