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。
