设计原则：SOLID 可以说，五个设计原则各司其职。
单一职责原则(S)：用于类的设计
开闭原则(O)：总的指导思想
里氏替换原则(L)：用于指导类继承的设计
接口隔离原则(I)：用于指导接口的设计
依赖翻转原则(D)：用于指导如何抽象
类之间的关系：
继承=实现>组合>聚合>关联>依赖
public interface product { public void createProduct(); } public class conCreteProduct implements product { @Override public void createProduct() { // TODO Auto-generated method stub System.out.println("生产产品"); } } public class user { public static void main(String[] args) { // TODO Auto-generated method stub product prod1 = new conCreteProduct(); prod1.createProduct(); } }
public interface product { public void createProduct(); } public class conCreteProduct implements product { @Override public void createProduct() { // TODO Auto-generated method stub System.out.println("生产产品"); } } public class factory { public void createProduct() { product prod1 = new conCreteProduct(); prod1.createProduct(); } } public class user { public static void main(String[] args) { // TODO Auto-generated method stub factory fact1 = new factory(); fact1.createProduct(); } }
