# Java `BufferedReader`示例 > 原文： [https://howtodoinjava.com/java/io/how-to-read-file-in-java-bufferedreader-example/](https://howtodoinjava.com/java/io/how-to-read-file-in-java-bufferedreader-example/) 如果要使用[`BufferedReader`](https://docs.oracle.com/javase/10/docs/api/java/io/BufferedReader.html)在 Java 中讀取文件，請使用以下代碼作為模板，并按自己的方式重復使用它。 `BufferedReader`從字符輸入流中讀取文本，緩沖字符，以便有效讀取字符，數組和行。 ## 1）使用不帶`try-with-resources`的`BufferedReader`（在 Java 7 之前） ```java package com.howtodoinjava.examples.io; import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; public class BufferedReaderExample { public static void main(String[] args) { BufferedReader bufferedReader = null; try { String currLine; bufferedReader = new BufferedReader(new FileReader("C:\\temp\\testOut.txt")); while ((currLine = bufferedReader.readLine()) != null) { System.out.println(currLine); } } catch (IOException e) { e.printStackTrace(); } finally { try { if (bufferedReader != null) bufferedReader.close(); } catch (IOException ex) { ex.printStackTrace(); } } } } ``` ## 2）將`BufferedReader`與`try-with-resources`一起使用（Java 7 及更高版本） ```java package com.howtodoinjava.examples.io; import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; public class BufferedReaderExample { public static void main(String[] args) { try (BufferedReader bufferedReader = new BufferedReader(new FileReader("C:\\temp\\testOut.txt"))) { String currLine; while ((currLine = bufferedReader.readLine()) != null) { System.out.println(currLine); } } catch (IOException e) { e.printStackTrace(); } } } ``` **祝您學習愉快！**
