用java回答的问题

有两个整数数组A{1,5,9,12,46,47,63,69,70,81}和B{2,4,6,10,29,78,91}，其元素均按从小到大的升序排列，编程将它们合并成一个数组C，要求C的元素也是从小到大的升序排列。

        int[] A = {1,5,9,12,46,47,63,69,70,81};
        int[] B = {2,4,6,10,29,78,91};
        int i = 0, j = 0;
        int[] C = new int[A.length+B.length];
        while (true){
            if (i == A.length){
                if (j == B.length){
                    break;
                }else {
                    for (;j < B.length;j++){
                        C[i+j] = B[j];
                    }
                    break;
                }
            }
            if (j == B.length){
                if (i == A.length){
                    break;
                }else {
                    for (;i < A.length; i++){
                        C[i+j] = A[i];
                    }
                    break;
                }
            }
            if (A[i] < B[j]){
                C[i+j] = A[i];
                i++;
            }else {
                C[i+j] = B[j];
                j++;
            }
        }

        System.out.println(Arrays.toString(C));

public static void main(String[] args) {
    Integer A [] ={1,5,9,12,46,47,63,69,70,81};
    Integer B [] ={2,4,6,10,29,78,91};
    List<Integer>  arrayA = new ArrayList(Arrays.asList(A));
    List<Integer>  arrayB = new ArrayList(Arrays.asList(B));
    arrayA.addAll(arrayB);
    Collections.sort(arrayA);
    List<Integer> arrayC;
    arrayC=arrayA;
    int size =arrayC.size();
    for (int i = 0;i < size;i++) {
        System.out.println(arrayC.get(i));
    }

}
