Features of Java

Java Programming


Simple:

          Learning and practicing java is easy because of resemblance with c and C++. 

Object Oriented Programming Language:

                                                                                    Unlike C++, Java is purely OOP. 

Distributed: Java is designed for use on network;

                                                      it has an extensive library which works in agreement with TCP/IP. 

Secure: 

           Java  is  designed  for  use  on  Internet.  Java enables the construction  of  virus free, tamper free systems. Using Java Compatible Browser, anyone can safely download Java applets without the fear of viral infection or malicious intent. Java achieves this protection by confining a Java program to the Java execution environment and by making it inaccessible to other parts of the computer. We can download applets with confidence that no harm will be done and no security will be breached.

 Interpreted:

                  Java programs are compiled  to generate  the byte code. This byte code can be downloaded and interpreted by the interpreter. .class file will have byte code instructions and JVM which contains an interpreter will execute the byte code.    

Portable:

              In Java, many types of computers and operating system are in use throughout the world and are connected to the Internet. For downloading programs through different platforms connected to the Internet, some portable, executable code is needed. Java does not have implementation dependent aspects and it yields or gives same result on any machine. 


Multithreaded:

                            Executing different parts of program simultaneously is called multithreading. This is an essential feature to design server side programs.  


High Performance:

                             Along with interpreter there will be JIT (Just In Time) compiler which enhances the speed of execution.

Byte Code:

Java Programming Byte Code: It is the unique characteristic property of the Java programming language. It is something like a normal text file. Therefore, it cannot be affected by virus. It is an intermediate between a human readable source and machine readable source. Byte codes are plate form independent. Therefore, JVM is plate form dependent to make Java programming plate form indepdent.  

Difference between Class and Interface

Java Programming   *Difference between Class and Interface                                                  Class 1.  The members of a class can be constant or variables.  2. The class definition can contain code for each of its methods. That is, the methods can be    abstract or non-abstract. 3. It can be instantiated by declaring objects. 4. It can use various access specifier like public,private or protected.                                                Interface     1. The members of an interface are always declared as constant, i.e. their values are final.  2. The methods in an interface are abstract in nature, i.e., there is no code associated with  ...

OPERATING SYSTEM

1.  The term 'operating system'   means: a)  the way a computer operator   works. b)  conversion of high level languages into machine   code. c)  a set of programs which controls computer   working. d)  none of the   above. 2.  What is the name of the operating system that reads and reacts in terms of actual   time: a)   Batch   system b) Time sharing system c) Real   time   system d) all of the above. 3.  The primary job of the operating system of a computer is   to: a)   command   resources b) manage   resources c) be   user friendly d) only one of the   above. 4.  Multiprogramming   systems: a) are easier to develop than single programming systems. b) execute more jobs in same time period. c) are used only on large   mainframe   computers. d) all of the above 5.  Which of the following is not an a...
