这段代码有点熟悉，但是太久没有练习了。
import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

public class MyReader {

public static void main(String[] args) {
    File me = new File("src/MyReader.java");
    BufferedReader br = null;
    FileReader fr = null;
    try {
        fr = new FileReader(me);
        br = new BufferedReader(fr);
        String tmp = null;
        while ((tmp = br.readLine()) != null) {
            System.out.println(tmp);
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            br.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            fr.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

}
