Question

Only number 5

4. Say we wanted to get an iterator for an ArrayList and use it to loop over all items and print
them to the console. What would the code look like for this?
5. Write a method signature for a method called foo that takes an array as an argument. The
return type is void.
6. What is the difference between remove and clear in ArrayLists.

Expert Solution

Step 1

Method signature consists of the method name and a parameter list (number of parameters, type of the parameters and order of the parameters).

All the other elements of the method's declaration, such as modifiers, return type, parameter names, exception list, and body are not part of the signature

Its syntax is:

methodName(argumentsType)

Given

methodName is foo

arguments is an array

I am assuming integer array
