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
