Question

Given: 

public class Main {
  class MyClass implements AutoCloseable {
    public void close() throws Exception {
       System.out.print("l");
    } //  w w  w  .j a v  a  2s .  co  m
  }
  class MyClass2 implements AutoCloseable {
    public void close() throws Exception {
       System.out.print("g");
    } 
  }
  public static void main(String[] args) throws Exception {
    new Main().run();
  }
  public void run() throws Exception {
    try (MyClass l = new MyClass();
         System.out.print("t");
         MyClass2 g = new MyClass2();) {
      System.out.print("2");
    } finally {
      System.out.print("f");
    } 
  } 
}

What is the result? 

A.   2glf
B.   2lgf
C.   tglf
D.   t2lgf
E.   t2lgf
F.   None of the above; main() throws an exception
G.   Compilation fails



G is correct.

Note

System.out.println cannot be in the declaration clause of a try-with-resources block because it does not declare a variable.

If the println was removed, the answer would be A because resources are closed in the opposite order they are created.
