题目：在java的try-catch-finally语句块里，如果catch里面有return语句的话，finally还会被执行吗？

解法：会。

代码：

 // 14.2 Will the code in finally {} be executed if there is a return statement inside try {} or catch{}?

 // The answer is yes.

 // OUTPUT:

 // Hello world.

 // An exception is caught: java.lang.ArrayIndexOutOfBoundsException: 2

 // Finally you're here.

 public class TestJava {

     public static void main(String[] args) {

         try {

             System.out.println("Hello world.");

             int[] a = new int[2];

             a[2] = 1;

             return;

         } catch (Exception e) {

             // TODO: handle exception

             System.out.println("An exception is caught: " + e);

             return;

         } finally {

             System.out.println("Finally you're here.");

         }

     }

 }
