java - java中数组中的不兼容类型

Question

我对java很陌生，对于作业，我必须要求三个单词，然后在数组中逐列垂直打印它们。我想我已经走了很远，但由于不兼容的类型问题，我无法打印数字。错误是针对 array[numb1][0]= word1.charAt(numb1); 给出的。 java 不接受 numb1，我该如何解决这个问题？

import java.util.Scanner;
import java.util.Arrays;
import java.lang.String;

public class assignment51
{
   static void main()
  {
      Scanner read=new Scanner(System.in);
      System.out.println("Please enter the first of three words:");
      String word1= read.nextLine();

      System.out.println("Please enter the second of three words:");
      String word2= read.nextLine();

      System.out.println("Please enter the third of three words:");
      String word3= read.nextLine();

      int count1 = word1.length();
      int count2 = word2.length();
      int count3 = word3.length();


      int [] nums = new int [] {count1,count2,count3};
      int max = 0;
      for (int i = 0;i<nums.length;i++)
      {
          if (nums[i] >max)
          {
              max=nums[i];
            }
        }      

        max=max-1;
      String [][] array=new String[max][2];

      for (int numb1 = 0; numb1<(count1-1); numb1++)
      {
          array[numb1][0]= word1.charAt(numb1);
  }

        for (int numb2 = 0; numb2<(count2-1); numb2++)
      {
          array[numb2][1]= (word2.charAt(numb2));
  }

        for (int numb3 = 0; numb3<(count3-1); numb3++)
      {
          array[numb3][2]= (word3.charAt(numb3));
  }


}
}

您正在尝试将一个字符分配给一个字符串。那是行不通的。在 Java 中，字符和字符串是完全不同的动物。

您的数组应声明为char[][]。
