java - Name object by string variable -

the idea current year system running in, name study record after year , therefore refer current year.

basically string variable , use name of object. have seen similar not accurate want , lack explanation looking for.

date = new date();c // current date     string currentyearrecord = integer.tostring(now.getyear()); // set string variable use name object studyrecord currentyearrecord = new studyrecord(); // name object string year got previous line. 

unfortunately, manipulating variable names @ runtime not possible in java language. kind of feature possible in dynamic languages, python or javascript.

in plain java, can use map achieve need:

map<string, studyrecord> records; // init map , fill when relevant  studyrecord currentyearrecord = records.get(integer.tostring(now.getyear())) 

if need feature, have @ groovy, dynamic language running on jvm close syntax java.
