3 . unsigned byte b = 0;
4 . b--;
5 .
6 .}
7 . }
What is the value of b at line 5?

• A.Compilation will succeed but the program will throw an exception at line 4.

Given:
AnInterface is an interface.
AnAdapter0 is a non-abstract, non-final class with a zero argument constructor.
AnAdapter1 is a non-abstract, non-final class without a zero argument constructor, but with a constructor that takes one int argument.
Which two construct an anonymous inner class? (Choose Two)
F.AnAdapter1 aa=new AnAdapter1(){}
G.AnAdapter0 aa=new AnAdapter0(){}
H.AnAdapter0 aa=new AnAdapter0(5){}
I.AnAdapter1 aa=new AnAdapter1(5){}
J.AnInterface a1=new AnInterface(5){}

Given:
1 . public class Foo implements Runnable (

3 . system.out.printIn("Running.");
4 . }
5 . public static void main (String[] args){
6 . new thread (new Foo()).start();
7 . )
8 . )
What is the result?

• A.An error at line 6 causes the compilation to fail.
• B.An error at line 1 causes compilation to fail.
• C.An exception is thrown.
• D."Running" is printed and the program exits.
• E.The program exists without printing anything.
