SIMPLE JAVA8 CODING SOLUTION

public static void miniMaxSum(List<Integer> arr) {
// Write your code here
    long sum = 0; // Using long to avoid overflow issues
    int min = Integer.MAX_VALUE;
    int max = Integer.MIN_VALUE;

    // Calculate the total sum and find min and max values
    for (int num : arr) {
        sum += num;
        min = Math.min(min, num);
        max = Math.max(max, num);
    }

    // Calculate the minimum and maximum sums
    long minSum = sum - max; // Sum of all except max
    long maxSum = sum - min; // Sum of all except min

    System.out.println(minSum + " " + maxSum);
