What does the program print?

JAVA

public class Main {
    static int count;
    static boolean ready;
    public static void main(String[] args) {
        System.out.print(count);
        System.out.print(" ");
        System.out.println(ready);
    }
}

0 false

Expecting a compile error: only local variables must be assigned before a read; fields such as count and ready get default values.
Expecting 0 0, as in languages where false is a number: a Java boolean defaults to false and prints as false.

What default value does a char field get?
Why does a local variable get no default value?
