Assuming you have information stored in a text file (information.txt), each COLUMN is separated by a dot and the first ROW contains the row name for each column as follows:

ID.NAME.STATE.SEX.RELIGION.TRIBE
1.Tunde.Lagos.Male.Christian.Yoruba
2.ibrahim.Adamawa.Male.Muslim.Fulani
3.Chinyere.Imo.Female.Christian.Igbo
4.Dooshima.Benue.Female.Atheist.Tiv
5.Halima.Kano.Female.Agnostic.Hausa

• Copy the above data and save it in a text file as “information.txt”
• Using java write a program that takes information from information.txt and displays it on a JTABLE.
• Also create a JBUTTON (Refresh) that adds or removes rows from the table to reflect the current data in information.txt.
