css - How can I reduce this repetition -

-

i have css can see repeating same thing different categories...how can reduce code?

.dropdown .cars-category{    float: left;    margin-left: 1%;  }   .dropdown .trucks-category{     float: right;     margin-right: 1%; }   .dropdown .trucks-category > li > {     display: block;     clear: both;     line-height: 20px;     color: #546aa4; }  .dropdown .trucks-category > li.last > {     border-bottom-width: 0; }  .dropdown .trucks-category > li > a:hover, .dropdown .trucks-category > li > a:focus,  .dropdown .trucks-category > .active > a, .dropdown .trucks-category > .active > a:hover, .dropdown .trucks-category > .active > a:focus {     color: #546aa4;     text-decoration: none;     background-color: #e7eded;     outline: 0; }   .dropdown .cars-category > li > {     display: block;     clear: both;     line-height: 20px;     color: #546aa4; }  .dropdown .cars-category > li.last > {     border-bottom-width: 0; }  .dropdown .cars-category > li > a:hover, .dropdown .cars-category > li > a:focus,  .dropdown .cars-category > .active > a, .dropdown .cars-category > .active > a:hover, .dropdown .cars-category > .active > a:focus {     color: #546aa4;     text-decoration: none;     background-color: #e7eded;     outline: 0; }

opt 1 - change html , reduce

using 2 classes instead of hyphenated class going reduce most. instead of class="trucks-category" in html, use class="trucks category" andclass="cars category". also, of last block unnecessary (assuming .active on li element). reduces 7 selectors:

.dropdown .cars.category { /*could eliminate .category if no other .cars under */     float: left;            /*the .dropdown menu, see .trucks example */    margin-left: 1%; }   .dropdown .trucks { /*removed category if not needed differentiate */     float: right;     margin-right: 1%; }   .dropdown .category > li > {     display: block;     clear: both;     line-height: 20px;     color: #546aa4; }  .dropdown .category > li.last > {     border-bottom-width: 0; }  .dropdown .category > .active > a, .dropdown .category > li > a:hover,  .dropdown .category > li > a:focus /* .dropdown .category > .active > a:hover, unneeded */ /* .dropdown .category > .active > a:focus unneeded */ {     color: #546aa4;     text-decoration: none;     background-color: #e7eded;     outline: 0; }

opt 2 - target same value on class name

like option 1, keeping hyphenated classes. useful if not have other -category classes different css , under .dropdown. if not, works:

.dropdown .cars-category {     float: left;                margin-left: 1%; }   .dropdown .trucks-category {     float: right;     margin-right: 1%; }   .dropdown [class*="-category"] > li > {     display: block;     clear: both;     line-height: 20px;     color: #546aa4; }  .dropdown [class*="-category"] > li.last > {     border-bottom-width: 0; }  .dropdown [class*="-category"] > .active > a, .dropdown [class*="-category"] > li > a:hover,  .dropdown [class*="-category"] > li > a:focus {     color: #546aa4;     text-decoration: none;     background-color: #e7eded;     outline: 0; }

i put option 1 1 because feel having separate class names more intuitive , more flexible.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
