ok...
see i did try to compile the program....
Question 1
public class Basics {} // 1
class Basics1 {} // 2
protected class Basics2 {} // 3
private class Basics3 {} // 4
Class Basics4 {} // 5
i only got compile time error at line 5 cause the class keyword should have all the characters in small letters....
but the answers say 3 and 4 line will also have compile time error....
