Goal: Learn how to handle file operations and array manipulations through methods.

Assignment: Complete the code given below to define a public static void method processFile that, for each line of an input txt file, reads a number n and writes to a second file the following line:

The square of $[$n$]$ is $[$n$**2].$

where $[$n$]$ and $[$n$**2]$ should be replaced by the read number and its square, respectively.

Specifically:

the method takes as its first input argument a String representing the name of the file where the numbers are stored;

the method takes as its second input argument a String representing the name of the new file that should be written;

assume all the necessary libraries have been imported.

Example: If numbers.txt initially contains:

$1$

$2$

$3$

After running processFile$("$numbers$.$txt$",$ "squared$\_$numbers.txt$"),$ the content of squared$\_$numbers.txt should be:

The square of $1$ is $1.$

The square of $2$ is $4.$

The square of $3$ is $9.$
