Java控制台输入带空格的字符串,读取的时候只要按照行来读取,就可以获取到输入的空格,下面是示例:/**按行读取 */import java.io.*;public class SystemInTest {public static void main(String[] args) { BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));//建立从控制台输入的类 String str; try { str = stdin.readLine();//读取一行 System.out.println(str); } catch (IOException e) { e.printStackTrace(); } }}
