database - How to create a table in Java? -

-

i want create sort of table in java. tried using hashmap:

public map<string, double> namesandprices = new hashmap<string, double>();

this doesn't work when want add string so:

public map<string, double, string> namesandprices = new hashmap<string, double, string>();

what class can use create sort of table in java can values , not.

use objects, rather trying put unstructured data collections.

your map should map<string, product>, product objects containing name, price, , other properties of products.

btw, told in your previous question, , accepted answer.
