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

HISTORY OF C LANGUAGE

In c family there are different languages like following the chart:
 

the language B was developed by ken thmson in the year 1968 at AT&T( American Telephone and Telegraph Company)Bell labs.
By adding the new features do a B language a new language was developed that is 'C'
  the C language was developed by denis ritche and ken thmson this language was developed in a time period from 1970-1973,but the major invention development was happend in the year 1972.
the c language was developed at AT&T bell labs.

what is system.out.println() in java language???

system.out.println():
                system is predefined class which is available in java.lang predefined package.
                                       out is a static reference varaiable of system class,which represnts the object of print stream class
println():
           println is a non static method which is present inside print stream class
printstream():
            printstream is a pre defined class which is available in java.io predefined package
  class system
  {
    static print stream out=new printstream();
     }

class printstream()                                            

{

   void println()
    {
       ------------
        --------------
     }
  void print()
{
  ------------
      -------------
}
void printf()
{
 --------------
----------------
}
}
