Split a string into array without empty element

Question

Attempting to split a string into separated letters

String string1 ="KKXGJRNQGA";
List<String> solutionArray = Arrays.asList(string1.split(""));

will return [, K, K, X, G, J, R, N, Q, G, A] before each alphabet a space and at [0] is an empty element.
But actually i want is [K,K,X,G,J,R,N,Q,G,A], is there a way to solve it? can using regex match?

Using string1.split("") will return an empty first value.

Use toCharArray() which converts the string to a new character array.

"KKXGJRNQGA".toCharArray()

or a simple regular expression

String s = "KKXGJRNQGA";
String[] p = s.split("(?!^)");
System.out.println(Arrays.asList(p));

Output:

[K, K, X, G, J, R, N, Q, G, A]

... and you can change that to a List or to Strings later (or ideally use as is).
