i implemented class:
public class tableinfogroup { vector<tableinfo> tableinfovector; public tableinfogroup(vector<string> tablenamevector, vector<string> tabletagidvector) { if (tablenamevector.size() != tabletagidvector.size()) return;//i think it's not proper tableinfovector = new vector<tableinfo>(); for(int = 0; < tablenamevector.size(); i++) tableinfovector.add(new tableinfo(tablenamevector.get(i), tabletagidvector.get(i))); } }
how elegant? throws exception? thanks.
personally, make method throw illegalargumentexception
:
thrown indicate method has been passed illegal or inappropriate argument.
for example:
if (tablenamevector.size() != tabletagidvector.size()) throw new illegalargumentexception("tablenamevector , tabletagidvector " + "must have same size");
even though illegalagumentexception
unchecked exception, still add method's throws
clause documentation.
making constructor throw exception prevent object being constructed, argue correct course of action in case.
