UnnecessaryCaseChange


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");
  }
 }
