PART 1: GETTING STARTED

Create a new Java Project.

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 boolean evergreen;// true if evergreen

// false if deciduous

// CONSTRUCTORS

public Tree()

{

name = "";

age = 0;

evergreen = true;

}

// you fill this one

public Tree (String n, int a, boolean e)

{

// PUT YOUR CODE HERE

}

Page Break

// GETTERS (accessors) and SETTERS (mutators)

public String getName()

{

return name;

}

public int getAge()

{

// PUT YOUR CODE HERE

}

// PUT YOUR METHOD getEvergreen() HERE

public void setName(String s)

{

name = new String(s);

}

public void setEvergreen(boolean e)

{

// PUT YOUR CODE HERE

}

// PUT YOUR METHOD setAge() HERE

// OTHER METHODS

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;

}

}

another question:

Create a SEPARATE class in a SEPARATE file within the same project. Call it Lab5 and enter this code. You do not have to type in the comments.

/*

* This program tests the Tree class

*/

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());

}

}

PART 2: WRITING CLASS METHODS

Fill in the code for the second constructor.

Fill in the code for the getAge() method.

Write the entire getEvergreen() method, including the header.

Fill in the code for the setEvergreen() method.

Write the entire setAge() method, including the header.
