00:01	'જાવા માં એરિથમેટિક ઓપરેશન પરના આ ટ્યુટોરીયલમાં સ્વાગત છે.
00:05	આ ટ્યુટોરીયલ માં, તમે વિવિધ એરિથમેટિક ઓપરેશન વિશે શીખશો જેવા કે Addition Subtraction Multiplication Division અને તેમને કેવી રીતે ઉપયોગમાં લેવું.
00:16	આ ટ્યુટોરીયલ માટે આપણે Ubuntu 11.10, JDK 1.6 અને Eclipse 3.7 ઉપયોગ કરી રહ્યા છીએ.
00:24	આ ટ્યુટોરીયલ અનુસરવા માટે તમારી સિસ્ટમ પર એક્લીપ્સ સ્થાપિત હોવું જોઈએ.
00:28	અને તમને Eclipse માં કેવી રીતે ફાઈલ બનાવવી, સંગ્રહવી અને રન કરવી તે ખબર હોવી જોઈએ.
00:32	જો નહી તો સંબધિત ટ્યુટોરીયલ માટે દર્શાવેલ અમારી વેબસાઈટ જુઓ.
00:42	અહીં ઓપરેટરો અને તેઓ કરતા ગાણિતિક ઓપરેશનોની યાદી છે plus સિમ્બોલ સરવાળા માટે minus બાદબાકી માટે asterisk ગુણાકાર માટે અને slash ભાગાકાર માટે
00:54	આપણે તે દરેકને વિગતવાર જોઈશું.
01:05	અહીં આપણી પાસે ઇક્લિપ્સ IDE અને બાકીના માટે કોડ જરૂરી માળખું છે.
01:10	આપણે Arithmetic Operations નામનો ક્લાસ બનાવ્યો છે અને main મેથડ ઉમેર્યી છે.
01:17	ચાલો અમુક વેરિયેબલ ઉમેરીએ.
01:22	int x = 5;
01:26	'int y = 10; int result
01:35	x and y will be the operands and the result will store the output of operations.
01:41	Let us add them and print the result. Result= x+y; system. out. println 'in parantesis result
02:10	Save it with Control S and control F11 to Run
02:17	We see, that the output of addition is stored and the value has been printed
02:24	Now Let us change the values . x=75,y = 15
02:37	Save it Run
02:42	we see that the output has changed accordingly
02:48	Now let us try negative values. 'y = -25.
02:57	Save Run.
03:02	we see that the output of 75 plus -25 has been printed
03:10	Now let us try subtraction. 'y = 5 and change x+y to x-y
03:25	Save it Run.
03:32	we see that the output of 75-5 has been printed,
03:38	Now Let us try multiplication. Change minus to asterisk
03:46	Save and Run.
03:52	we see that by using asterisk we could multiply 75 by 5. .
03:58	Now let us try division Remove asterisk and type slash
04:07	Save it Run.
04:13	As we can see, the output is as expected.
04:18	Now let us see what happens when the expected result is a decimal point number.
04:24	Change 5 to 10
04:28	The result must be 7.5.
04:30	So let us change the result to a float.
04:43	Save it Run.
04:50	Note that although the expected result is 7.5, we get output as 7.0
04:57	This is because both the operands involved in the division are integers.
05:01	Let us change y to a float. y=10f
05:15	Save Run.
05:21	Now we can see that the result is as expected.
05:24	Keep in mind that when the expected result is a float, one of the operands must be a float to get the expected output.
05:32	Now let us see what happens when there is more than one operator.Remove all the operands
05:48	int result= 8+4-2. Save it ,run
06:09	As we can see, the output is as expected.
06:12	Now Change minus to a slash
06:19	Now the output would be 6 if the addition is done before division.
06:25	Or it would be 10 if division is done before addition.
06:30	Let us Run and see the output.
06:38	As we can see, the output is 10 and the division is done before addition. This is because the division operator has more precedence than the addition operator.
06:50	In such situations, if we need to override the precedence, we use parentheses.
07:04	By adding parentheses, we instruct Java to do the addition before the division.
07:10	Let us run the file now.
07:15	As we can see, addition has been performed first and the output is 6 as expected.
07:22	As a rule, keep in mind to use parentheses when the order of operations is not clear.
07:36	This brings us to the end of this tutorial.
07:40	we have learnt
07:41	How to perform basic mathematical operations in Java.
07:44	operator precedence, and,
07:45	How to override it.
07:49	As an assignment for this tutorial Find out what is meant by the modulo operator and what it does.
