why doesn't my calculator work? - JAVA

[hirushaadi]

 

 

 

 

what ever i type, the answer i get is 32.0

 

and why cant i keep this a double with the getText

 

I USE NETBEANS

 

ANY HELP WOULD BE APPRECIATED - Thank You!

getText() returns a string, you have to convert it to a double before you can do any math on it.

[mariushm]

also get in the habit of using ( ) where convenient. 

 

For example  :

 

result = 9/5*hirusha+32   

 

Will give the right value in the result variable, because  division and multiplication have the same priority if my Java knowledge is accurate, so they'll be processed left to right , 9 / 5 and then the result multiplied by hirusha variable ... but for clarity it would be best to write  (9/5) * hirusha + 5  - this way any reader instantly knows the result of the fraction is multiplied, and you definitely didn't mean   9 / ( 5 * hirusha)
