char c = '\u0000';
When I print c, it shows ‘a’ in the command line window.
So what’s the default value of a char type field?
Someone said '\u0000' means null in Unicode; is that right?
The default value of a
charattribute is indeed'\u0000'(the null character) as stated in the Java Language Specification, section §4.12.5 Initial Values of Variables .In my system, the line
System.out.println('\u0000');prints a little square, meaning that it’s not a printable character – as expected.
