Hands-On Design Patterns with Java

Programming the design pattern

Our implementation starts with a Mower interface. It has a single mow() method:

public interface Mower {    void mow();}

The following segment of code is the MowerFactor abstract class. There, we will have the ConcreteMowerFactory subclass:

abstract class MowerFactory {    public abstract Mower getMowerType(String mowerType);}

The Riding class represents the class object for this type of mower. It implements the Mower interface. It overrides the mow() method and outputs text that's specific to this type of Mower:

public class Riding implements Mower {    @Override    public void mow() {        System.out.println("Riding mowers provide safety and comfort.");    }}

The Push class represents the class object for the push mower type. ...
