Expert Solution
Step 1

Program is written. If we not initialize the count variable, we will get compile time error. So count variable must be initialized.

Algorithm:

Step 1: Write main() method

Step 2: Declare and define the count variable with 0 (int count = 0)

Step 3: Load the inputFile.txt lines using File file = new File("inputFile.txt");

Step 4: Declare and define Scanner input = new Scanner(file);

Step 5: Using while loop count the number of lines in the given lines and store the count in count variable

Step 6:  Close the input
