java比较器 Copareble Comparetor Copareble Comparable接口的使用举例： 自然排序 1.像String、包装类等实现了Comparable接口，重写了compareTo(obj)方法，给出了比较两个对象大小的方式。 2.像String、包装类重写compareTo()方法以后，进行了从小到大的排列 3. 重写compareTo(obj)的规则： 如果当前对象this大于形参对象obj，则返回正整数， 如果当前对象this小于形参对象obj，则返回负整数， 如果当前对象this等于形参对象obj，则返回零。 4. 对于自定义类来说，如果需要排序，我们可以让自定义类实现Comparable接口，重写compareTo(obj)方法。 在compareTo(obj)方法中指明如何排序 //(1).String类重写了compareTo()方法,按照从小到大的顺序排序 @Test public void test1 ( ) { String [ ] arr = new String [ ] { "A" , "J" , "C" , "D" , "N" , "B" } ; Arrays . sort ( arr ) ; System . out . println ( Arrays . toString ( arr ) ) ; } //(2

1. 下载安装包： 2. 安装步骤 3. 运行并注册 之前Beyond compare 3 只有32位，在Ubunt 16.04上运行效率非常低，所以只有安装最新的Beyond compare 4，安装方法如下： 1. 下载安装包： bcompare-4.1.9.21719_amd64.deb 2. 安装步骤 sudo apt-get update sudo apt-get install gdebi sudo gdebi bcompare-4.1.9.21719_amd64.deb sudo cp /usr/lib/beyondcompare/BCompare /usr/lib/beyondcompare/BCompare.backup sudo sed -i "s/keexjEP3t4Mue23hrnuPtY4TdcsqNiJL-5174TsUdLmJSIXKfG2NGPwBL6vnRPddT7tH29qpkneX63DO9ECSPE9rzY1zhThHERg8lHM9IBFT+rVuiY823aQJuqzxCKIE1bcDqM4wgW01FH6oCBP1G4ub01xmb4BGSUG6ZrjxWHJyNLyIlGvOhoY2HAYzEtzYGwxFZn2JZ66o4RONkXjX0DF9EzsdUef3UAS+JQ+fCYReLawdjEe6t 大专栏 Ubunt 16.04

Is there a CompareTo method in C++ similar to Java where you can use > < = operations on a data type

由 爷，独闯天下 提交于 2020-02-05 06:57:06
问题 I know that in java there is a compareTo method that you can write in a class that will compare two variables and return a value -1, 1, or 0 signifing greater than, less than, and equal to operations. Is there a way to do this in C++? Background: Im creating a modified string class in which it takes a string and an arraylist. I want to be able to compare the string in a traditional fashion where if its lower in the alphabet it will be less than, than higher it would be greater than. Than i

PHP sort weekday and month-year array by custom order

由 可紊 提交于 2020-02-05 03:31:11
问题 I have an array of weekdays (see below) that I would like to sort as "Mon-Tue-Wed-Thu-Fri-Sat-Sun". "Sun"=>59 "Sat"=>41 "Fri"=>21 "Thu"=>11 "Wed"=>14 "Tue"=>19 "Mon"=>31 I tried the following code but it doesn't seem to work correctly, the result being the ordered array pasted above, i.e. not in the order I would like it to be. function orderbyweekday($a, $b) { if (strcmp($a, "Mon") == 0) $a = 0; else if (strcmp($a, "Tue") == 0) $a = 1; else if (strcmp($a, "Wed") == 0) $a = 2; else if (strcmp

一、str(stringcompare)函数 语法：strcomp(string1,string2 [,compare]) strcomp用于返回一个整型数值用以指示字符串比较的结果 表中的0表示记录一致，非0（包括空白）表示不一致 compare为字符串比较类型，如果compare为null，将发生错误；省略compare，执行文本比较 compare参数设置 值 说明 0 执行二进制比较 1 执行文本比较 strcomp函数的返回值 条件 返回值 string1<string2 -1 = 0 > 1 string1或者string2为空 空 二、cbool函数 如果没有数据缺失项 ，可以通过cbool函数返回结果，本质是转为布尔值 select 赵老师 , 王老师 , cbool ( 赵老师 = 王老师 ) as 是否相同 from [学生名单$] 结果表中-1表示记录一致(true),为0表示不一致(false) 1、cbool函数与strcomp函数的比较 比较内容 cbool函数 strcomp函数 参数数量 一个参数，必选 3个参数，其中参数compare可选 比较方式 二进制比较 二进制比较或文本比较 返回结果分类 两类：表达式结果为非零则返回true(-1),否则返回false(0) 三类：见strcomp说明 空值处理 返回错误值 返回空 三、iif函数
