Tampa Program that Receives a List of Integers Through Its Command Line Project

Tampa Program that Receives a List of Integers Through Its Command Line Project

Question Description

Programming Project 5
Write a program that receives a list of integers through its command line and finds the maximum integer number.
Requirements:
The program needs to check each input. After validation, it reports incorrect inputs to the user. Each correct input must be converted into an Integer object using Integer wrapper class. After that, the Integer object must be stored in an arraylist.
Now, you have an arraylist which includes all valid user inputs. Using a for loop, go through all the elements of the arraylist to find the maximum number and report the maximum number to the user as program output.
Steps:
1. Loop through all the elements of args string array. 2. For each string, call the convertToInteger method to convert the string into a Integer object. The converter method throws a NumberFormatException exception if it fails in the conversion process. 3. The call from the main method to convertToInteger method must be placed within a try-catch block. To report the appropriate error message to the user, the error output message must be placed in catch section.
try{ integerValuesList.add(convertToInteger(…));
} catch (NumberFormatException e){ …
}
4. Loop through all the elements of the arraylist. 5. Find the maximum element. 6. Report the maximum number to the user.
Sample program run and output:
>java CommandLineConverter 3 10 test 30 5 Error: For input string: “test” Maximum number is 30
Submit your CommandLineConverter.java source file to the Blackboard.
