Basic Java Features

The below mentioned list will explain you the list of java features available. These features are found by comparing java with other technologies/languages. Java has set of advantages/features. Because of these features java becomes more popular than others. Features are,
  1. Simple
  2. Object oriented
  3. Platform independent
  4. Secure
  5. Robust
  6. Architecture Neutral
  7. Portable
  8. Dynamic
  9. Interpreted
  10. High performance
  11. Multi-threaded
  12. Distributed 
Simple:
Java is simple in,
  • Syntax is familiar to C++(So easier to programmer to learn after C++)
  • Removing many confusing or rarely used features. Like Pointers, Structures/Unions, etc.
  • Introducing Garbage Collection.
Object Oriented:
Java is Object Oriented language, means we organised our software as combination of different types of objects. Object Oriented Programming (Oops) is a methodology that simplifies software development and maintenance by providing some rules. Basic Oops concepts are,
  • Object
  • Class
  • Inheritance
  • Polymorphism
  • Abstraction
  • Encapsulation
Platform Independence:
Platform is nothing but a software or Hardware environment in which a program runs. Platform is two types are there, software base and hardware based platform.
Platform independence is nothing but we are developing our java files in one machine (Windows) and running that same source code in another machine (Unix or Linux...). This is also called as "WORA"(Write Once Run Anywhere).

Secured:
  • No explicit pointer
  • Program runs inside virtual machine.
That means when your running your C++ program that runs inside the Operating System. Every java program is executed under the Java Virtual Machine. That means every java installation have their private Run-time environment. Java provides some security, but programmer also provides security by using the JAAS, Cryptography, etc.

Robust:
Robust simply means Strong. Java provides strong memory management. There are number of pointers that are avoiding for reducing security problems.

Architecture Neutral:
  • Compiler generates byte-codes, which have nothing to do with particular computer architecture.
  • Easy to interpret on any machine.
Portable:
We may carry to java byte-code to any platform, means transferring java code from one platform to another platform is easy.

High performance:
Java as faster than traditional interpretation since byte-code is "close" to native code still somewhat slower than a compiled language. Like C or C++...

Distributed:
  • It has a spring-like transparent RPC system
  • Now used mostly TCP/IP based protocols like HTTP & FTP.
Multi-threaded:
A thread is like a separate program, executing concurrently. We can write java programs that can deals many tasks at once by defining multiple threads. The main use of multi-threading is shares same memory.

JVM, JRE and JDK in Java

JVM, JRE and JDK are the most basic common concepts to know in java. These are the basic features to understand how Java architecture works? JVM stands for Java Virtual Machine, which doesn't have any physical directories created in java installation. JRE stands for Java Runtime Environment, which creates the directory under Java installation path and also present in JDK. JDK stands for Java Development Kit, which creates the directory in Java installation path and also it has it's own JRE. Since we have already learn that Java is platform independent means if we have implemented any of the java class in one environment, it will be executed in any other environment and provides the same output. But, JVM, JRE and JDK all are platform dependent . So that, for windows, linux, unix, mac, solaris..etc has it's own JVM, JRE and JDK. One will be not compatible with other environments. While installing the Java, we might come to know a bit about JRE and JDK. But, JVM is the other...

Prime, Fibonacci and Factorial number with example in java

Prime number, Fibonacci series and Factorial number programs are most commonly asked questions in interview. Read this article to know what is and how to write programs for prime number, fibonacci series and factorial number. Prime Number: prime number is natural number greater than 1 that has no positive divisor other than 1 and itself. A natural number greater than 1 is not a prime number, is called Composite number . For example, 7 is a prime number. Because it can divide with 1 and 7 only. Where as 8 is composite number. Since it has the divisor 2 and 4 in addition to the 1 and 8. The below example represents the finding the passing number is prime number or not. If the passing number is prime number it will print true otherwise it will print false. package com . javatbrains . practice ; public class PrimeNumber { public boolean isPrimeNumber ( int number ) { if ( number <= 1 ) return false ; // There's only one ...

How to insert images into database using JDBC?

How to insert images into database table by using JDBC? To know about these topic follow the below lines,           Before going to write a JDBC program for inserting images into database table, we need to create a specific table for inserting images column datatype. For creating the database table, execute the below command in MySQL command prompt. 1 2 3 4 CREATE TABLE ` images ` ( ` image_id ` int ( 11 ) NOT NULL AUTO_INCREMENT, ` image_flag ` int ( 11 ) NOT NULL , ` image ` longblob NOT NULL , PRIMARY KEY ( ` image_id ` ));           After executing the above query in MySQL command prompt, execute the below query to know weather the above table query is created or not. 1 Show tables;            When you have executed the above query that will show you the list of table which all exists in the current database. Current tab...
