How to enter arrays on the console humanly?

Question

Java

Hey!
there is an ordinary array: int[] array = {0,1,2,3};
if you enter on the console then output as a hash,
you have to use Array.toString
questions: 1. Why is the output displayed as a hash?
2. Why use Array.toString?
(in case of a two dimensional array Array.deepToString?)

Answer 1

Why is the output displayed as a hash?

Because the toString() method of the Object class is used, since arrays are inherited from it.
Not an Array, but an Array s . Because arrays don't have methods to output the contents as a string, you have to use the Arrays utility class.
