System.out.println(numbers); // Invokes println(Object)
}
}
To summarize, char arrays are not strings. To convert a char array to a string, invoke
String.valueOf(char[]) . Some library methods do provide stringlike support for char arrays,
typically having one overloading for Object and another for char[] ; only the latter has the desired
behavior.
The lesson for language designers is that the char[] type should probably have overridden
toString to return the characters contained in the array. More generally, the array types should
probably have overridden toString to return a string representation of the contents of the array.
