java - 此代码的问题(抱歉，我不能具体说明)

Question

尝试编写一个程序，将 char 数组 (ch) 的值从 65 分配到 90。然后我尝试像这样打印:

    A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z

我试图用两个循环来做这件事，但遇到了很多麻烦。这是我到目前为止所拥有的:

    import java.util.*;
    public class Lab10a {
        public static void main(String[] args) {
            char ch[] =new char[26];
            for (int x = 0; x < ch.length; x++){
                ch[x] = (char)(x + 65);
                for(int i = 0, i < ch.length; i++)[


                }
            }
     //It doesn't need to be converted to a string here, this is just a method i tried.
                System.out.println(Arrays.toString(ch) + ", ");
        }
    }

这是我目前得到的打印输出:

    [A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z], 

抱歉，我的编码太不清楚了，真的不太确定如何去做。建议？

Answer 1

String out = "";
for (int i = 0; i < ch.length; i++)
     out += ", " + ch[i];
System.out.println(out.subString(2));
