TypeScript:

	class Urun
	{
	constructor(public ad: string)
	{
	}

	satinAl(adet: number = 0)
	{
	console.log(`${adet} adet ${this.ad} alındı.`);
	}
	}

	class Film extends Urun
	{
	constructor(ad: string)
	{
	super(ad);
	}

	satinAl(adet = 10)
	{
	console.log("Film stoklarda...");
	super.satinAl(adet);
	}
	}

	class Kitap extends Urun
	{
	constructor(ad: string)
	{
	super(ad);
	}

	satinAl(adet = 20)
	{
	console.log("Kitap stoklarda...");
	super.satinAl(adet);
	}
	}

	let matrix = new Film("Matrix");
	let seker: Urun = new Kitap("Şeker Portakalı");

	matrix.satinAl();
