設計模式
好了，開始這是我自己用形狀，大小來描述橋梁模式的方式：
可以分為四種：大圓，小圓，大矩形，小矩形
看代碼：
public interface Shape {
public abstract void DrawShape();
}
public class Circle implements Shape {
public Circle() {
// TODO Auto-generated constructor stub
}
public void DrawShape() {
// TODO Auto-generated method stub
System.out.println("我是圓");
}
}
public class Triangle implements Shape {
public Triangle() {
// TODO Auto-generated constructor stub
}
public void DrawShape() {
// TODO Auto-generated method stub
System.out.println("我是矩形！");
}
}
public abstract class Type {
public abstract void draw(String str);
protected Shape GetShape(String type){
if(type.equals("circle")){
return new Circle();
}else if(type.equals("triangle")){
return new Triangle();
}else{
return Circle();
}
}
private Shape Circle() {
// TODO Auto-generated method stub
return new Circle();
}
}
public class Big extends Type {
private Shape shape;
public Big(String tr){
shape=GetShape(tr);
}
public void draw(String str) {
// TODO Auto-generated method stub
System.out.println(str);
System.out.println("大");
shape.DrawShape();
}
}
public class Small extends Type {
private Shape shape;
public Small(String str) {
shape=GetShape(str);
}
public void draw(String tr){
System.out.println(tr);
System.out.println("小");
shape.DrawShape();
}
}
可以測試一下啊：
public class Test {
public static void main(String[] args) {
System.out.println("=============小類型================");
//small類型時候
Type type=new Small("triangle");
type.draw("triangle");
Type type2=new Small("circle");
type2.draw("circle");
System.out.println("=============大類型================");
//Big類型時候
Type type3=new Big("circle");
type3.draw("circle");
Type type4=new Big("triangle");
type4.draw("triangle");
}
}
設計模式相當強悍啊！能幫助大家學習一點本人心得也算很愉快了！我會繼續吧所學貢獻出來的！
