Java auto-intalize primitive variables in Java 8

I'm trying to learn Java 8 (moving from C -> Java). I tried:

public class Test {
       public static void main(String[] args){
       int i;
       System.out.println(i);
       }
}

Gives a compiler error saying the variable "i" has not been initialized. I thought that one of the nice things about Java was that it would auto-initialize primitives to a default value.

Nope. You must assign values to local variable before deferencing. – Boris the Spider Feb 02 '18 at 21:44
"it would auto-initialize primitives to a default value" that happens for class fields, not for local variables. – Pshemo Feb 02 '18 at 21:48
