    In Java:

    public static String twoArrays(int k, List<Integer> A, List<Integer> B) {

    // Ordering A in ascending order
   A.sort((a, b) -> Integer.compare(a, b));
   // Ordering B in descending order
   B.sort((a, b) -> Integer.compare(b, a));

   for(int i=0;i<A.size();i++){
    if(A.get(i) + B.get(i) < k){
    return "NO";
    }

   }

    return "YES";

    }

    Kotlin Solution

    fun twoArrays(k: Int, A: Array<Int>, B: Array<Int>): String {
    A.sort()
    B.sortDescending()
    for(i in A.indices){
        if(A[i]+ B[i] < k){
            return "NO"
        }
    }
    return "YES"
}

    Python solution:

    def twoArrays(k, A, B):
    # Write your code here
    for a in A:
        low = k-a
        bs = [b for b in B if b >=low]
        if bs: #if bs not empty
            B.remove(min(bs))
        else: # if bs empty
            return 'NO'
    return 'YES'

    simple very pythonic solution: 

    def twoArrays(k, A, B):
    # Write your code here
    A.sort()
    B.sort(reverse=True)
    comprobations = [x + y >= k for x,y in zip(A, B)]
    return "YES" if all(comprobations) else "NO"
