Loop or Control Structure Statement in Java:-


It is used to enumerate large statements of data using a single repeatable block. Loop is also called control Structure.

It is used to solve range based problem, for example, we want to display marks of 5000 students.

Loop is mostly used in Array and Collection type variable.

Loop uses three statements for program execution


                                  Forward                                 Backward

initialization  :-         i= min                                     i=max


Condition :-              i<=max                                    i>=min


Iteration                    i++                                           i--




Type of Loop:-


1) Entry Control:-

     First Check Condition Then Execute Statement

     1.1) while:-   

This loop will work when the condition will be true, while loop can be used to create a finite and infinite based program both.

but we mostly prefer infinite based program using while because for loop provide simple structure to implement the finite based program.

finite while loop:-


Syntax of While Loop:-


 initialization;

while(condition)   
{
      Statement;
      increment;

}


example

int i=1;

while(i<=10)
{
    System.out.println(i);
   i++;

}



infinite

int i=1;

while(true)
{
    if(i>10)
    break;
    System.out.println(i);
   i++;

}


Program of While Loop to calculate a table to understand while loop properly:-

import java.util.Scanner;
class Table
{
   public static void main(String args[])
   {
       int num,i;
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter number for table");
       num=sc.nextInt();
       i=1;
       while(i<=10)
       {
          System.out.println(num+ "*" + i + "=" + (num*i));
          i++;

       }
      System.out.println("Total number of step "+i);


   }


}

WAP to create a table of any number using infinite Loop:-

import java.util.Scanner;
class Table
{
   public static void main(String args[])
   {
       int num,i;
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter number for table");
       num=sc.nextInt();
       i=1;
       while(true)
       {
          System.out.println(num+ "*" + i + "=" + (num*i));
          if(i>10)
           break;
          i++;

       }
     // System.out.println("Total number of step "+i);


   }


}


limitation of while loop:-

1)  Complex structure hence it can not be managed in nested sequence easily.

2)  take more process time as compare to for loop




           
   

 1.2 for -

using this we can contain all statements using for statements, it provides a simple syntax structure as compared to a while and do-while loop.

for loop is mostly used to create a finite condition-based program.


      1        2              4
for(init; condition; iteration)
 {
        3
        statement; 
 }



finite for loop example:-


import java.util.Scanner;
class Table
{
   public static void main(String args[])
   {
       int num,i;
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter number for table");
       num=sc.nextInt();
       
       for(i=1;i<=10;i++)
       {
          System.out.println(num+ "*" + i + "=" + (num*i));
        
         

       }
     // System.out.println("Total number of step "+i);


   }


}


Infinite for loop example:-

import java.util.Scanner;
class Table
{
   public static void main(String args[])
   {
       int num,i;
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter number for table");
       num=sc.nextInt();
       i=1;
       for(;;)
       {
          System.out.println(num+ "*" + i + "=" + (num*i));
          if(i>10)
           break;
          i++;

       }
     // System.out.println("Total number of step "+i);


   }


}


Write a program to calculate factorial of any entered number?

import java.util.Scanner;
class Fact
{
   public static void main(String args[])
   {
       int num,i,f=1;
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter number for table");
       num=sc.nextInt();
       
       for(i=1;i<=num;i++)
       {
         f=f*i;  #f = 120
        
       }
      System.out.println("result is "+f);


   }


}


Nested For Loop:-   We will write more than one for loop using a nested sequence, it Contains a collection of outer for loop and multiple inner for loop.


for(init;condition;iteration)
{
   for(init;condition;iteration)
   {
            Statement;
