What are some obscure examples of a char value?
char Test = 'p';
char Test2 = 23;
I'd like to know how wierd this data type can look on an exam question....

The following ones are valid too...
char uni = '\u0065';
char hex = 0x65;
char oct = 056;
but
char lf = '\u000a';
is not valid because this is actually a linefeed which is translated as a real linefeed in a very early stage during the parsing and the line ends up looking like
char lf = '
';
which is clearly not a valid Java statement.

I am not sure if I exactly got what u are asking. But if u want to know what kind of values char datatype can hold...
Here are some,
char c;
Acceptable Values : Character Literals,Integer Literals which are within the range of values a char can hold
c='a';
c=0;
c=65535;
c=07;
c=0x07;
c='\u0061';
char c\u0061='\u0061';
Not acceptable:
c=-1; out of range for char
c=65536; out of range for char
