TestScore.java A very simple driver class which you can use as a base. The problem description is to obtain a single valid test score from the user. Valid means that it is a floating point (or integer) in its format, and that this number is in the range [0, 100].
Your job is to add the necessary components to the program file so that the specification above is met. Suggested components:
a String variable
a boolean variable
a do loop
an if statement
a try and a catch block

Your finished program will produce output / runs similar to:
Please enter a test score [0, 100] : -1

Your job is to add the necessary components to the program file so that the specification above is met. Suggested components:

Remember all of the numeric parse methods throw a NumberFormatException when a given strings format does not match the types form.
Your finished program will produce output / runs similar to:
Please enter a test score [ 0,100] : -1
Please enter a test score [0,100]: 101
Please enter a test score [0,100]: hgwells
Please enter a numeric test score [0,100]: 78.5
The Valid score entered was 78.5 And must not "crash" on invalid input
Make sure that your program runs without errors or warnings.
Run your program enough times to verify its correctness.
Here is testscore:
import java.util.Scanner;
public class TestScore { public static void main(String[] args) { Scanner stdIn = new Scanner(System.in); double score = -1; System.out.print("Please enter a test score [0, 100] : "); System.out.println("The valid score entered was " + score); } }
