SimplifyStartsWith
Since it passes in a literal of length 1, this call to String.startsWith can be rewritten using String.charAt(0) to save some time.
      
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
    
//PrimaryExpression
 [PrimaryPrefix/Name
  [ends-with(@Image, '.startsWith')]]
 [PrimarySuffix/Arguments/ArgumentList
  /Expression/PrimaryExpression/PrimaryPrefix
  /Literal
   [string-length(@Image)=3]
   [starts-with(@Image, '"')]
   [ends-with(@Image, '"')]
 ]
 
            
  
		    
		    
	    
	    
        
        
        Example:
            
                    
  
public class Foo {
  boolean checkIt(String x) {
      return x.startsWith("a");
  }
}
