在具有不同数据类型的 java 中初始化二维数组

Question

I want to initialize a 2d array in java which can hold different data types like char, int etc. My 2d array would be something like this -

  1 2 3 4 5 6 7
1 S S S S S S S
2 S S S S S S S
3 S S S S S S S
4 S S S S B S S
5 S S S S S S S
6 S S S S S B S
7 S S S S S S S

There is a space before 1 and I want to include that in my array.If I can initialize that, how can I do that? Do I use ASCII convention while inputting the string values or something? Please help. Note - I don't want to print the matrix, I will input these values manually.

Answer 1

I see two solutions if you want to use a single primitive type in the array, either treat the numbers as characters so you can have an array of char

char[][] array2d = new char[8][8]

or simply ignore the numbers and only include the characters and deduct the right number from the index (x,y) in the array

char[][] array2d = new char[7][7]

so for array2d[3][5] the numbers would be 4 and 6
