Batch File - Delete a File only if another file exists -

-

i wish create batch file can following:

if "file 1abc (x).bin" exists delete "file 1abc (y).bin", if not, keep "file 1abc (y).bin" , move on.

basically there multiple versions of file 1 kind (marked single variable in filename stays same) superior other. if superior version not exist, wish inferior version remain.

is possible?

you use if statement (http://www.computerhope.com/if.htm):

if exist file1.ext del file2.ext

update - address specific problem mentioned in question:

set filenames="file 1abc (*).bin" set lastversion="" :: find last version %%f in (%filenames%) (     if "%%f" gtr %lastversion% set lastversion="%%f" ) :: delete old versions %%f in (%filenames%) (     if "%%f" lss %lastversion% del "%%f" )

there 1 catch: if version (x or y in example) number, should specified fixed number of digits (e.g. (009), (010), ...), because (9) considered greater (10).

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.
