What yellow highlighted code?

public abstract class ArgumentParser
{
   private String[] switchChars; // For example: "/", "-"
 
   private String[] switchSymbols; // Switch character(s)
 
   private Boolean caseSensitiveSwitches; // Are switches case-sensitive?
 
   // Domain of results when processing a command-line argument switch
   protected enum SwitchStatus { NoError, Error, ShowUsage };
 
   // Constructor that defaults to case-insensitive switches and 
   // defaults to "/" and "-" as the only valid switch characters

   // Constructor that defaults to "/" and "-" as the only valid switch characters

      : this(switchSymbols, caseSensitiveSwitches, new string[] { "/", "-" })
   {
   }
 
   // Constructor with no defaults
   protected ArgumentParser(String[] switchSymbols, Boolean caseSensitiveSwitches, String[] switchChars)
   {
   this.switchSymbols = switchSymbols;

1. You call the ArgumentParser(String[] switchSymbols) constructor, which
   
2. calls the ArgumentParser(String[] switchSymbols, Boolean caseSensitiveSwitches) constructor, passing in switchSymbols (from your call), false, and the string array { "/", "-" } as the parameters.
   
3. This constructor runs and returns control back to the constructor you called, which
   
4. runs any code contained in it's body (in this case, there isn't any.)
