How to find minimum distance between two numbers in an array with Java

Answer 1

public class MyClass {
    public static int MinDistance(int[] arr, int number1, int number2) {
        int size = arr.length;
 
        int min_distance = Integer.MAX_VALUE;
 
        for (int i = 0; i < size; i++) {
            for (int j = i + 1; j < size; j++) {
                if (arr[i] == number1 && arr[j] == number2 || 
                    arr[i] == number2 && arr[j] == number1) {
                    min_distance = Math.min(min_distance, Math.abs(i - j));
                }
            }
        }
 
        return min_distance;
    }
    public static void main(String args[]) {
        int[] arr = {2, 3, 7, 3, 3, 4, 8, 8, 8, 11, 9, 1, 3};
 
        System.out.println(MinDistance(arr, 3, 8));
    }
}
