import java.io.BufferedReader; import java.io.File; import java.io.FileReader; import java.io.IOException; public class ReadFile { public static void main(String[] args) throws IOException { String fileContent = readFileContent...

在代码里写入一个输入输出流即可。 具体实现如下: BufferedReader bf= new BufferedReader(new FileReader("file")); 注:其中file替换为文件路径; bf.readLine(); 注:即可实现一行一行读取txt文档。

import java.io.BufferedReader;import java.io.FileReader;public class Main {public static void main(String[] args) throws Exception {BufferedReader read = new BufferedReader(new FileReader("D:\\1.txt"));String line = "";while((l...

这个是文本流,先把文本读到内存中,再根据固定的格式去解析。按照换行解析 List list=new ArrayList(); String encoding = "GBK"; File file = new File("c:/test.txt"); if (file.isFile() && file.exists()) { InputStreamReader read = new ...

直接把 .txt后缀改为 .java (是不是你那没有文件后缀啊,选择窗口上面【工具】-【文件夹选项】-【查看】(勾寻隐藏已知文件类型的扩展名) 我不知道是不是你问的意思 一般记事本里面编完就是改后缀即可 在doc cmd 里面运行 用NetBeans 或Eclips...

调用时,类名.readFile("d:/1.txt");即可: public static String[] readFile(String sourceFileName) throws IOException { String[] array = null; Set result = new HashSet(); String lineText; BufferedReader reader = null; try { File s...

BufferedReader read1 = new BufferedReader(new InputStreamReader(new FileInputStream("txt1"));//要读取的文件txt1的路径 BufferedReader read2 = new BufferedReader(new InputStreamReader(new FileInputStream("txt2"));//要读取的文件tx...

java从txt中读出数据 按“|”解析字符串成数组,记得每个对应的值 插入数据库

import java.io.*;public class Demo{ public static void main(String[] args)throws Exception{ BufferedReader br = new BufferedReader(new FileReader("D:\\a.txt")); String lint = null; while((lint = br.readLine())){ if(lint.indexOf...

BufferedWriter bw = new BufferedWriter (new OutputStreamWriter (new FileOutputStream ("content.txt", true), "UTF-8")); 加true,表示追加
