Does a char variable have some default value? Like garbage value?

The default value for a char is a nul character -- which has an ascii value of zero.

It's '\0', or simply 0 (as an integer literal).

That is the default value for a field; all fields have default values of 0, which is interpreted as the null character for a char, false for a boolean, and null for all reference types.

Local variables and parameters do not have default values at all.
 
It is sorta covered in the JavaRanch Style Guide.
