Main is written for you. You must fill in the code for the following methods:

$//$ returns a ref to an array twice as long as the one passed in$.$ With all data copied into it

static String$[]$ upSizeArray$($ String$[]$ fullArr $)$

$\{$

return null; $//$ just to make it compile

$\}$

$//$ creates a smaller array just big enough to hold the data and returns that "shrink wrapped" array of the data

static String$[]$ trimArray$($ String$[]$ arr, int count $)$

$\{$

return null; $//$ just to make it compile

$\}$

Here is your starter file: Project$2.$java

Here is your input file: $170$kWords.txt

Here is a snapshot of the expected output. As usual, DO NOT MODIFY MAIN. Just fill in the methods.

Do not use System or Arrays built in function calls to write these methods. You must write the loops yourself
