	`1`	`+##finally语句是否一定会执行`
	`2`	`+###问题`
	`3`	`+在try/catch块中我加了return语句。那么finally语句是否会调用呢?`
	`4`	`+代码例子`
	`5`	+```java
	`6`	`+try {`
	`7`	`+ something();`
	`8`	`+ return success;`
	`9`	`+}`
	`10`	`+catch (Exception e) {`
	`11`	`+ return failure;`
	`12`	`+}`
	`13`	`+finally {`
	`14`	`+ System.out.println("i don't know if this will get printed out.");`
	`15`	`+}`
	`16`	+```
	`17`	`+我知道我可以直接运行看看,但因为我google了一番后,并未发现相关答案,所以我提出了这个问题,大家可以展开讨论`
	`18`	`+`
	`19`	`+###回答`
	`20`	`+finally语句会被调用,除了以下情况:`
	`21`	+1. 你调用了`System.exit()`
	`22`	+2. 另外一个线程通过[`interrupt`](https://docs.oracle.com/javase/8/docs/api/java/lang/Thread.html#interrupt--)中断了当前线程
	`23`	`+3. JVM发生crash`
	`24`	`+`
	`25`	`+`
	`26`	`+//译注:第二点有待验证,评论区有人质疑`
