java - 需要有关编译器错误的帮助

Question

import java.util.Scanner;

public class EnemyMessage {

    public static void main(String[] args) {
        System.out.println("enter the code:");
        Scanner keyboard = new Scanner(System.in);
        int key;
        int i;
        String code = keyboard.next();
        for (key = 1; key <= 100; key++) {
            for (i = 0; i < code.length(); i--) {
                char c = code.charAt(i);
                int n = (int) c;
                System.out.println(n);
                {
                    (char) c = (int) c - 32 + key + 127;
                    System.out.println(c);
                }
            }

        }
    }
}

这段代码给了我两个对我来说没有多大意义的错误。据我所知，我没有做任何与我之前所做的不同的事情。

错误:

错误的构造函数

Answer 1

import java.util.Scanner;
public class EnemyMessage
{

    public static void main (String[] args)
    {
        System.out.println("enter the code:");
        Scanner keyboard = new Scanner (System.in);
        int key;
        int i;
        String code = keyboard.next();
        for (key = 1; key<=100; key++)
        {
        for ( i = 0; i < code.length(); i--)
        {
            char c = code.charAt(i);
            int n = (int)c;
            System.out.println(n);
            { 
            c = (char)(c - 32 + key + 127);
            System.out.println(c);
            }
        }

    }
   }
}
