each catch clause is examined in turn, from first to last, to see whether the type of the exception object is assignable to the type declared in the catch
In Java, will the code in the finally block be called and run after a return statement is executed? The answer to this question is a simple yes – the code in a finally block will take precedence over the return statement. Take a look at the code below to confirm this fact: ...

1. Overview In this tutorial, we’ll explain the return keyword in Scala. The Scala programming language, much like Java, has the return keyword, but its use is highly discouraged as it can easily change the meaning of a program and make code hard to reason about. 2. Introduction In ...
Exit codes in Java are represented by integers, with 0 typically indicating a successful execution and non-zero values indicating various error conditions. The specific meaning of each exit code can vary depending on the system and the application. ...
The return keyword is not “optional” or “inferred”; it changes the meaning of your program, and you should never use it. 由于Scala是一种基于JVM的语言,因此大多数程序员都是从Java转过来的,因此可能会习惯于使用return来写代码。 但是Scala作为一种支持函数式编程的语言,是不推荐大家使用return表达式...
The only time this would not apply is if some of the "errors" signalled are really warnings - meaning that they should not actually interrupt the flow of execution, but they indicate possible problems that should be logged for investigation. In this case, it's probably appropriate to make ...

A lot of people are confused about that, they think they can set a return value in the finally block and it will return that value to the caller but it won't , the program will return (which is what I was meaning by method "finishing" because to the caller, the method is finished...
The spacing around the asterisk is a matter of style and doesn’t affect the functionality; it can be written as int *ptr; with the same meaning. Note that the next sample code uses the std::array container and calls the data() method to retrieve the pointer where the array elements ar...
