I'll declare a String that I'll name s.…And I'll try to assign it to the keyword Null.…Now, I'll intentionally misspell it.…The keyword Null in Java is all lower case.…When I type it with an upper case in,…and then I try to run the application,…the application doesn't even compile.…Instead I get a syntax error,…telling me that the compiler can't find the symbol.…It means this keyword Null.…And it tells me exactly where the problem is…and how to deal with it.…
