Code containing duplicate String literals can usually be improved by declaring the String as a constant field.
    
		
		
		    
		    
    		    
    		    
    		    

    		    This rule is defined by the following Java class:
    		    net.sourceforge.pmd.rules.strings.AvoidDuplicateLiteralsRule
    		    
		    
	    
	    
        
        
        Example:
            
                    

public class Foo {
 private void bar() {
    buz("Howdy");
    buz("Howdy");
    buz("Howdy");
    buz("Howdy");
 }
 private void buz(String x) {}
}
