      // Four basic data types:
      int nStudents = 51;
      double avgGrade = 88.3;
      char finalGrade = 'A';      // Single quote required
      boolean funClass = true;    // true and false are reserved words

      // The following line will cause an error. (Uncomment it to see!)
      //      int y = 5.0; 
      // But this one is okay: (Why?)
      double myGrade = 90;

      // Strings are also useful:
      String myName = "Kiri";
      // You can add them together (concatenation)
      // Don't forget to add spaces where needed
      String myFullName = "Kiri" + " Wagstaff";

      // What if you want to put weird stuff in the string?
      // Use backslash (\) to "escape" characters
      // Double quote means 'end of string'; '\' changes the meaning.
      String fancyName = "Kiri \"Lou\" Wagstaff";
      // This works for characters, too
      char quote1 = '\'';
      // But since chars use single quotes, this doesn't need a \:
      char quote2 = '"';
      // Likewise, single quote does not need to be escaped in a string:
      String quoteString = "This is a single quote: ' ";
