Short Answer (Pgs. 360, 541, 810) 1. Assuming that array1 and array2 are both array reference variables, why is it not possible to assign the contents of the array referenced by array2 to the array referenced by array1 with the following statement? array1 = array2; By using the assignment operator on the variables, you are simply copying the reference from one array to another. In effect, both array1 and array2 will point to the same location in memory, and anything that’s changed in one will be changed in the other. Arrays must be copied element-by-element using a loop to get a true duplication of an array.
