java - 使用类声明用整数和字符串填充数组

Question

因此，我不确定在根据我最初声明的已建立数组打印数组时缺少哪一步。我知道 java 有其他方法来打印数组，但我试图使步骤更长(而不是使用 Java 快捷方式)，以便更容易将相同的方法应用于其他语言。如果有人可以看看我所拥有的并告诉我我缺少什么，我将不胜感激。

更新:我觉得很愚蠢，因为这是一个简单的解决方案，但现在我正在处理另一个问题。我需要数组来接受字符串和整数，因此我创建了一个包含公共(public)类型单词和数字的类，但我不确定如何正确填充数组。我知道我没有设置数字来填充数组，但如果有人可以帮助我找出一个，我可以自己做另一个。

   package employeetotalhours;

 import java.util.ArrayList;

 public class employeetotalhours {  // main class declaration

public static class Table{          // sub class declaration
    public int number;      // establish input field values for ints
    public String word;     // establish input field values for strings
    Object array[];
}

public static void main(String[] args){ // main method  

Table[] table = new Table[9];

Table word = null;

table[0] = word;

ArrayList<Table> Table = new ArrayList<Table>();

Table.add(new Table());

 //         {{"Employee ","Su","M","T","W","T","F","Sa","Total"}, 
 //         {"EmpID 0       ","4 ","2","5","3","4","5","8 ", "0"}, 
 //         {"EmpID 1       ","1 ","7","8","4","3","3","4 ", "0"}, 
 //         {"EmpID 2       ","2 ","3","3","4","3","3","2 ", "0"}, 
 //         {"EmpID 3       ","3 ","3","3","7","3","4","1 ", "0"}, 
 //         {"EmpID 4       ","1 ","3","2","4","3","6","3 ", "0"}, 
 //         {"EmpID 5       ","5 ","3","4","4","6","3","4 ", "0"}, 
 //         {"EmpID 6       ","8 ","3","7","4","8","3","8 ", "0"}, 
 //         {"EmpID 7       ","2 ","6","3","5","9","2","7 ", "0"}};
    // all array data, multiple lines can be used as long as code is not closed with ;

    int rows = 9; // establish array row size

    int columns = 9; // establish array column size

    for(int i = 0; i < rows; i++)
    {
        for(int j = 0; j < columns; j++)
        {
            System.out.print(table[i] + " ");
        }
            System.out.println();
    }
}
}

在打印所有值的循环之前，有以下循环:

for(int i = 0; i < rows; i++) // loop to cycle through cells in array table
    for(int j = 0; j < columns; j++)
        array[i][j] = 0;

在此循环中，您将数组的每个元素设置为 0。
所以当你打印元素时，一切都是0
