StringBuffer sb = new StringBuffer('c'); The
char will be converted into int to intialize
StringBuffer size.

Literal
  [starts-with(@Image, "'")]
  [ends-with(@Image, "'")]

            
  
		    
		    
	    
	    
        
        
        Example:

  StringBuffer sb1 = new StringBuffer('c'); //Bad
