| 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-tuitorial.org/ http][http://spoken-tuitorial.org/ ://][http://spoken-tuitorial.org/ spoken][http://spoken-tuitorial.org/ -][http://spoken-tuitorial.org/ tutorial][http://spoken-tuitorial.org/ .][http://spoken-tuitorial.org/ org][http://spoken-tuitorial.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.
