I need help with the following program using Java.

The program is supposed to sort a list of science fair judges into a science fair catogory they can judge. The list of judges has the judge's name and subject it will look like this.

Ben Miller: Biology, Chemistry

Joe Hansen: Chemistry, Earth Science

Jill Clemson: Behavioral/Social Science, Life Science, Environmental Science

Cathy Lively: Life Science

Francisco Aranda: Chemistry, Mathematics/Physics

Betty Baines: Environmental Science

Jim Green: Life Science

Bill Jones: Chemistry, Behavioral/Social Science, Earth/Space Science, Mathematics//Physics, Environmental Science

Susan Garcia: Life Science

Jamie Aguirre: Mathematics/Physics

Carla Phillips: Earth/Space Science

Tony Brown: Life Science

Joseph Martin: Life Science, Environmental Science

Chris Suarez: Environmental Science, Behavioral/Social Science

Sara Rodriguez: Chemistry

Karen Simi: Mathematics/Physics, Environmental Science

Maria Gonzales: Life Science, Chemistry

Leticia Jones: Chemistry

Jamie Garcia: Earth/Space Science, Mathematics/Physics, Chemistry

The list of projectws will have a project number followed the subject it falls into, that looks like this.

403 Chemistry

412 Chemistry

400 Behavioral/Social Science

407 Chemistry

410 Chemistry

417 Life Science

415 Environmental Science

419 Life Science

411 Chemistry

420 Mathematics/Physics

421 Mathematics/Physics

408 Chemistry

409 Chemistry

406 Chemistry

401 Behavioral/Social Science

416 Environmental Science

413 Earth/Space Science

405 Chemistry

414 Environmental Science

402 Behavioral/Social Science

418 Life Science

404 Chemistry

The progrram should get the two input files, one for the subjects th eother the judges and read them and then produce a group of the judges that will judge each project. The maximum number of judges in a group is 3 and the most projects they can judge is 6 out put can look something like this

Chemistry_1 Bill Jones, Joe Hansen, Sara Rodriguez

Projects: 403, 404, 405, 406, 407, 408

Chemistry_2 Jamie Garcia, Leticia Jones, Maria Gonzales

Projects: 409, 410, 411, 412

As it stands the sorting is not working properly.
