设计模式 02 创建类模式之简单工厂模式

interface Human {
public void Talk();
public void Walk();
}

class Boy implements Human{
@Override
public void Talk() {
System.out.println("Boy is talking...");
}

@Override
public void Walk() {
System.out.println("Boy is walking...");
}
}

class Girl implements Human{

@Override
public void Talk() {
System.out.println("Girl is talking...");
}

@Override
public void Walk() {
System.out.println("Girl is walking...");
}
}

public class HumanFactory {
public static Human createHuman(String m){
Human p = null;
if(m.equals("boy")){
p = new Boy();
}else if(m.equals("girl")){
p = new Girl();
}

return p;
