使用BufferedReader读取文本内容

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class readtxt {
    public static void main(String[] args) throws IOException {
//        FileReader fr = new FileReader("read.txt");
//        BufferedReader br = new BufferedReader(fr);
      BufferedReader br = new BufferedReader(new FileReader("read.txt"));//使用匿名对象读取文本
        int len=0;
        while((len=br.read())!=-1){
            System.out.println((char) len);

        }
        br.close();
    }
}
