Even the 4th Question answer is wrong : Looks like answer chocies and answers are messed up.

import java.util.*; 
public class MyScan { 
public static void main(String[] args) { 
String in = "1 a 10 . 100 1000"; 
Scanner s = new Scanner(in); 
int accum = 0; 
for(int x = 0; x < 4; x++) { 
accum += s.nextInt(); 
} 
System.out.println(accum); 
} 
} 

What is the result?

A.1
B.11
C.111
D.1111
E.Compilation fails.
F.Class2 has-a Class1.
G.An exception is thrown at run time.
