Tugas Pertemuan 13 : PBO

1. Tuliskan implementasi dari program kecil Abstract Class Makhluk hidup yang diwariskan kepada manusia, hewan, dan tumbuhan

Code LivingBeing.java :

public abstract class LivingBeing {
    private String name;
    public LivingBeing(String name) {
        this.name = name;
    }
    public String getName() {
        return name;
    }

    public abstract void breathe();
    public abstract void grow();
}

Code Human.java :

public class Human extends LivingBeing {
    public Human(String name) {
        super(name);
    }

    @Override
    public void grow() {
        System.out.println(getName() + " membutuhkan asupan nutrisi yang lengkap dan tercukupi untuk tumbuh.");
    }

    @Override
    public void breathe() {
        System.out.println(getName() + " bernafas dengan menghirup oksigen.");
    }
    public void speak() {
        System.out.println(getName() + " sedang berbicara dengan teman di sebelahnya.");
    }
}

Code Animal.java

public class Animal extends LivingBeing {
    public Animal(String name) {
        super(name);
    }
    @Override
    public void grow() {
        System.out.println(getName() + " berburu hewan-hewan kecil disekitarnya untuk bertahan hidup.");
    }
    @Override
    public void breathe() {
        System.out.println(getName() + " bernafas dengan menghirup oksigen.");
    }
    public void move() {
        System.out.println(getName() + " berlari dengan ke-empat kakinya.");
    }

}

Code Plant.java :

public class Plant extends LivingBeing {
    public Plant(String name) {
        super(name);
    }
    @Override
    public void grow() {
        System.out.println(getName() + " berkembang biak melalui penyerbukan pada bunganya.");
    }

    @Override
    public void breathe() {
        System.out.println(getName() + " bernafas dengan menghirup karbon dioksida pada siang hari dan menghirup oksigen pada malam hari.");
    }
    public void photosynthesize() {
        System.out.println(getName() + " melakukan fotosintesis untuk mendapatkan makanan.");
    }

}

Code Main.java

public class Main {
    public static void main(String[] args) {
        // Humans
        Human human = new Human("Agus");
        human.breathe();
        human.grow();
        human.speak();
        System.out.print("\n");
        // Animals
        Animal animal = new Animal("Kucing");
        animal.breathe();
        animal.grow();
        animal.move();
        System.out.print("\n");
        // Plants
        Plant plant = new Plant("Mawar");
        plant.breathe();
        plant.grow();
        plant.photosynthesize();
        System.out.print("\n");
    }
}

Output :

2. Pelajari dan baca simulasi Foxes and Rabbit yang ada di buku. Kemudian buat program perubahan dari struktur class umum menjadi bentuk Abstract Class.

Code Animal.java :

import java.util.Random;

public abstract class Animal {
    protected int x, y; // Koordinat posisi hewan
    protected Random random = new Random(); // Generator angka acak

    public Animal(int x, int y) {
        this.x = x;
        this.y = y;
    }

    public abstract void move(int gridSize);

    public abstract String toString();
}

Code Fox.java :

public class Fox extends Animal {
    public Fox(int x, int y) {
        super(x, y);
    }

    @Override
    public void move(int gridSize) {
        // Pilih gerakan acak: 0 = bawah, 1 = atas, 2 = kanan, 3 = kiri
        int direction = random.nextInt(4);
        switch (direction) {
            case 0 -> x = Math.min(x + 1, gridSize - 1); // Gerak ke bawah
            case 1 -> x = Math.max(x - 1, 0); // Gerak ke atas
            case 2 -> y = Math.min(y + 1, gridSize - 1); // Gerak ke kanan
            case 3 -> y = Math.max(y - 1, 0); // Gerak ke kiri
        }
    }

    @Override
    public String toString() {
        return "F";
    }
}

Code Rabbit.java

public class Rabbit extends Animal {
    public Rabbit(int x, int y) {
        super(x, y);
    }

    @Override
    public void move(int gridSize) {
        // Pilih gerakan acak: 0 = bawah, 1 = atas, 2 = kanan, 3 = kiri
        int direction = random.nextInt(4);
        switch (direction) {
            case 0 -> x = Math.min(x + 1, gridSize - 1); // Gerak ke bawah
            case 1 -> x = Math.max(x - 1, 0); // Gerak ke atas
            case 2 -> y = Math.min(y + 1, gridSize - 1); // Gerak ke kanan
            case 3 -> y = Math.max(y - 1, 0); // Gerak ke kiri
        }
    }

    @Override
    public String toString() {
        return "R";
    }
}

Code FoxesAndRabbitsSimulations.java :

import java.util.ArrayList;
import java.util.List;

public class FoxesAndRabbitsSimulation {
    private static final int GRID_SIZE = 5; // Ukuran grid
    private static final int NUM_RABBITS = 3; // Jumlah kelinci
    private static final int NUM_FOXES = 3; // Jumlah rubah
    private List<Animal> animals = new ArrayList<>();

    public void initialize() {
        // Tambahkan kelinci
        animals.add(new Rabbit(0, 0));
        animals.add(new Rabbit(1, 1));
        animals.add(new Rabbit(2, 2));

        // Tambahkan rubah
        animals.add(new Fox(3, 3));
        animals.add(new Fox(4, 4));
        animals.add(new Fox(0, 4));
    }

    public void simulate(int steps) {
        for (int step = 1; step <= steps; step++) {
            System.out.println("Step: " + step);
            String[][] grid = new String[GRID_SIZE][GRID_SIZE];

            // Kosongkan grid
            for (int i = 0; i < GRID_SIZE; i++) {
                for (int j = 0; j < GRID_SIZE; j++) {
                    grid[i][j] = ".";
                }
            }

            // Gerakkan hewan secara acak
            for (Animal animal : animals) {
                animal.move(GRID_SIZE);
                grid[animal.x][animal.y] = animal.toString();
            }

            // Cetak grid
            for (int i = 0; i < GRID_SIZE; i++) {
                for (int j = 0; j < GRID_SIZE; j++) {
                    System.out.print(grid[i][j] + " ");
                }
                System.out.println();
            }
            System.out.println();
        }
    }

    public static void main(String[] args) {
        FoxesAndRabbitsSimulation simulation = new FoxesAndRabbitsSimulation();
        simulation.initialize();
        simulation.simulate(5); // Jalankan 5 langkah simulasi
    }
}
