Write a Java Program.

you have three identical prizes to give away and a pool of 30 finalists. The finalists are assigned numbers from 1 to 30. Write a program to randomly select the numbers of three finalists to receive a prize. Make sure not to pick the same number twice. For example, picking finalists 3, 15, 29 would be valid but picking 3, 3, 31 would be invalid because finalist number 3 is listed twice and 31 is not a valid finalist number..
