when converting a string to a string array during splitting, it produces an undesired output

Question

When i try to split a String "Element" into a String array, and then print out the result i get an output which i don't understand. My code is as follows:

String element = mapArray.get(i);
elementSplit = element.split("(?!^)");
System.out.println(elementSplit);

And the output produced when i print the String Array is:

[Ljava.lang.String;@3dee2310

Could someone please advise, as i do not know why it is printing this output.

Thanks very much

Use `Arrays#toString()` method to print an array. – Rohit Jain Feb 13 '14 at 16:04 — Rohit Jain, Feb 13 '14 at 16:04

You have to use Arrays.toString method.

System.out.println(Arrays.toString(elementSplit));

Due to speed You should use toCharArray method instead of split("(?!^)") and in order to print array you should use Arrays.toString method

String element = mapArray.get(i);
elementSplit = element.toCharArray();
System.out.println(Arrays.toString(elementSplit));
