如何在Java的一行中输入多个字符串

Question

我想知道如何使用JAva的Scanner类读取包含多个String单词的行。

Answer 1

There is no specific way to do that. Anyway you can provide comma separated strings as below example.

public static void main(String args[]){
    Scanner in = new Scanner(System.in);
    String str = in.nextLine();
    String[] strArr = str.split(",");
    for(String s: strArr){
        System.out.println(s);
    }
}  

Answer 2

write a method like this:

function String reader(Scanner s, int lines){
    String ret = "";
    for(int i = 0; i < lines; i++)
        ret += s.nextLine();
    return ret;
}

and use it like this:

Scanner s = new Scanner(System.in);
String threeLines = reader(s, 3);

It's just a for loop that loops and read multiple lines
