You don't have a constructor that takes a String parameter.

iswan, please don't start a new thread for the same or a closely related problem. I've merged your two threads here.

With regard to your second question:
1) A constructor does not have a return type. public void BiodataPelajar(String str) is a method, not a constructor.
2) Java is case sensitive, and all Java keywords are lower case.
