要是录入字符串 改哪里

1.导包 2.Scanner sc = new Scanner（System.in）；3 String s = sc.nextLine();

Scanner sc = new Scanner(System.in);
String line = sc.nextLine();

import java.util.Scanner;
Scanner sc = new Scanner(System.in);
String s = sc.next();

改为String,第二部也要改。。。

Scanner input = new Scanner(System.in);
String str=input.next();

把int改为String

把int改成String
