Question

如何从java控制台输入带空格的字符串？

Answer 1

1. /**按行读取 */import java.io.*;public class SystemInTest {
   public static void main(String[] args) {  BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));  String str;  try {   str = stdin.readLine();   System.out.println(str);  } catch (IOException e) {   e.printStackTrace();  }   }}
   

2. 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();  }   }}

3. import java.util.Scanner;
4. public class encode2013
5. {
6.     public static void main(String[] args){
7.         String inString;
8.         String delimiter;
9.         Scanner scan = new Scanner(System.in);
10.         inString=scan.nextLine();
11.         delimiter=scan.next();
12.         inString= inString.replace(" ",delimiter);
13.         System.out.println(inString);
14.     }
