What would be what you want when array size is 6?
Depends what behaviour you desire. a[3] will be the 4th element in the array leaving 2 on the right hand side and 3 on the left hand side. There's no way you can split it evenly.
maybe
return new int[]{(a[(a.length-1)/2]+a
return new int[]{(a[(a.length-1)/2]+a
maybe
return new int[]{(a[(a.length-1)/2]+a[a.length/ 2])/2,(b[( b.length-1 )/2]+b[b.l ength/2])/ 2};
Still same issue. I think @gudii9 is asking how to handle arrays that are not equally splittable in half.
In short, you can't.

Given 2 int arrays, a and b, each length 3, return a new array length 2 containing their middle elements.
say if above challenge modified to below
Given 2 int arrays, a and b, each length 3 or 9 or any odd number(i guess other than 1!!), return a new array length 2 containing their middle elements.
Then how to extend my solution to accomodate it. please advise
return new int[]{a[a.length/2],b[b.le
works for any odd number
return new int[]{(a[(a.length-1)/2]+a
also works for any odd number and extends the solution in a symmetric way for even numbers
works for any odd number
return new int[]{(a[(a.length-1)/2]+a
also works for any odd number and extends the solution in a symmetric way for even numbers
The solution I posted works for any length
Guddi9 can u tell me if the solution I provided works or not? If not tell me the expected outcome versus actual outcome

i wonder how works for any size other than 3. Let us say array size is 6 then 6/2=3 so
middleWay[0] = a[3];
middleWay[1] = b[3];
which may not be what we want in this challenge? please advise
