Java arrays printing out weird numbers and text [duplicate]

Answer 1

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

The current output is classtype@hashcode.

Incase you need to print arrays with more than one dimension use:

Arrays.deepToString(arr);

Also remember to override toString() method for user-defined classes so that you get a representation of the objet as you choose and not the default represention which is classtype@hashcode
