# Chocolatey

[Chocolatey](https://chocolatey.org/) can be used to install most of the items below, and is well worth checking out.

Browse the [Chocoloatey Gallery](https://chocolatey.org/packages), or install [ChocolateyGUI](https://chocolatey.org/packages/ChocolateyGUI).

## Export / Import Chocolatey Packages

Use this PowerShell script to export your Chocolatey packages:

```powershell
# Put this in Export-Chocolatey.ps1 file and run it:
# Export-Chocolatey.ps1 > packages.config
Write-Output "<?xml version=`"1.0`" encoding=`"utf-8`"?>"
Write-Output "<packages>"
choco list -lo -r -y | % { "   <package id=`"$($_.SubString(0, $_.IndexOf("|")))`" version=`"$($_.SubString($_.IndexOf("|") + 1))`" />" }
Write-Output "</packages>"
```

You could then install the exported `packages.config` file using:

```bash
choco install packages.config -y
```

# Java

Install [Java 8 JRE](https://java.com/en/download/), [OracleJDK](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html) or [OpenJDK](http://openjdk.java.net/) as required.

If using [Chocolatey](https://chocolatey.org/) you can install the [Zulu OpenJDK](https://zulu.org/download/) with `choco install zulu8`.

markdown nullptr

notes.md

使用 `nullptr` 初始化对象能避免 0 指针的二义性的问题。
