接口的繼承

interface Person {
    fname: string;
    age: number;
    eat():void
}

// 通過extends實現(xiàn)接口的繼承
interface WorkerMan extends Person {
    profession: string;
    yearsOfWork: number;
    coding():void
}



// 繼承出來的接口，用于約束類
class WorkerPerson implements WorkerMan {
    fname: string;
    age: number;
    profession: string;
    yearsOfWork: number;
    constructor (f:string, a:number, p:string, y:number) {
        this.fname = f;
        this.age = a;
        this.profession = p;
        this.yearsOfWork = y;
    }

    eat() {

    }

    coding() {

    }
}

類既可以被接口約束，還可繼承其他的類

類可與繼承其他類，但依然會被接口約束

interface Person {
    fname: string;
    age: number;
    eat():void
}

// 通過extends實現(xiàn)接口的繼承
interface WorkerMan extends Person {
    profession: string;
    yearsOfWork: number;
    coding():void
}

// 某個類，即可被接口約束，還可稱為超類的子類
class Home {
    address:string;
    constructor(addre:string) {
        this.address = addre;
    }
}

// 繼承于其他類，還可被接口約束
class WorkerPersonHome extends Home implements WorkerMan {
    fname: string;
    age: number;
    profession: string;
    yearsOfWork: number;
    constructor (f:string, a:number, p:string, y:number, ad:string) {
        super(ad); // 
        this.fname = f;
        this.age = a;
        this.profession = p;
        this.yearsOfWork = y;
    }

    eat() {

    }

    coding() {

    }
}
