Hi sandy

 property ="studentid"

is the way to call the set methods (setstudentid), well each property start with not uppercase, but your java code start withuppercase

i saw this common error, the obvious answer is change your property with uppercase, but some times dont work, strange for me!

so,the answer is to change your set methods in your java file to no uppercase

 setStudentid by setstudentid
 setRollnumber by setrollnumber
 setStream by setstream

if i dont remember try to not use the same names to the variables and methods

i hope that my help can resolve your problem
