,通过隐式转换,调用对应的方法转换 scala> implicit class Dog(val name: String){ | def bark=println(s"$name is barking...")} defined class Dog scala> "barkdo".bark barkdo is barking 2)注意事项: 隐式类的主构造函数参数有且仅有一个!...源类型与目标类型是一一对应的 scala> implicit class Dog2(val name: String, val age: Int){ | def bark=println(s"$name is barking
{ this.name = name; } public void bark() { System.out.println(name + " is barking...Dog dog1 = new Dog("Buddy"); Dog dog2 = new Dog("Max"); dog1.bark(); // 输出:Buddy is barking...dog2.bark(); // 输出:Max is barking } } 在上述示例中,name是一个实例成员变量,每个Dog对象都有自己独立的name变量。
breed: string) { super(name); this.breed = breed; } bark() { console.log(`${this.name} is barking
.'); } } class Dog extends Animal { Dog(String name) : super(name); barking() { print('Dog...is barking.'); } } 复制代码 多态 多态可以理解为相同的行为,不同的实现方式。
通过下面一个简单的类来理解下Java中的类的定义; public class Dog{ String breed; int age; String color; void barking...一个类可以拥有多个方法,在上面的例子中,barking()、hungry()、和sleeping()、都是Dog类的方法。
public class Dog extends Animal { public void bark() { System.out.println("The dog is barking...Dog对象 Dog dog = new Dog(); dog.eat(); // 输出:The animal is eating. dog.bark(); // 输出:The dog is barking
