推荐答案

这是一个简单的代码段，请阅读键盘，直到按下Enter键为止.

Here is a simple snippet, reading the keyboard until the Enter-button is hit.

import java.io.*;


class MyClass

{
	public static void main(String[] args) throws IOException{

		//define String for input
                 String Read= ""; 
		
		//instantiate InputStreamReader for Textstream
		InputStreamReader Reader= new InputStreamReader(System.in);

                //instantiate BufferedReader for buffering the stream
		BufferedReader BufferedIn= new BufferedReader(Reader);

		//while Enter is not hit, the input stream is read from keyboard
                Read= BufferedIn.readLine();
			
			
			
		}
	}
}
