*7.13 (Random number chooser) Write a method that returns a random number between 1 and 54, excluding the numbers passed in the argument. The method header is specified as follows: public static int getRandom(int... numbers)
import java.util.Scanner; public class ProgrammingEx7_13 { public static void main(String[] args) { Scanner input = new Scanner(System.in); int[] numbers = new int[10]; System.out.print("Enter 10 integers to exclude from:"); for (int i = 0; i < numbers.length; i++) { numbers[i] = input.nextInt(); } System.out.println("List of 100 random numbers:"); for (int i = 0; i < 100; i++) { System.out.println(getRandom(numbers)); } } public static int getRandom(int... numbers) { int getRandom = 0; boolean flag = true; // Loop until random number in not an argument list while (flag) { getRandom = intRandom(1, 54); // Assuming that the random number is not in arg list flag = false; // Test the assumption for (int i : numbers) { // If assumption is false, reset flag to true to generate new // random number if (getRandom == i) { flag = true; break; } } } return getRandom; } // Generate random integer between upper and lower bound public static int intRandom(int lowerBound, int upperBound) { return (int) (lowerBound + Math.random() * (upperBound - lowerBound + 1)); } }
