I have got some good questions for you guys. 
1) name the keyword used to stop inheritance. 
2) name the keyword for implementing interfaces. 
3) give an example of run time polymorphism. 
4) name the main class containing exceptions. 
5) give output:
int i=0;
if(false & ++i<100);
System.out.println(i);
If(false&&++i<100);
System.out.println(i);
