java - Data type Double is displaying value 0.0 -

-

this question has answer here:

i have been programming javascript year , half now, , have began learning java syntax. when trying recreate simple program wrote in javascript, have ran trouble when using double data type. here code:

scanner input = new scanner (system.in); int questionstotal; int questionscorrect; double grade; system.out.println("how many questions there in total?"); questionstotal = input.nextint(); system.out.println("how many questions did correct?"); questionscorrect = input.nextint(); grade = questionscorrect / questionstotal * 100; system.out.println("your grade is: " + grade);

it isn't in snippet, java.util.scanner imported. when user enters values questionstotal , questionscorrect, process fine. however, grade variable not function planned. when printed, displays value of either 0.0, or 1.00, if input should decimal value. have tried using printf rather println, no avail. using wrong data type? can doubles not handle decimal value?

i appreciate feedback on possible semantic error, , apologize lack of experience in field. please let me know if there more information can given. answers appreciated.

try replace line in code:

grade = ((double)questionscorrect) / questionstotal * 100;

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
