如何在Java中尝试更改变量? [英] How do I change a variable from a try in java?

问题描述

大家好，我试图在try语句中更改变量的值，以便在try之外影响变量，有人知道怎么做吗?

Hey everyone, im trying to change the value of a variable from within a try statement so that it will effect the variable outside of the try, does anyone know how to do this?

推荐答案

try块(与任何其他语句块一样)可以访问外部块变量.另一方面，如果在try块本身内部定义变量，则无法在外部进行更改(例如，参见^ ]).

The try block (like any other block of statements) may access outer blocks variables. On the other hand if you define a variable inside the try block itself then you cannot change it outside (see, for instance here[^]).
