Merge Sorted Array

Given two sorted integer arrays A and B, merge B into A as one sorted array.

Note:
You may assume that A has enough space (size that is greater or equal to m + n) to hold additional elements from B. The number of elements initialized in A and B are mand n respectively.

public class Solution {
    public void merge(int A[], int m, int B[], int n) {
        if(n==0) return;
        int i=m-1;
        int j=n-1;
        
        for(int k=m+n-1;k>=0;k--){
            if(i<0 && j>=0){
                A[k]=B[j--];
            }
            else if(i>=0 && j<0){
                A[k]=A[i--];
            }
            else if(A[i]>=B[j]){
                A[k]=A[i--];
            }
            else if(A[i]<B[j]){
                A[k]=B[j--];
            }
        }
    }
}
