刺激吃鸡

Effective Java 第三版第二章第一节有详细介绍

我简单摘录一下：

### 优点

One advantage of static factory methods is that, unlike constructors, they have names.

A second advantage of static factory methods is that, unlike constructors, they are not required to create a new object each time they ’ re invoked.

A third advantage of static factory methods is that, unlike constructors, they can return an object of any subtype of their return type.

A fourth advantage of static factories is that the class of the returned object can vary from call to call as a function of the input parameters.

A fifth advantage of static factories is that the class of the returned object need not exist when the class containing the method is written.

### 缺点

The main limitation of providing only static factory methods is that classes without public or protected constructors cannot be subclassed.

A second shortcoming of static factory methods is that they are hard for programmers to find.

### 一些常见的静态构造方法

**from**: A type-conversion method that takes a single parameter and returns a corresponding instance of this type, for example:

```java
Date d = Date.from(instant);
```

**of**: An aggregation method that takes multiple parameters and returns an instance of this type that incorporates them, for example:

```java
Set<Rank> faceCards = EnumSet.of(JACK, QUEEN, KING);
```

**valueOf**: A more verbose alternative to from and of, for example:

```java
BigInteger prime = BigInteger.valueOf(Integer.MAX_VALUE);
```

**instance** or **getInstance**: Returns an instance that is described by its parameters (if any) but cannot be said to have the same value, for example:

StackWalker luke = StackWalker.getInstance(options);

**create** or **newInstance**: Like instance or getInstance, except that the method guarantees that each call returns a new instance, for example:

```java
Object newArray = Array.newInstance(classObject, arrayLen);
```

根据我的实践，在 windows 上用 docker 最佳的方案是虚拟机，里面装个 Linux，然后再用 docker。虚拟化可以用 VirtualBox

和下家公司谈，推迟入职时间，如果真的想招你，不差这点时间

另，普通岗位离职不需要别人“同意”，你只需要发出“通知”，然后在一个月内做好交接就可以了

不过如果都是程序员，用 Issue 是 OK 的

“有了 gitlab，不想再搞一个 bug 管理工具了”，这是什么思维？
