Arrays.sort() is fine
follow this to handle the tle

public static void targetSum(int[] arr, int target){
        Arrays.sort(arr);
        int left = 0;
        int right = arr.length - 1;
        while (left < right) {
            int sum = arr[left] + arr[right];
            if (sum > target) {
                right--;
            } else if (sum < target) {
                left++;
            } else {
                System.out.println(arr[left] + " and " + arr[right]);
                left++;
                right--;
            }
        }
    }
