Hi, Can anyone explain why I get an Invalid character constant error with the following line of code //char a = '\u000A'; + Why does the above not compile but the following does /*char a = '\u000A';*/ Any help would be truly appreciated Tony
Tony, Please re-register with a UserName that conforms to the JavaRanch Naming Policy. Thanks for your cooperation. Unicode literals are translated very early on in the compilation process. '\u000A' happens to be the line feed and the result is that the compiler tries to compile <pre> // char a = ' '; not good because // is only for one line
/* char a = ' '; */ OK because /* */ spans lines </pre>

If you look at the Unicode Charts yout will see that \u000A is unicode for Line Feed. Since the .java file is parsed before compiling, and all of the unicode literals are converted first, the input line is actually split into 2 lines by the LF. Then as Junilu said, the // comment syntax does not include both of those lines.
