public class Dog extends Animal { private String Name; private String Class; public void String (String Name,String Class) { this.Name=Name; this.Class=Class; } public static void main(String[]arg) { Dog c1=new Dog("冉冉 ","边牧"); } }

在这段代码中，`Dog` 类继承自 `Animal` 类，它有两个私有属性 `Name` 和 `Class`。`String` 方法不是一个合法的构造方法，因为构造方法的名称应该与类名相同，并且不应该有返回类型。如果你想要创建一个构造方法，应该像这样：

public Dog(String Name, String Class) {
    this.Name = Name;
    this.Class = Class;
}

在 `main` 方法中，你创建了一个 `Dog` 类的实例 `c1`，并传入了它的名字和类别。
