在Java中, 使用包来管理类. 就像在资源管理器中使用文件夹管理文件一样 在同一个包中, 类名不能重名, 在不同包中类名可以相同 常见的包 java.lang Java语言的基础包, 系统会自动导入 ​ java.util 工具类 ​ java.io 输入输出相关的类 ​ java.text 文本处理相关的类 ​ java.net 网络相关的类 ​ java.math 数学相关的类 1. 包的定义 使用package关键字定义包, package定义包的语句必须作为源文件的第一条语句 包名的命名规则: 公司域名的倒序.项目名.模块名.子模块名 package com.bjpowernode.chapter01.packages.p1; 包名一般情况下所有字母都小写 编译 javac -d . Test01.java ​ javac的-d参数可以指定生成字节码文件的位置(目录) ​ 小点.代表当前目录 ​ 编译后,系统会在当前目录生成与包名对应的文件夹,把字节码文件存储到该文件夹中 运行 ​ >java com.bjpowernode.chapter01.packages.p1.Test01 ​ java命令后面跟完整类名 包名.类名就是完整类名,即 ​ com.bjpowernode.chapter01.packages.p1.Test01是一个完整类名 ​

How to get virtualenv to use dist-packages on Ubuntu?

由 丶灬走出姿态 提交于 2020-01-09 13:56:29
问题 I know that virtualenv, if not passed the --no-site-packages argument when creating a new virtual environment, will link the packages in /usr/local/lib/python2.7/site-packages (for Python 2.7) with a newly-created virtual environment. On Ubuntu 12.04 LTS, I have three locations where Python 2.7 packages can be installed (using the default, Ubuntu-supplied Python 2.7 installation): /usr/lib/python2.7/dist-packages : this has my global installation of ipython, scipy, numpy, matplotlib –

How to get the list of options that Python was compiled with?

由 心已入冬 提交于 2020-01-09 12:13:31
问题 You can compile Python in various ways. I'd like to find out with which options my Python was compiled. Concrete use-case: was my Python compiled with readline? I know I can see this by doing "import readline", but I'd like to see a list of compilation setting for my Python binary. Edit: I mean the Python executable and not source code written by myself. 回答1: There is a module to see the system config import sysconfig print(sysconfig.get_config_vars()) It offers an interface to get individual

Global variable in a package - which approach is more recommended?

由 牧云@^-^@ 提交于 2020-01-09 11:24:17
问题 I do understand that generally global variables are evil and I should avoid them, but if my package does need to have a global variable, which of these two approaches are better? And are there any other recommended approaches? Using an environment visible to the package pkgEnv <- new.env() pkgEnv$sessionId <- "xyz123" Using options options("pkgEnv.sessionId" = "xyz123") I know there are some other threads that ask about how to achieve global variables, but I haven't seen a discussion on which

Is self-reference possible in MATLAB?

由 ♀尐吖头ヾ 提交于 2020-01-09 07:12:45
问题 As noted here, functions in packages, as well as static methods in classes, still need to use a packagename.functionname syntax or import packagename.* for each function (since the imports are part of the function workspace and not global). This means that changing the package/class name later on can become a tedious nuisance. Is there any way to do something like import this.* , i.e. a package/class name agnostic method to access all functions/static methods in the same package/class? 回答1:

一、下载azkaban 官网：https://azkaban.github.io/downloads.html GitHub下载地址：https://github.com/azkaban/azkaban 下载： [root@salt ~]# git clone https://github.com/azkaban/azkaban.git 二、安装 1、构建 我这里没有用git下载，是直接下载的压缩包，不过都问题不大； 1、编译成tar包（如果不是第一次构建需要先clean，执行：./gradlew clean） [root@salt azkaban]# cd /opt/azkaban/azkaban-3.81.0/ [root@salt azkaban]# vim azkaban-common/src/main/java/azkaban/jobExecutor/ProcessJob.java 将final boolean isExecuteAsUser = this.sysProps.getBoolean(EXECUTE_AS_USER, true); 里面的true修改为false [root@salt azkaban-3.81.0]# ./gradlew distTar #最后会显示：BUILD SUCCESSFUL 2、把相应的tar包复制出来 [root@salt
