UnnecessaryCaseChange
Using equalsIgnoreCase() is faster than using toUpperCase/toLowerCase().equals()
       

		
		
		    
		    
    		    
    		    
    		    

    		    
This rule is defined by the following Java class:
    		    net.sourceforge.pmd.rules.strings.UnnecessaryCaseChange
    		    
		    
	    
	    
        
        
        
Example:
            
    
                
                 
 public class Foo {
  public boolean bar(String buz) {
    // should be buz.equalsIgnoreCase("baz")
    return buz.toUpperCase().equals("baz");
    // another unnecessary toUpperCase()
    // return buz.toUpperCase().equalsIgnoreCase("baz");
  }
 }
