java 读取 txt 文件
学习小记:
1、首先要根据路径获取你的 txt 文本文件。File file = new File(path);
2、将获取到的这个字节码流读进缓存。new FileInputStream(file) ;
3、然后对刚才读进缓存的输入流进行解读,生成对应字节流。InputStreamReader(readIn)
4、再然后通过 BufferedReader 这个类进行一行一行的输出。bufferedReader.readLine()
import java.io.BufferedReader; import java.io.File; import java.io.FileInputStream; import java.io.InputStreamReader;
public static void ReadTxt () { try { File file = new File("E:\\text.txt"); FileInputStream readIn = new FileInputStream(file); InputStreamReader read = new InputStreamReader(readIn, "utf-8"); BufferedReader bufferedReader = new BufferedReader(read); String oneLine= null; while((oneLine= bufferedReader.readLine()) != null){ System.out.println(lineTxt); } read.close(); } catch (Exception e) { System.out.println("读取文件内容出错"); e.printStackTrace(); } }
