Question

Modify the definition of the class Species in Listing 5.19 of Chapter 5 by removing the method setSpecies and adding the following methods:

-Five constructors: one for each instance variable, one with three parameters for the three instance variables, and a default constructor. Be sure that each constructor sets all of the instance variables.

-Four methods named set that can reset values: one is the same as the method setSpecies in Listing 5.19, and the other three each reset one of the instance variables.

Then write a test program to test all the methods you have added. Finally repeat Programming Project 1 in Chapter 5, but be sure to use some constructor other than the default constructor when you define new objects of the class Species.

Explanation / Answer

Construction primitives like: new Line( 200, 200, 300, 300, canvas); 13 import objectdraw.*; import java.awt.*; public class TouchyWindow extends WindowController f public void begin() f new Text( "Click in this window.", 20, 20, canvas); g public void onMousePress(Location point) f new Text( "I'm Touched.", 40, 50, canvas); g public void onMouseRelease(Location point) f canvas.clear();
