怎么用java读取txt文件,我的文件中是字母为什么读出的是数字?
不要太复杂看不懂啊
我做的
import java.io.*;
public class Test{
public static void main(String[] args){
try{
FileInputStream s = new FileInputStream("s.txt");
BufferedReader b = new BufferedReader(new InputStreamReader(s));
while (b.read() != -1){
System.out.println(b.read());
}
}
catch (IOException e){
System.out.println("文件操作错误："+e.toString());
}
}
}
s.txt 里是字母 怎么打出来是数字? 还有-1
