If a char array is an Object in Java, why does printing it not display its hash code?

Question

Printing a char array does not display a hash code:

class IntChararrayTest{
    public static void main(String[] args){
        int intArray[] = {0,1,2};
            


        

Answer 1

System.out is PrintStream which has a special method for char[] arg

public void println(char x[]) {
    synchronized (this) {
        print(x);
        newLine();
    }
}

int[] is printed via this method

public void println(Object x) {
    String s = String.valueOf(x);
    synchronized (this) {
        print(s);
        newLine();
    }
}
