Answer:
B
Explanation:
When you have a method that is copying values from one array into another, you first have to initialize a new array which you can copy the values into. This is done by using the provided value "count".
int [ ] nums = new int [count];
Second, you have a "for each" loop that iterates over each index in the first array, and assigns the value at that index to the same index location in the copy array. In a "for each" loop, the variable "val" represents the content of an index, not an iterated value itself. This is why we can just do this inside the loop:
nums[ j ] = val;
That said, you still need "j" to be there and increment because we still need a tracking value for the current index in the copy array.
int j = 0;
for (int val: array)
{
copyArray[j] = val;
j++;
}
Third, you return the copy version of the array.
return nums;
