UnnecessaryFinalModifier


UnnecessaryFinalModifier
When a class has the final modifier, all the methods are automatically final.
      
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
        
//ClassOrInterfaceDeclaration[@Final='true' and @Interface='false']
/ClassOrInterfaceBody/ClassOrInterfaceBodyDeclaration/MethodDeclaration[@Final='true']
    
              
  
		    
		    
	    
	    
        
        
        Example:
            
                    

public final class Foo {
    // This final modifier is not necessary, since the class is final
    // and thus, all methods are final
    private final void foo() {
    }
}
