Array Practice
(1)Write a method, getValue(int [ ] array) to have user enter the size
(length) of an integer array, then user is able to continuously enter
the integer values. (2)Write a method int getHighestValue() and int
getLowestValue() which returns the highest value and lowest in the
array respectively. (3) Write a method int[ ] geArray( int[ ] array1)
which receives an integer array array1 as parameter and returns an
duplicate integer array. (4) Write a main program to test it.
Well, you are going to need to start by writing a class to contain all
this. After that, I would do it in order (4), (2), (3), (1), testing (2)
and (3) with internally supplied data before trying to do the input
task. Start with a skeleton main method, then add a test, then add the
code to make that test work. Repeat as needed.
I find the description of (1) a bit confusing. It seems to be intended
to read in an array, but is defined as taking an array reference
parameter, rather than returning an array as result. Can you clarify? If
you don't know what it means, it might be something you should check
with your instructor.
In addition to the methods you have been told to write, it might be a
good idea to have a method that prints the contents of an array, so that
you can see what you are working with.
