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.");
         }
     }
 }
