java - Compare elements in an array for duplicates

Question

I am trying to generate a 5 digit int array in Java and am having trouble on where to start. None of the numbers in the array can be duplicates. I can generate random numbers for it fine but just cant figure out how to compare the numbers to each other and replace any duplicates.

Answer 1

You can use a java.util.Set instead of an array as it is guaranteed to have only unique elements.
