String字符串转换成char数组

String字符串转换成为char数组

用ArrayList数组

package java11_18;

import java.util.ArrayList;
import java.util.Scanner;

public class java_1118 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		String s;
		Scanner input=new Scanner(System.in);
		s=input.next();
		System.out.println(toCharacterArray(s));
	}
	public static ArrayList<Character> toCharacterArray(String s)
	{
		ArrayList<Character> list=new ArrayList<Character>();
		for(int i=0;i<s.length();i++)
		{
			list.add(s.charAt(i));
		}
		return list;
	}

}
