Converting string to two dimensional array?

Question

Java

There is a line like 1233\n2345\n3467\n5677.
This string needs to be converted to String [4][4].direct to the true path......how to do it?

Answer 1

String str = "1233\n2345\n3467\n5677";
String[] arr= str.split("\n");
System.out.println(Arrays.toString(arr));

If you need character arrays, then for each element of the resulting array:
char[] charArray = str.toCharArray();
