如何在读入txt文件行为空的情况下终止循环
Java code

import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;


public class Temp
{
    public static void main(String args[]) throws FileNotFoundException
    {
        Scanner in = new Scanner(new File("d:\\test.txt"));
        System.out.println("杨臣刚 - 老鼠爱大米");
        for(int i = 1; i <= 2; i++)//有两行歌词,怎么改写才能终止任意行的循环?
        {    
                String lyric = in.nextLine();
                System.out.println(lyric);
        }
    }
}
