在try块中初始化变量，解决方法? [英] initialising a variable inside try block, a workaround?

问题描述

我有一个try-catch块；在try中，我从控制台读取变量N并初始化Array[N].我以后需要使用Array.如果在try块之外使用它，则会出现错误

I have a try-catch block; inside try, I read variable N from console and initialize an Array[N]. I need to use Array later. If I use it outside try block, I get an error

java variable may not have been initialized.

我理解它，但是我应该怎么做，将整个程序写在try块中，真的吗?这种程序的可读性较差，我在不可能使用exceptions的代码上使用try.有解决方法吗?我尝试了一个boolean变量，该变量检查是否存在异常，并稍后在if语句中使用它-没有结果.

I understand it, but what should I do, write the whole program inside try block, really? Readability of such program is worse and I use try on the code where is no exceptions are possible. Is there a workaround? I tried a boolean variable which checks was there an exception and use it later in a if statement - no results.

推荐答案

Object[] yourArray = null;
try {
  ...
}
