Java try-catch-finally 代码执行顺序

测试用例

public class TestExceptions {

    public static void main(String[] args){
        try {
            String result = "";
            try {

                int i= 0;
                double val = 10/i;
                System.out.println("try ok!");
                result = "ok!";
            } catch (Exception e){
                result = "fail";
                e.printStackTrace();
                throw new Exception(e.getMessage());
            } finally {
                System.out.println("here in finally, result=="+ result);
            }
        } catch (Exception e){
            System.out.println("outter try catch, exception=="+ e.getMessage());

        }
    }
}

输出结果：
java.lang.ArithmeticException: / by zero
at TestExceptions.main(TestExceptions.java:12)
here in finally, result==fail
outter try catch, exception==/ by zero

结论：

try块代码抛出异常，则转到相应的catch块，被捕获异常；
在catch执行完，转入外部代码之前，先执行finally块。
无论是否抛出异常，finally块的代码都会被执行到。
