将 CSV 文件导入 Java

Importing a CSV File into Java

提问by Nick Welki

In the program I am writing, I want to be able to import CSV files. At the moment, it takes a basic text file in.

在我正在编写的程序中，我希望能够导入 CSV 文件。目前，它需要一个基本的文本文件。

File mainemails = new File ("mainemails.txt");

I know that for CSV imports using File is probably not the most time-efficient thing to use. What would be the most efficient way to import a CSV file? Would I have to download any new libraries to use an efficient method?

我知道使用 File 导入 CSV 可能不是最省时的方法。导入 CSV 文件的最有效方法是什么？我是否必须下载任何新库才能使用有效的方法？
