Builder(创建者模式)

Builder -- 抽象创建者

package com.dzeay.pattern.builder;public abstract class Builder {    public abstract void a();    public abstract void b();    public abstract void c();    public abstract void d();    public abstract void e();}

Builder -- 创建者实现

package com.dzeay.pattern.builder;public class BuilderImpl extends Builder {    @Override    public void a() {        System.out.println("BuilderImpl.a");    }    @Override    public void b() {        System.out.println("BuilderImpl.b");    }    @Override    public void c() {        System.out.println("BuilderImpl.c");    }    @Override    public void d() {        System.out.println("BuilderImpl.d");    }    @Override    public void e() {        System.out.println("BuilderImpl.e");    }}

Builder --

package com.dzeay.pattern.builder;public class Driector {    private Builder builder;    public void builder() {        builder = new BuilderImpl();        builder.a();        builder.b();        builder.c();        builder.d();        builder.e();    }}
