999 Pointsnon-static method getCowName() cannot be referenced from a static context
I am trying to call Cow.getCowName() from Main.java (within the main method). and get this error. Here's Cow.java
class Cow { private final String name;
public Cow (String name) { this.name = name; }
public String getCowName() { return name; } }
Here's Main.java import java.io.Console; public class Main {
public static void main(String[] args) { Console console = System.console();
Cow cow = new Cow("Larry");
System.out.printf("The new Cow's name is %s",
Cow.getCowName());
}
} I googled it and got this answer - A non-static method is dependent on the object. It is recognized by the program once the object is created. But a static method can be called before the object creation. Hence you cannot make the reference.
Which I get the gist of but what constitutes calling a method from a non static context? How do I fix my code so I am not doing that? The only thing I can think of is that it's within the main method which is indeed static but I called a bunch of methods precicely like this in the hangman project and got no problems.
Can someone clarify this for me please?

Just fix the spelling:
cow.getCowName());
