java - HashMap help, Read from file print to console or JTextArea

Question

I'm having a problem using HashMap. I have test.txt with this data:

[Computers]
Keyboard=10
Mouse=5
[Cars]
Lamborghini=6
BMW=3

where the [Computers] & [Cars] are Category, Keyboard, Mouse, Lamborghini and BMW are descriptors, and 10, 5, 6, 3 are values for each descriptor.

How can I make a HashMap that can System.out.println("Category" + "descriptor" + value) on console or in JTextArea when clicking a button?

Answer 1

I think it can be done using two levels of hashmaps.

On first hashmap level, use category as your key and for its value, use another hashmap whose keys would be the descriptors.
