Intorducation of data sturcture

Let’s start to introduction of data structure

Data is an integral part of an application or program .It defines a program ,so program is nothing ,Set of instructions to perform on data to get some output.Then without data there are no instructions enough . no use of instructions ,

The term of data we use many palace like 

  1. Data sturcture 

  2. DataBases 

  3. Data Warehouse 

  4. Big Data 

Let's start by introducing the data structure.

Data Structure

Data structure is the arrangement and collocation of data items.so that can be utilized and perform operations on data efficiently.Its all about arrangement and  efficient operation on data.

That question is where inside the main memory during execution of the program.


  So,without data structure there is no application. 

Every Application will have a set of instructions to perform on data.So that data is mondetry ,where it will capture the data inside main memory.

So, during the program execution how will the program manage the data inside the main memory and perform the operation that its data structure.

We took the example to understand the concept of the data structure.

  • CPU:

                 CPU will execute the program..this is the processor .This performs the operation on data.

  • Main memory:

                Main memory is temporary memory.This is working memory and also called primary memory.

  • HDD:

             This is permanent storage.

  If you look our PC that have 

  • CPU

  • RAM

  • Secondary Storage.

If look our mobile that have 

  • CPU

  • RAM(2GB,4GB,8GB)

  • Storage(32GB,64GB etc)

If we get install program or application on our PC or Mobile Phone thats keep it in the Program File

Where we will keep our data like 

  • Photo 

  • Video 

  • Music 

  • Projects etc.

That's are you keep it in Hard Disk or Mobile Storage.So, these are Data File

Every Application deals with some data. Like

  • MS-Words

  • Notepad

  • Chrome (If we search any webpage , the webpage come up internet and load in the main memory.)

So,every application or program installed on your mobile phone or PC dael with some data ,that data inside the main memory.for efficiently use that  data we organize such that inside memory.

Data Types in Java

  Data Types in Java  Data type:    Data type indicates the different sizes and various values that can be stored in the variable.  Types of data types in Java  1.Primitive data types  2.Non-primitive data types    Java Primitive Data Types  There are 8 types of primitive data types are as follows:  ★ boolean data type  ★ byte data type  ★ short data type  ★ char data type  ★ int data type  ★ long data type  ★ float data type  ★ double data type    Java Non-Primitive Data Types  Non primitive data types are:  ★Struct  ★Array  ★Class Program example to understand the datatypes in java   class Datatype {  public static void main(String[] args) {  int a=23;  float b=34.5f;  long c=90l;  byte d=78;  double e=78.8;  char f='A';  short x=56;  System.out.println("Primitive Data Types:");  System.out.println("The value of ...

Java Nested For Loop

  A for loop with another for loop is called nested for loop. Syntax: for(initialization;condition;increment/decrement){ for(initialization;condition;increment/decrement;){ }//inner for loop }//outer for loop  Example: public class nestedForloop{   public static void main(String[] args) {                         for ( int y= 1 ;y<= 3 ;y++){   for ( int x= 1 ;x<= 5 ;x++){    System.out.println(y+ " " +x);   }//inner loop  } //outer loop  System.out.print(“Nested For loop”); }  Pyramid *  * *  * * *  * * * *  * * * * * public class Pyramid { public static void main(String[] args) { for(int i=1;i<=5;i++){ for(int j=1;j<=i;j++){ System.out.print("* "); } System.out.println() } } } * * * * * *  * * * * *  * * * *  * * *  * *...
