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();
    }
}

Builder -- 测试类
