Abstract

This method fails to override a similar method in its superclass because their parameter lists do not match.

Description

This method declaration looks like an attempt to override a method in a superclass, but the parameter lists do not match, so the superclass method is not overridden.

Examples

The class DeepFoundation is meant to override the method getArea() in its parent class, but the parameter lists are out of sync.

	public class Foundation
	{
	  public int getArea() {
		...
	  }
	}
	
	class DeepFoundation extends Foundation
	{
	  public int getArea(int a) {
		...
	  }
	}
