boolean test() throws Exception { boolean ret = true; try { int b = 12; int c; for (int i = 1; i >= -2; i--) { c = b / i; System.out.println("i=" + i); } return true; } catch (Exception e) { System.out.println("testEx2, catch exception"); ret = false; throw e; } finally { System.out.println("testEx2, finally; return value=" + ret); return ret; }}

这是一种很不好的写法。

开始认为会输出 

    i=12

testEx2, catch exception

testEx2, finally; return value=false 但事实是

   i =12

testEx2, finally; return value=false 原因是finally里写return  return会冲掉上边的return 并且干掉catch抛出的异常
