Question

so we will create a frame which will have label boxes for first name, last name, and date of birth. Input will be taken from the user and when the user fills the date box it should show calendar from where a user can pick a date. Give the color palette to the user which could have up to 10 colors and the user can choose a background from that color palate.

Once the all is done we have two buttons one for Done and another Cancel. If the user press Done all the information means first name, last name, and date of birth will be stored to any file in your pc.

All should be done in java using swing
