yeah its so helping and enjoyable. thank for video. but i think there should a tag on display cause we try to calculate a huge amount the numbers are out of display. is this possible to restrict display up to limited numbers??

[mdumser]

yes

verryy good i am beginner for swings ,it ws verry helpfull

to save memory u culd have used boolean :) rather that =0 and >0 ,boolean is meant fr the same :)

@251progression hey dude, thx fr highlighting

same was in my mind earlier :)

by the way,there is no need to take another variable,

jst make decimalClick=1 on equal to press.

[251progression]

I have a small improvement: As the code is now, you can click the decimal-button after the equals(answer)-button and get a second decimal in the display - yielding an error. To remove this way of adding a second decimal, add a new variable called "int equalsClick;" in the top of the code. In the code for the clear button add: "equalsClick=0;" and in the equals-button code add: "equalsClick=1;". Finally in the decimal-button code replace the "if" code with "if(decimalClick==0 && equalsClick==0)"

+/- button works

use this code on button: plusminus = (Double.parseDouble(String.val­ueOf(display.getText()))); plusminus = plusminus*(-1);

 display.setText(String.valueOf­(plusminus));
