You can either use classical for loop with the index or advanced foreach loop introduced in Java 5 to iterate over an array in Java. If you need the index to select some element or do something else, use for loop otherwiseadvanced foreach loopis better. It's less error-prone as you d...

// System.out.println(Arrays.toString(downArr)); for(int i = 0; i<arr.length; i++){ res[i] = upArr[i]*downArr[i]; } return res; } }
although passing an array as arguments to a method with variable arguments in Java is similar to using varargs and the '...' argument. This separation between the type of the reference and the type of each element of the array allows for the...
The absence ofimport java.lang.reflect.Arraymakes it impossible for it to recognizeArray. However, Oracle suggests avoiding the use of reflection altogether. The practice of reflection is often employed in programs that need to analyze or alter the runtime conduct of Java virtual machine application...
