+b. Explain why inheriting from Pokemon is useful +The Pokemon class contains general attributes that specific Pokemon classes can inherit from. This is useful because although different types of Pokemon are different, they all share common attributes that may become repetitive if the same code is rewritten for multiple classes. An example of how this is useful is how the attack method is overidden in the Jigglypuff and Pikachu classes. +``` java +@Override + void attack(Pokemon obj) { + obj.takeDamage(15); + } +``` +c. Explain an example of method polymorphism in your code +The attack method in the Pokemon class is defined with no additional code. The method override for the attack method in the Pikachu class uses the takeDamage method to specify a specific amount of damage dealt thats unique to the Pikachu class. +```java + @Override + void attack(Pokemon obj) { + obj.takeDamage(25); + } +``` +d. Explain an example of subtype polymorphism in your code +j and p are referenced to the Pokemon class but are instances of the Jigglypuff and Pikachu classes. This shows how Jigglypuff and Pikachu are subclasses of Pokemon. +```java +Pokemon j = new Jigglypuff(100, "Jigglypuff"); +Pokemon p = new Pikachu(100, "Pikachu"); +``` +e. Explain why you made one of your methods public +I made getName() public because its a getter method so its purpose is for outside classes to access the value of the private variable name. +```java + public String getName() { + return name; + } +``` +f. Explain why you made one of your instance variables private +I made the health variable private because the health should not be able to be modified from outside classes. It should only be used and changed in controlled ways, such as through methods in the class. +```java + private int health; +``` \ No newline at end of file diff --git a/Week4/Jigglypuff.java b/Week4/Jigglypuff.java new file mode 100644 index 0000000..01e5d8e --- /dev/null +++ b/Week4/Jigglypuff.java @@ -0,0 +1,13 @@ +package Week4; + +public class Jigglypuff extends Pokemon{ + // have jigglypuff attack its opponent + @Override + void attack(Pokemon obj) { + obj.takeDamage(15); + } + //constructor + Jigglypuff (int health, String name) { + super(health, name); + } +} diff --git a/Week4/Main.java b/Week4/Main.java new file mode 100644 index 0000000..90ac133 --- /dev/null +++ b/Week4/Main.java @@ -0,0 +1,21 @@ +package Week4; + +public class Main { + public static void main(String[] args) { + // create jigglypuff and pikachu objects + Pokemon j = new Jigglypuff(100, "Jigglypuff"); + Pokemon p = new Pikachu(100, "Pikachu"); + // have the pokemons attack each other until one collapses + while(!j.getIsFainted() && !p.getIsFainted()) { + j.attack(p); + p.attack(j); + } + // printing the winner + if (j.getIsFainted()) { + System.out.println("Pikachu won!"); + + } else { + System.out.println("Jigglypuff won!"); + } + } +} diff --git a/Week4/Pikachu.java b/Week4/Pikachu.java new file mode 100644 index 0000000..efe34b7 --- /dev/null +++ b/Week4/Pikachu.java @@ -0,0 +1,13 @@ +package Week4; + +public class Pikachu extends Pokemon{ + // have pikachu do damage to its opponent + @Override + void attack(Pokemon obj) { + obj.takeDamage(25); + } + // constructor + Pikachu (int health, String name) { + super(health, name); + } +} diff --git a/Week4/Pokemon.java b/Week4/Pokemon.java new file mode 100644 index 0000000..e9c5642 --- /dev/null +++ b/Week4/Pokemon.java @@ -0,0 +1,30 @@ +package Week4; + +public abstract class Pokemon { + //private instance variables + private int health; + private String name; + // constructor + Pokemon (int health, String name) { + this.health = health; + this.name = name; + } + // subtract health when taken damage + public void takeDamage(int damage) { + health -= damage; + } + // attack method + abstract void attack(Pokemon obj); + // check if pokemon collapsed + public boolean getIsFainted() { + if (health <= 0) { + return true; + } + else { + return false; + } + } + public String getName() { + return name; + } +}
