[LeetCode] Median of Two Sorted Arrays

There are two sorted arrays A and B of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)).

public class Solution {
	    public double findMedianSortedArrays(int A[], int B[]) {
	       int n = A.length;
	       int m = B.length;
	       int num = m+n;
	       int[] ab = new int[n+m];
	       for(int i=0;i<n;i++)
	       {
	    	   ab[i] = A[i];
	       }
	       for(int i=0;i<m;i++)
	       {
	    	   ab[i+n] = B[i];
	       }
	       
	       Arrays.sort(ab);
	       double medain;
	       if((num)%2!=0)
	       {
	    	   medain = (double)ab[(num+1)/2-1];
	       }
	       else
	       {
	    	   medain = (double)(ab[num/2-1]+ab[num/2])/2;
	       }
		return medain;
	       
	    }
	    
	}
