Token Enumeration in Java

Question

I'm writing a lexer using jflex for a made up programming language. It requires an enumeration java class which holds a bunch of tokens for the made up language. Things like STRING_TKN, ON_TKN, GOTO_TKN, COMMAND_TKN, etc. I haven't used java in a while so I forget how to set these up.

Thanks

Answer 1

Java as an enum type.

An example:

public enum Colors{
    RED,BLUE,GREEN;
}
