Write code for the following 2 methods:

void fillBoolean(boolean[] arr)
and
void printBoolean(boolean[] arr)

fillBoolean will fill the arr array passed in with alternating
true false values. For example:
arr[0] = true;
arr[1] = false;
arr[2] = true;
... etc.

The printBoolean routine will print out the contents of
the array arr passed in. Create a main routine to
test out your fillBoolean and printBoolean methods.

Write code for the following 2 methods:

int[] createIntegers(int size_of_array)
and
void printIntegers(int[] arr)

createIntegers will create an array the size specified in "size_of_array".
createIntegers will also fill the created array with values
that increase by 100.
For example:
arr[0] = 0;
arr[1] = 100;
arr[2] = 200;
... etc.

The printInteger routine will print out the contents of
the array arr passed in. Create a main routine to
test out your createInteger and printInteger methods.
