char initial value in Java

Question

You initialize an int variable defined within a method to have a value of 0 until you compute specific values for the int. What can on

Answer 1

Either you initialize the variable to something

char retChar = 'x';

or you leave it automatically initialized, which is

char retChar = '\0';

an ascii 0, the same as

char retChar = (char) 0;

What can one initialize char values to?

Sounds undecided between automatic initialisation, which means, you have no influence, or explicit initialisation. But you cannot change the default.
