Time'	Narration
00:02	Welcome to the spoken tutorial on for loop in java.
00:07	In this tutorial, you will learn how to use the for loop in Java.
00:12	For this tutorial we are using Ubuntu 11.10, JDK 1.6 and Eclipse 3.7.0
00:24	For this tutorial, you should have knowledge on relational operators and if statement in Java.
00:32	If not, for relevant tutorial please visit our website which is as shown http://spoken-tutorial.org.
00:40	Here is the syntax of the for loop.
00:44	It consisits of initialization, loop condition and increment.
00:51	Then it has the for block which keeps on executing till the loop condition is true.
01:00	Now, let us try out an example in Eclipse.
01:04	So switch to eclipse
01:07	We already have a class named ForLoopDemo.
01:12	Let us add the for loop inside the main method.
01:17	So Inside the main function, type int i semicolon.
01:24	Then for within parenthesis i equal to 0 semicolon i less than 10 semicolon i equal to i plus 1.
01:45	This statement decides how the loop is going to progress.
01:53	i =0 is the starting condition for the loop.
01:58	This condition allows the variable to be initialized.
02:05	i<10 is the loop running condition.
02:09	If the condition is true then the for block will be executed.
02:14	Else it will be ignored.
02:17	That means when i becomes more than or equal to 10, the block is not executed.
02:25	Then i= i+1 , states how the loop variable is going to change.
02:32	Here, the value of i starts with 0.
02:35	It keeps increasing by 1 for every iteration of the loop until it becomes 10.
02:42	Now let us do something with i.
02:46	So open and close curly brackets.
02:49	Inside the curly brackets type System dot out dot println and print i into i.
03:06	This will print the square of each number from 0 to 9.
03:11	Let us see the output.
03:13	So save and run the program
03:17	As we can see, the loop run over numbers from 0 to 9.
03:23	The square of the number has been printed in each iteration.
03:28	Now let us print all the 2 digit numbers that are multiples of 3 or 5.
03:37	So, i should have values from 10 to 99.
03:42	So change i equal to 0 to i equal to 10.
03:48	And i less than 10 to i less than 100.
03:54	Then inside the curly brackets We print the number only if it is a multiple of 3 or 5.
04:03	So type,
04:04	if within brackets i mod 3 double equal to 0 or within brackets i mod 5 double equal to 0.
04:32	This statement checks whether i is divisible by 3 or by 5.
04:38	Then, in curly bracket we print the value of i
04:50	Now, let us see the output.
04:52	So save and run the program
04:56	We can see that the numbers are either multiples of 3 or 5. In this way we use for loop in Java
05:11	We have come to the end of this tutorial.
05:14	In this tutorial we have learnt how to use for loop in java.
05:20	For assignment , a three digit number is called Armstrong Number if it is equal to the sum of cubes of its digits.
05:29	For example, 153 is equal to 1 cube plus 5 cube plus 3 cube.
05:36	Find all such 3 digit numbers.
