import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
public class printlnt {
public static void maid(String args[]){
File filePath = new File("D:\\AB.txt");
BufferedReader br=new BufferedReader(new FileReader(filePath));
while ((String s = br.readLine()) != null) {
System.out.println(s + "\r\n");
}
}
}这样在最后两行还是有报错的。
////这样就OK了,你再试试....
import java.io.File;
import java.io.FileNotFoundException;

import java.io.IOException;
public class Printlnt {
public static void main(String args[]) throws IOException {
File filePath = new File("D:\\AB.txt");

while ((s = br.readLine()) != null) {
System.out.println(s + "\r\n");
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
////你上面的程序中main方法,你写成了maid,这样能编译也是不能运行的...
