为什么java中的toString方法似乎不适用于数组

I want to convert a character array to a string object using the toString() method in java. Here is a snippet of the test code I used:

import java.util.Arrays;
class toString{
    public static void main(String[] args){
        char[] Array = {'a', 'b', 'c', 'd', 'e', 'f'};
        System.out.println(Array.toString());
        }
}

In principle, it should print abcdef, but it is printing random gibberish of the likes of [C@6e1408 or [C@e53108 each time the program executes. I don't need an alternative out of this but want to know why this is happening.

To get a human-readable toString(), you must use Arrays.toString(), like this:

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

Java's toString() for an array is to print [, followed by a character representing the type of the array's elements (in your case C for char), followed by @ then the "identity hash code" of the array (think of it like you would a "memory address").

This sad state of affairs is generally considered as a "mistake" with java.

See this answer for a list of other "mistakes".
