将CSV文件导入Java [英] Importing a CSV File into Java

问题描述

在我写的程序中，我想要导入CSV文件。此时，它需要一个基本的文本文件。

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.

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

我知道对于CSV导入使用File可能不是最节省时间的东西使用。什么是导入CSV文件的最有效的方法？

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?
