java - How to toString() a List like this one : List<Option>? -
suppose have list of object called option :
list<option> opts = arraylist<option>(); i have override tostring() object option.
when opts.tostring() means tostring list , unnecessary commas ,,,,,.
i change that. please, there way better for-looping inside list tostring each element ? hope clear.
i guess not idea override tostring of arraylist, can create own print function in utility class of application:
public static string mytostring(list<?> list) { stringbuilder stringlist = new stringbuilder(); string delimiter = " "; (int c = 0; c < list.size(); c++) { stringlist.append(delimiter); stringlist.append(list.get(c)); } return stringlist.tostring(); }
