HISTORY OF JAVA AND DOWNLOAD(PDF)

what is java:
            java is a object oriented,platform independent programming language from sun micro system which is released into the marked on the name of development of the distributed applications.

what is java slogan:
                      "Write Once Run Anywhere "(WORA)
java is a platform independent programming language.it means that program is written once and the program is executed irrespective of the operating system.

why java is suitable for internet:
     security problems on internet are eliminated through java.java is a system independent,java is executable on any platform
note:know the what is platform and what platform independent click

JAVA HISTORY:
  IN 1990,sun microsystems inc., USA is developed software for remotes..in 1993,oak language is developed,by that time some company is registered oak name,for this reason they named as "java".
in 1995,sun world conference has given entire details of java.

Oracle database 11g software download

Oracle Database 11g Express Edition


Free to develop, deploy, and distribute


Oracle Database 11g Express Edition (Oracle Database XE) is an entry-level, small-footprint database based on the Oracle Database 11g Release 2 code base.  It's free to develop, deploy, and distribute; fast to download; and simple to administer.
Oracle Database XE is a great starter database for:
  • Developers working on PHP, Java, .NET, XML, and Open Source applications
  • DBAs who need a free, starter database for training and deployment
  • Independent Software Vendors (ISVs) and hardware vendors who want a starter database to distribute free of charge
  • Educational institutions and students who need a free database for their curriculum
With Oracle Database XE, you can now develop and deploy applications with a powerful, proven, industry-leading infrastructure, and then upgrade when necessary without costly and complex migrations.
Oracle Database XE can be installed on any size host machine with any number of CPUs (one database per machine), but XE will store up to 11GB of user data, use up to 1GB of memory, and use one CPU on the host machine.

JAVA EDITIONS AND WHAT IS JDK AND JRE

Sun micro systems provides ,with the advent of java,new versions had multiple configurations built for different types of platforms.those are
  • JSE
  • JEE
  • JME.
JSE:java platform,standard edition:
JSE stands for java platform,standard edition,it is specification used to develop fundamental
java application they may be standard or network.

JEE:java platform,enterprise edition:

 JEE stands for java platform, enterprise edition,it is specification used to develop business
solutions for network (or)JEE is specification that provides an environment to run the web components and the enterprise components.

 JME:java platform,micro edition:
JEE stands for java platform, micro edition,it is specification used for developing wireless and
embedded system.embedded system is software,which directly installed into hardware.
java software:
             java software is cotegorized in to two types
                JAVA=JDK+JRE

                                    


JDK:
           it stands for java development kit
JRE:
          it stands for java runtime environment 
          JRE=JVM+JAVA LIBRARY

if java programs have to run we required the jvm and java library.jvm will starts execution of java
program from main method only.
  • in java every statement must end with semi colon(;).
  • java is case sensitive programming language.

WEKA 3.7.9 SOFTWARE DIRECT DOWNLOAD



Weka is a collection of machine learning algorithms for data mining tasks. The algorithms can either be applied directly to a dataset or called from your own Java code. Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualization. It is also well-suited for developing new machine learning schemes.
Found only on the islands of New Zealand, the Weka is a flightless bird with an inquisitive nature. The name is pronounced like this, and the bird sounds like this.
Weka is open source software issued under the GNU General Public License.

HOW TO REPRESENT NUMBER SYSTEMS IN PROGRAMMING LANGUAGE???

In this real world we have 4 types of number systems they are:
1.binary number system           [format:0,1]
2.octal number system             [format:0,1----7]
3.decimal number system        [format:0,1-----9]
4.hexa decimal system             [format:0,1---9,a,b,c,d,e,f ] 
genarally we use the decimal number system in any programming language.

  In java we can represent the binary values by giving ob infront of the number
ex: int ob10;(correct)
     int x=o4235;(wrong)

representation of the binary number feature is introduced in java 1.7


we can represent the octal values in java programming language by giving o infront of the number
ex: int i=o24;(correct)
        int k=o248;(wrong)[because octal range 0-7]

we can represent the hexa decimal values in java programming language by giving ox infront of the number
ex: int i=ox123;(correct)
        int k=ox245a;(wrong)
         int k=123a;(wrong)

note:JVM takes the binary data ,octal data,decimal data,hexa decimal data convert in the form of decimal format and give the output as adecimal
example programme:
  class ndemo
{
public static void main(String args[])
{
  int i=24;
int j=o72;
int k=ox2a;
int l=ob10;
System.out.println(i);
System.out.println(j);
System.out.println(k);
System.out.println(l);
}
}
note:this programme run java 1.7 or above versions because binary values format does not suppport java 1.7 below versions.
output:
24
58
42
