Java Programming

hello!

i have a project that lets a user input the a date and then the event title and the description of the event for that date, the programs use is to to add, search and delete the date. i tried to include the use of GUI for this project but i failed so im using the console, but if i can slove this porblem that im with now, i might be able to include GUI.

well my problem is, i need to save the dates and events the user added. so that if the program is close the datas are still present and can be accessed anytime. how can i save it? im planning to save a linked list, is it possible? what would i use? would i use IO? and how? if i cant save a linked list what is the alternate method?

thank you so much for the time!
