Question

PART 1: GETTING STARTED 1. Create a new Java Project. 2. Create a new Tree class and enter this code. You do not have to type in the comments public class Tree { private String name; private int age; private bogJsAn evergreen; // true if evergreen // false if deciduous //CONSTRUCTORS public Tree( { name 0; evergreen = true; age } // you fill this one public Tree (String n, jnt a, bgalean e) //PUT YOUR CODE HERE }

Answer 1

class Tree {
   private String name;
   private int age;
   private boolean evergreen;

   public Tree() {
       name = "";
       age = 0;
       evergreen = true;
   }

   public Tree(String n, int a, boolean e) {
       name = n;
       age = a;
       evergreen = e;
   }

   public String getName() {
       return name;
   }

   public void setName(String aName) {
       name = aName;
   }

   public int getAge() {
       return age;
   }

   public void setAge(int aAge) {
       age = aAge;
   }

   public boolean getEvergreen() {
       return evergreen;
   }

   public void setEvergreen(boolean aEvergreen) {
       evergreen = aEvergreen;
   }

   public String toString() {
       String s = "This " + name + " tree is " + age + " years old.";
       if (evergreen)
           s = s + " It stays green all year round";
       else
           s = s + " It loses its leaves in the fall";
       return s;

   }
}

public class Lab5 {
   public static void main(String[] args) {
       Tree oak = new Tree();
       oak.setName("Oak");
       oak.setAge(10);
       oak.setEvergreen(false);
       System.out.println(oak);

       Tree pine = new Tree("Pine", 15, true);
       System.out.println(pine.getName());
       System.out.println(pine.getAge());
       System.out.println(pine.getEvergreen());
       System.out.println(pine.toString());

   }
}
