What is the "length" in the char[]?

Question

char[] name = "VIKKYHACKS".toCharArray();
System.out.println(name.length);

In this program what is the "length" , If it were (new String("VIKKYHACKS")).length() then the length would be a method. But char[] is a datatype and cannot have fields or methods inside it. How does the second line of that program work ???

Answer 1

char[] is not a primitive data type. it is an Object, and it has a public field 'length'.

That is a good start.

Because Arrays are Objects, they have all the other items, like an equals() and hashCode() method too. (as well as all the treats like notify(), wait(), etc.)
