[@dell4559]

anyone, please help me at 13:00 Exception in Application start method java.lang.reflect.InvocationTargetException and Error in setting onAction as #handleButtonAction

[@ferfykins]

Does this calculator work with multiple operations in one operation?

[@Mercio2]

Great tutorial!

[@ikramalouane4647]

it's the same thing with intilij ?? because the metode handTheButton doesn't been creating in my intilij i need your help please

[@xx-qd5ol]

I tried declarin "operation" and "data" inside the method, but it doesn´t work. It only works if you declare them as attributes, but why is that so?

[@aparnagodekar8727]

Sir, I want to know if you maximize the screen by dragging at that time how to set positions of all the elements .That is how to make it Responsive

[@GenuineCoder]

Hi, In order to make your layout responsive, you will have to design it in that way. I hope this video kzbin.info?o=U&video_id=fl6Wp1I9wHQ helps

[@famzi733]

Thank you.

[@mohammidsaeedi6023]

Please can you make it as speach calculator

[@abbadkamel8839]

so i have little question i wish u help me little : why we have write : display.setText(display.getText() + "3"); and for this display.setText(String.valueOf(ans)); ----> u did it to make it String again i m right coz ans is float !!?

[@GenuineCoder]

Hi, I already explained display.setText(display.getText() + "3") in your previous comment. Now let us consider display.setText(String.valueOf(ans)) -> You can call setText() only with string. ans is a float type and you have to convert float to string for displaying it. -> During calculation, you cant add/subtract/divide/multiple strings. Only numbers can be processed. So, you have to convert string to float. For converting String to float, you can use Float.parseFloat(); Eg :- You cant add "10" and "12". What you can do is int a = Integer.parseInt("10"); int b = Integer.parseInt("10"); int ans = a+b; String result = String.valueOf(ans). Hope you understood.

[@abbadkamel8839]

Oooooh okey okey i got it jknow we should convert to work coz here is calculator yeah yeah u have right thanx uu soo much for reply i wish u keep doining this coz u are great programmer

[@bens1752]

So my code is the same and it works in all the same ways except the clear button isn't working. Is there a different way to do this in the newer versions of Java?

[@bens1752]

Never mind I figured it out.

[@bens1752]

Just finished the version, fantastic.

[@abbadkamel8839]

how u did that !?

[@Yes-ok5me]

@@abbadkamel8839 update java maybe or write like the video

[@manalbenchrif2961]

when i use try catch i had an error in ans =initialize ans!! whyyy?? and THANK YOU

[@henrykashyap8913]

i tried display.setText but it display is coming in italic, tried importing but nothing happens?

[@Yes-ok5me]

in scence builder check this textfield or label in properties-font-style-change it to normal

[@deepakmandal2809]

try {result = (data1 / data2); if (data2 == 0) { throw (new ArithmeticException()); } display.setText(String.valueOf(result)); break; } catch(ArithmeticException e) { display.setText("Math Error"); }

[@RiskyCapital]

Ty

[@giuseppemaragno8700]

Someone can pls explain me the "Float data = Of"? What is it referring to?

[@mmusa6486]

Float data type is used to store foating point numbers i.e numbers with decimal points whenever any number is declared using float you should endeavour to add "f" at the vback of such number. e.g.. flaot myNum = 67.56f

[@abbadkamel8839]

well i should comment i very like ur tuto u show every thing that soo cool , but there is just one thing bad in ur tuto that u dont explain more like why we do : display.setText(display.getText() + "3"); coz u know im beggine here i dont know many things about those thing i wish u explain more for us and thanx u thanx u soo mcuh

[@GenuineCoder]

Hi, When you consider the audience, there are a wide variety of them. There are beginners, intermidate and experts. So, I cant go for explaining too little or too much. That's why I keep it in the middle. Coming back to the question : What display.setText(display.getText() + "3") means. It is simple. Suppose you are going to type 253 using the given buttons. Then at first you press : 2 -> Display : 2 Then you press : 5 (If I have used display.setText("5"), then I will loose 2 and only 5 will remain. So, what I have done is, I took in the already present 2 and append 5 to it). -> Display : 25 Then you press : 3 -> Taking already present 25 and adding 3. Hope you got the point.

[@abbadkamel8839]

Ooooh okey okey i see now that why w have write (display.getText() + "3") on display.setText(....) yeah it make sense ... thanx u to explain that thanx u so much

[@BoLeee]

Thanks!

[@Amangupta-cd8to]
