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.");
        }
    }
}
