Diff and intersection reporting between two text files

a 夏天 提交于 2019-12-04 11:32:21
Disclaimer: I am new to programming and scripting in general so please excuse the lack of technical terms So i have two text file data sets that contain names listed: First File | Second File bob | bob mark | mark larry | bruce tom | tom I would like to run a script (pref python) that outputs the intersection lines in one text file and the different lines in another text file, ex: matches.txt : bob mark tom differences.txt : bruce How would I accomplish this with Python? Or with a Unix command line, if it's easy enough? words1 = set(open("some1.txt").read().split()) words2 = set(open("some2

difference between equals() and hashCode()

大兔子大兔子 提交于 2019-12-04 09:19:59
问题 I want a brief definition about the equals() , "==" and hashCode(). If i run following code means the output will be "true false 2420395 2420395". But i had understand that equals() method compares the string and "==" compares the reference. But in output the hashCcode() method prints the reference number for both strings as same then why the "==" returns "false". String str = "Name"; String str1 = new String("Name"); if(str.equals(str1)) System.out.println("true"); else System.out.println(

PHP compare two dimension array

I would like to know how to compare two two-dimension arrays value. First array Array 1 ( [0] => Array ( [0] => a ) [1] => Array ( [0] => b ) [2] => Array ( [0] => c ) } Second one Array 2 ( [0] => Array ( [0] => a ) [1] => Array ( [0] => d ) [2] => Array ( [0] => e ) } I need to make my loop to compare the arrays and check the matched value. In my case, array1[0][0]=a matches array2[0][0]=a. If it matches, php will output some html. My foreach loop foreach ($array1 as $arrays){ foreach($arrays as $array){ //need to compare array2 here not sure how to do it. } } Amber foreach($array1 as $k1 =>

如何给文件对比工具自定义快捷键

Beyond Compare是目前应用非常广泛的一款文件和文件夹比较工具,但是也有少部分用户觉得软件用起来有些不顺手,执行一次比较会话操作要花费好长时间,其实主要是因为没有学会使用快捷键。现在最新 Beyond Compare 4中文版已经强势来袭,有一些软件自设的快捷键是非常有用的,下面主要介绍一下自定义Beyond Compare快捷键的方法。 具体操作步骤如下所示 由于Beyond Compare软件可执行比较会话类型丰富,本文将以文本比较会话为例讲解自定义快捷键的方法。 步骤一:打开Beyond Compare软件,在主页面左侧的新建会话目录中双击“文本比较“会话,打开会话操作界面。此外您也可以直接选中需要比较的两份文本文件,右键文件并在展开的菜单中选择”比较“选项。 步骤二:单击比较会话界面“工具“按钮,在展开的菜单中选择”选项“操作,打开选项窗口界面,在界面左侧目录单击选择”工具栏等“选项。 Beyond Compare文本比较工具菜单图例 步骤三:在页面左侧“工具栏,快捷键,菜单”中设有命令栏目,假设现将“保存快照”选项的快捷键设为“Backspace”。 您需要先在命令栏目中选中“保存快照”选项,接着在栏目底部快捷方式文本框中输入相应数值。先单击“应用”按钮,再单击“确定”按钮,关闭窗口即可完成设置。 Beyond Compare设置快捷键操作界面图例

Comparing generic types Java

I have a problem with comparing generic types. In C# i I've always done something like that: class Element<T, V> where T : IComparable<T> . My question is how can it be written in java? I suspect you want something like: class Element<T extends Comparable<T>> ... using the Comparable interface and a bounded type parameter . 来源: https://stackoverflow.com/questions/15771215/comparing-generic-types-java

Beyond Compare有哪三种筛选器

我与影子孤独终老i 提交于 2019-12-04 07:42:18
作为文件对比工具 Beyond Compare 软件的功能是非常的强大的,在32位Windows系统中Beyond Compare比较的两边文件容量为250万文件,在64位Windows系统中其最大容量都是500万文件。但是我们所要对比的文件不是全部都需要比较的,这个时候有个筛选的工具就好了,下面就来给大家分享一下Beyond Compare如何设置才能过滤无关文件呢? 有三个总体类型的筛选器,可以帮助您控制文件夹比较范围 1、文件夹显示筛选器:控制显示文件夹。 2、显示筛选器:基于比较状态显示或隐藏行的比较。 3、文件筛选器:基于它们的名称或属性包含或排除文件。 例如,您可以通过“视图”选项卡,设置显示过滤器查看文件,可以只显示文件夹比较的左侧较新的文件。或者你也可以设置文件过滤器,如果你不希望看到或比较* .bak文件,可以借此排除它们。 默认情况下,在对选定文件夹的内容进行操作,如复制、移动、删除等将尊重目前的过滤器。如果所选内容包含一个文件夹,该文件夹的内容过滤会被跳过。 若要更改此默认行为,单击“工具”按钮,打开”选项“窗口界面,并切换到文件操作页面上,在过滤的项目中,勾选“按默认包含隐藏的项目”复选框。在任一情况下,操作对话框允许您在比较基础上覆盖默认行为。 Beyond Compare文件夹比较工具选项卡选项窗口界面图例 单击“视图”按钮,在展开的菜单选择“抑制过滤

Check if enum exists in Java

只愿长相守 提交于 2019-12-04 07:29:26
问题 Is there anyway to check if an enum exists by comparing it to a given string? I can't seem to find any such function. I could just try to use the valueOf method and catch an exception but I'v been taught that catching runtime exceptions is not good practice. Anybody have any ideas? 回答1: I don't think there's a built-in way to do it without catching exceptions. You could instead use something like this: public static MyEnum asMyEnum(String str) { for (MyEnum me : MyEnum.values()) { if (me.name

Comparing the contents of two files in Sublime Text

空扰寡人 提交于 2019-12-04 07:18:38
问题 I have two cloned repositories of two very similar open-source projects, which I have been working on in different instances in Sublime Text 2 to arrive at my desired result. Code from both of these projects was used. I have been using Git as version control for my project, but have not included the original projects. Thus, I would like to be able to quickly compare the contents of two files of the original project and compare the differences between them and my project. I was hoping that

library that identifies similar images

我是研究僧i 提交于 2019-12-04 06:59:21
I want to determine how similar 2 images are. The images may have been scaled, cropped, etc, so a simple pixel comparison won't work. I have had a look around and there are a lot of academic papers on this topic but they don't release their code. So, do you know of a released library that can compare images (for Linux and Windows)? I came across this fantastic list of software for computer vision: http://www.cs.cmu.edu/~cil/v-source.html And decided to look at these 2 tools in more detail: http://libpuzzle.pureftpd.org/project/libpuzzle http://appsrv.cse.cuhk.edu.hk/~jkzhu/felib.html 来源: https
