								In a < code > switch< / code >  statement you may not be able to specify all possible values as < code > case< / code >  statements. Instead, you can add the < code > default< / code >  statement which will be executed if no matching < code > case< / code >  statements are found. Think of it like the final < code > else< / code >  statement in an < code > if/else< / code >  chain.
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							 
							
							
								A < code > default< / code >  statement should be the last case.
