How can I add a method to the below Java code so the same random number not showing at print out. Example of how it not should be: [43, 41, 41, 20, 17, 16, 42] Thanks! import java.util.Arrays; import java.util.Random; public class Main { public static void main(String[] args) { int[] randomNumbers = new int[7]; Random random = new Random(); for (int i = 0; i < 7; i++) { randomNumbers[i] = random.nextInt(50) + 1; } System.out.println(Arrays.toString(randomNumbers)); } }
