Java 使用外部文本文件中的数据 [英] Java Use Data from External Text File

问题描述

我有一个包含前 1000 个素数的文本文件，我编写了一个方法来从所述文本文件中读取数据.

I have a text file containing the first 1000 prime numbers and I have written a method to read the data from said text file.

我想知道如何使用此文件中的数据并将其应用于另一种方法.

I would like to know how to use the data from this file and apply it to another method.

大致如下:

read data from file;
use first eight numbers and apply to this method;

任何帮助将不胜感激.

推荐答案

从文件中读取很简单，假设每个数字有一行 -

Reading from file is simple, assuming you have one line per number -

BufferedReader br = new BufferedReader(new FileReader("<your-text-file>"));
String txtNum;
while((txtNum = br.readLine()) != null)
{
   //txtNum is the number read, use it however you need
   if (txtNum.length() > 8) {
      thisMethod(txtNum.substring(0, 8));
   }
}
