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() } } } * * * * * *  * * * * *  * * * *  * * *  * *...

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  Data sturcture  DataBases  Data Warehouse  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...
