JList中的选定值

Question

Could someone tell me how can I get amount of selected value in JList? I use MULTIPLE_INTERVAL_SELECTION in my code to select more than one value.

Answer 1

1. Read the JList API
2. There are two methods that start with getSelected...() . Pick one of the methods to use.
3. Create a loop that iterates through all the values returned from the above method
4. Convert each value to a number and add the number
5. display the total value.
