System.out.println(buffer.readLine());
System.out.println(buffer.readLine());
}
catch(IOException e)
{
e.printStackTrace();
}
}
}
程序运行结果是：true
3.1415926
为什么System.out.println(buffer.readLine());和System.out.println(buffer.readLine());没有输出内容来啊？
楼主, 我运行了你的代码, 有内容输出啊. 结果为:
true
3.1415926
T h a t w a s P I
That was PI
我和二楼的运行结果一样啊
^_^,我也有输出呀
true
3.1415926
T h a t w a s P I
That was PI
我也试了 可以输出阿
搂主看看你有没有生成data.txt这个文件？
我的结果也同楼上,没问题啊!
我也运行了，前面两位都一样啊！
我的也有结果啊,和上面的一样啊
