String[] strArray = str.split(""); 

but this error occured.

Exception in thread "main" java.util.regex.PatternSyntaxException: Unexpected internal error near index 1

Answer 1

it should be

String[] strArray = str.split("");

the reason why is because in Regex, has special meaning so you need to escape it into \.

and in java, \ should be equal to ""
