INTERVIEW QUESITIONS(WRITE ANSWERS IN COMMMENT BOX)

1.WHAT IS DIFFERENCE BETWEEN VARCHAR AND VARCHAR2?
2.WHAT IS FIRST OBJECT ORIENTED PROGRAMMING LANGUAGE?

PROPERTIES OF RDBMS IN ORACLE

1.data should store in the form of a table.a table can be different as collection of rows&columns
A horizontal lines as Rows or Records/touples
A vertical lines are known as fields or attributes/columns
the intersection of  rows&columns is known as cell
                              a cell is a place where we can store or a data.the other name of table can be known as entity/object.
 table/entity/object:
             fields/attributes/columns

 rows/records/touples





2.table should not contain duplicate column
3.while do inserts the records the table user no need to follow any specific order.
4.data base should not contain duplicate objects 
5.while do defines columns in the table user follow no need to order

WHAT IS WRAPPER CLASS & WAHT IS BOXING & UNBOXING&WHAT IS AUTO BOXING&AUTO UNBOXING

WHAT IS WRAPPER CLASSES:
                   In order to represent the primitive data type values with the concept of object we are going to
use some pre defined classes.
            The classes which we are using to represent primitive data values in the form of object are called as WRAPPER CLASSES.
                    to represent the each&every primitive datatype value in the form of object there will be a corresponding class is available.



        




all the wrapper classes are present inside a predefined package called as java.lang

Integer i1=new Integer(100);
Integer i2=new Integer("123");



WHAT IS BOXING:
                     the concept of representing the primitive data type value in the form of it's equivalent wrapper class object is known as boxing.
 int i=200;
Integer i1=new Integer(i);//boxing


WHAT IS UNBOXING:
                   the concept of getting back the primitive data value which is present inside wrapper class object to corresponding primitive data type value is known as unboxing>
              int i=100;
              integer i1=new integer(i)//boxing
              int j=i1.value()//unboxing
 in order to perform unboxing we are going to use the predefined methods which are present inside wrapper classes
ex:
        class wdemo()
         {
           public static void main()
           Integer i1=new Integer(100);
           system.out.println(i);
           Integer i2=new Integer("1234");
          system.out.println(i2);
           int i=i1.intvalue();
           int j=i2.intvalue();
           int k=i+j;
           system.out.println(k);
           Integer i3=new Integer();
              system.out.println("hello");
}
}

output:
              100   
              1234   
              1334
               hello

AUTO BOXING:
                    The concept of representing the primitive data value in the form of corresponding wrapper class object automatically by the jvm is known as auto boxing.
                    int i=100;
                    Integer i1=i;//integer i1=i Integer(i);

ex:
         int i=300;
         Integer i1=new Integer(400);
         int j=i+i1;


AUTO UNBOXING:
                          
                  The concept of geeting back the primitive data type value which is present inside wrapper class object automatically by the jvm is known as auto boxing.
                     Integer i2=new integer(200);
                      int j=i2//int j=i2.intvalue();

ex:
         int i=400;
         Integer i1=new Integer(300);
         Integer i2=i1+i;
ex:
        class wdemo2()
         {
             public static void main()
             {
              Integer i1=new Integer(100);
              Integer i2=new Integer("1234");
              Integer j=i1+i2;
              System.out.println(j);
               System.out.println("hello");
       }
     } 
output:
          1334
           hello

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.

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.

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.
