字符流缓冲区

字符流缓冲区和字节流缓冲区底层运行差异不大

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class IoDemo {
    public static void main(String[] args) throws IOException {
        methord1();
        methord2();
    }

    private static void methord2() throws IOException {
        // TODO Auto-generated method stub
        BufferedWriter b = new BufferedWriter(new FileWriter("e:/lishuai.txt"));
        b.write("lishuai");
        //newLine方法是换行的作用。
                b.newLine();
        b.write("shuai");
        b.newLine();
        b.flush();
        b.close();
    }

    private static void methord1() throws IOException {
        // TODO Auto-generated method stub
        BufferedReader b = new BufferedReader(new FileReader("e:/lishuai.txt"));
        String ch = null;
        while ((ch = b.readLine()) != null) {
            System.out.println(ch);
        }
        b.close();

    }
