public class ClassTest {
char c1='\'';
//1 char c2='\ucafe';
//2 char c3='\ucfe';

}
c2,c3 variables are unicode characters .But why line 2 only shows compilation error.
Please explain?

[Maurizio Nagni]

if the code is as you typed here it should be

 char c1='\';

not with the double ----> ' <------ like in your code

char c1='\'';

char c2='\ucafe';
char c3='\ucfe';

'\ucfe' is a invalid unicode , Unicode must consits of 4characters after \u
Each of the 4 characters must be valid hexadecimal number [0-9,a-f]
\uFFFG is invald, because FFFG is not unicode.
Hope this clears.
Thanks

A valid unicode is represented in java as
\uxxxx and not \Uxxxx
here xxxx ranges from 0000 to ffff
and xxxx [4digits] is a hexadecimal number.
