  5. The code does not compile.
  6. An uncaught exception is thrown.




Answer



B.

Note

Line 4 prints AAA and line 5 throws an Exception.

Line 6 catches the exception, line 7 prints BBB and line 8 calls System.exit, which terminates the JVM.

The finally block does not execute. 

public class Main {
  public void start() {
    try {/*from   w  ww .j  a v  a  2s . co m*/
      System.out.print("AAA");
      throw new Exception();
    } catch (Exception e) {
      System.out.print("BBB");
      System.exit(0);
    } finally {
      System.out.print("CCC");
    }
  }

  public static void main(String[] args) {
    new Main().start();
  }
}
