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：

1 // 14.2 Will the code in finally {} be executed if there is a return statement inside try {} or catch{}? 2 // The answer is yes. 3 // OUTPUT: 4 // Hello world. 5 // An exception is caught: java.lang.ArrayIndexOutOfBoundsException: 2 6 // Finally you're here. 7 public class TestJava { 8     public static void main(String[] args) { 9         try {10             System.out.println("Hello world.");11             int[] a = new int[2];12             a[2] = 1;13             return;14         } catch (Exception e) {15             // TODO: handle exception16             System.out.println("An exception is caught: " + e);17             return;18         } finally {19             System.out.println("Finally you're here.");20         }21     }22 }
