Fix the compiler error by making the HolaWorld's sayHelloTo method properly override the sayHelloTo method in the HelloW

I think I get what the task is asking (newbie) but unsure of how to layout the code? any ideas

HelloWorld.java 
public class HelloWorld {
  private String programmingLanguage;

  public HelloWorld() {
    programmingLanguage = "Java";
  }

  public void sayHelloTo(String name) {
    System.out.printf("Hello, %s%n!", name);  
  }
}
HolaWorld.java 
public class HolaWorld extends HelloWorld {
  @Override
  public void sayHelloTo() {
    String name = "";
    System.out.printf("Hola, %s%n!", name);
  }
}

In HolaWorld.java you want to make sure that sayHelloTo() accepts the same parameters as the method in HelloWorld.java.

If you look at the two methods you can see that they differ a bit.

Try changing sayHelloTo() in HolaWorld.java to match the one in HelloWorld.java and see what happens.

I changed the method in the holaworld to match it with the on i the helloworld . i also removed String name = ""; because it has been declare already . this is my code below HolaWorld.java public class HolaWorld extends HelloWorld { @Override public void sayHelloTo(String name) { System.out.printf("Hola, %s%n!", name); } }
