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

Typically for local variables I initialize them as late as I can. It's rare that I need a "dummy" value. However, if you do, you can use any value you like - it won't make any difference, if you're sure you're going to assign a value before reading it.

If you want the char equivalent of 0, it's just Unicode 0, which can be written as

char c = '\0';

That's also the default value for an instance (or static) variable of type char.
