Java Collection - 如何
使用扫描器从用户输入填充字符数组

import java.util.Scanner;

public class Main {
  public static void main(String args[]) {
    Scanner sc = new Scanner(System.in);
    System.out.println("Please enter elements...");
    char[] a = sc.next().toCharArray();
    System.out.println("Array elements are : ");
    for (int i = 0; i < a.length; i++)
      System.out.println(a[i]);
  }
}
