如何用字符串填充我的二维数组？ Java

I am using Arrays.fill() for integers but i dont know how to fill with string. I want it to look like this on the terminal screen:

AAA

Answer 1

One immediate solution I can think of is using Java Streams.

String[][] table = new String[3][3];
Arrays.stream(table).forEach(strings -> Arrays.fill(strings,"A"));

It will give you output

[A, A, A]
[A, A, A]
[A, A, A]

To Print You can use

Arrays.stream(table).forEach(strings -> System.out.println(Arrays.toString(strings)));
