## Try...Catch... progress declear
when using try/catch, if you has not return, it mean you allow exception occur and let programe go on

```java
public class TestTryCatch {
    public static void main(String[] args) {
        int a = 0;
        try{
            int ret = 1/a;
        }catch(Exception e){
            System.out.println("div 0 error");;
        }

        System.out.println("process done");
    }
}
/* console output: 
* div 0 error
* process done
* Process finished with exit code 0
*/
```
you can see, even exception occur, it goes on.
