导入Textfile并在Java中逐行读取 [英] Import Textfile and read line by line in Java

问题描述

我想知道如何导入文本文件。我想导入一个文件，然后逐行阅读。

I was wondering how one would go about importing a text file. I want to import a file and then read it line by line.

谢谢！

推荐答案

我不知道导入文件是什么意思，但这是使用标准Java类逐行打开和读取文本文件的最简单方法。 （这应适用于所有版本的Java SE返回JDK1.1。使用Scanner是JDK1.5及更高版本的另一个选项。）

I've no idea what you mean by "importing" a file, but here's the simplest way to open and read a text file line by line, using just standard Java classes. (This should work for all versions of Java SE back to JDK1.1. Using Scanner is another option for JDK1.5 and later.)

BufferedReader br = new BufferedReader(
        new InputStreamReader(new FileInputStream(fileName)));
try {
    String line;
    while ((line = br.readLine()) != null) {
        // process line
    }
} finally {
    br.close();
}
