1、InputStreamReader

import java.io.BufferedReader;import java.io.FileInputStream;import java.io.InputStreamReader;public class Test {public static void main(String[] args) {// TODO Auto-generated method stubFileInputStream fis = null;BufferedReader reader = null;try {//设置读取位置fis = new FileInputStream("d:\\text2.txt");//转换流InputStreamReaderreader = new BufferedReader(new InputStreamReader(fis));//缓存区String str = "";//读取数据while((str = reader.readLine()) != null) {System.out.println(str);}} catch (Exception e) {// TODO: handle exceptione.printStackTrace();}finally {try {//关闭流reader.close();fis.close();} catch (Exception e) {// TODO: handle exception}}}}

2、OutputStreamWriter

import java.io.BufferedWriter;import java.io.FileOutputStream;import java.io.OutputStreamWriter;public class Test {public static void main(String[] args) {// TODO Auto-generated method stubFileOutputStream fos = null;BufferedWriter writer = null;try {String content = "要写出的内容";fos = new FileOutputStream("d:\\text2.txt");//转换流OutputStreamWriterwriter = new BufferedWriter(new OutputStreamWriter(fos));writer.write(content);} catch (Exception e) {// TODO: handle exceptione.printStackTrace();}finally {try {//关闭流//注意关闭顺序，最后关闭FileOutputStream流，否则报错writer.close();fos.close();} catch (Exception e) {// TODO: handle exceptione.printStackTrace();}}}}
