Fix: java: void cannot be dereferenced

public class Example {
    
    static void sayHello() {
        System.out.println("Hello!");
    }

    public static void main(String[] args) {
        sayHello().toString();
    }

}

As you can see we get an error "void cannot be dereferenced" when we try to access a member on a void type. In the above example sayHello() returns void and we are trying to access toString()
