Shape

Buatlah class Shape. class memiliki dua field String: name dan size. class mempunyai method printShapeInfo, dimana hanya mengeluarkan nilai name dan field size dari object Shape. Juga memiliki method printShapeName dan printShapeSize, dimana mencetak nama dan size dari object, berturut-turut.

Menggunakan pewarisan, buat class Square dengan field yang sama dan method seperti itu dari class Shape. Class ini mempunyai dua tambahan field integer: length dan width. Method printShapeLength dan printShapeWidth yang mencetak panjang dan lebar object yang juga termasuk dalam class ini. Anda juga harus meng-override printShapeInfo untuk mencetak keluaran field tambahan dalam subclass juga.

square persegi = new square("persegi");

Shape bentuk = persegi;

persegi.length = 37;

persegi.width = 15;

persegi.printShapeName();

persegi.printLength();

persegi.printWidth();

persegi.printShapeSize();

System.out.println("\n");

System.out.println("Hasilnya adalah..");

persegi.printShapeInfo();

Binatang

Buatlah interface Animal yang mempunyai 2 method:eat dan move. Semua method ini tidak punya argumen atau nilai return. Method ini hanya mengeluarkan bagaimana object Animal makan dan bergerak. Sebagai contoh, seekor kelinci memakan wortel dan bergerak dengan melompat. Buat class Fish dan Bear yang menggunakan interface Animal. Terserah kepada Anda bagaimana menggunakan method eat dan move.
