Strange toCharArray() behavior

Question

I was experimenting with toCharArray() and found some strange behavior.

Suppose private static final char[] HEX_CHARS = \"0123456789abcdef\".toCha

Answer 1

Arrays are objects, and its toString methods returns

getClass().getName() + "@" + Integer.toHexString(hashCode())

In your case [C@19821f means char[] and @19821f is its hashcode in hex notation.

If you want to print values from that array use iteration or Arrays.toString method.

`System.out.println(Arrays.toString(HEX_CHARS));`
