Question

Write an application that displays a series of at least five student ID numbers (that you have stored in an array) and asks the user to enter a numeric test score for the student. Create a ScoreException class, and throw a ScoreException for the class if the user does not enter a valid score (less than or equal to 100). Catch the ScoreException, display the message Score over 100, and then store a 0 for the student’s score. At the end of the application, display all the student IDs and scores. g

Answer 1

See explaination for the program code

Step-by-step explanation:

// ScoreException.java

class ScoreException extends Exception

{

ScoreException(String msg)

{

super(msg);

}

}

// TestScore.java

import java.util.Scanner;

public class TestScore

{

public static void main(String args[]) throws ScoreException

{

Scanner sc = new Scanner(System.in);

int studentId[] = { 1201, 1202, 1203, 1204, 1205 };

int scores[] = new int[5];

int score = 0;

for(int i = 0; i < studentId.length; i++)

{

try

{

System.out.print("Enter a numeric test score for the student"+(i+1)+" of Id "+studentId[i]+" : ");

score = sc.nextInt();

if(score < 0 || score > 100)

{

scores[i] = 0;

throw new ScoreException("Input should be between 1 and 100");

}

else

{

scores[i] = score;

}

}

catch(ScoreException ex)

{

System.out.println("\\"+ex.getMessage()+"\\");

}

}

//displaying student details

System.out.println("\\\\Student Id \t Score ");

System.out.println("=============================");

for(int i = 0; i < studentId.length; i++)

{

System.out.println(studentId[i]+"\t\t"+scores[i]);

}

}

}
