Write an exception class named InvalidTestScore. Modify the TestScores class you wrote in Part I so that it throws an InvalidTes

tScore exception if any of the test scores in the array are invalid. Test your exception in a program (in a subclass located in the same file). Your program should prompt the user to enter the number of test scores, and then ask for each test score individually. Then, it should print the average of test scores. If the average method throws an InvalidTestScore exception, the main method should catch it and print "Invalid test score."

package testscores;

import java.util.ArrayList;

import java.util.List;

public class TestScores {

public List<Integer> scorearray=new ArrayList<>();

public TestScores(List<Integer> scores) throws InvalidTestScore{

this.scorearray=scores;

for(int i=0;i<scorearray.size();i++){

if(scorearray.get(i)>100 || scorearray.get(i)<0){

throw new InvalidTestScore(this.scorearray.get(i));

}

}

}

public double average(){

int tot=0;

for(int i=0;i<this.scorearray.size();i++){

tot=tot+this.scorearray.get(i);

}

return tot*(1.0)/(this.scorearray.size());

}

class InvalidTestScore extends Exception

{

private double amount;

public InvalidTestScore(int Score)

{

System.out.println("Invalid Score "+Score);

#include<stdio.h>//defining header file

int AND(int x,int y) //defining a method AND that hold two variable in its parameter

{

if(x==1 && y==1)//defining if block to check x and y value is equal to 1

{

return 1;//return value 1

}

else //defining else block

{

   return 0;//return value 0

}

}

int OR(int x,int y)//defining method OR that hold two variable in its parameter

{

if(x==0&&y==0)//defining if block to check x and y value is equal to 1

{

return 0;//return value 0

}

else //defining else block

{

   return 1;//return value 1

}

}

int main()//defining main method

{

int a,b,c;//defining integer variable  

int k=1;//defining integer variable k that holds a value 1

while(k<=8)//defining while loop for 8 time input

{

printf("Please insert 3 numbers in (0 0r 1):\n ");//print message

scanf("%d%d%d", &a, &b, &c);//input value

k++;//increment the value of k by 1

printf("value: %d\n",AND(OR(a,b),c));

}

return 0;

}

Explanation:

In the above-given C language code two methods "AND and OR" is declared, holds two integer variable "x and y" in its parameters, inside the method a conditional it used that can be defined as follows:

  • In the AND method, inside a conditional statement, if block check x and y both value is same that is 1 it will return 1 or it will goto else block in this it will return value 0.      
  • In the OR method, inside a conditional statement, if block check x and y both value is the same, that is 0 it will return 0 or it will goto else block in this it will return value 1.
  • In the main method, four integers "a,b,c, and k" is declared in which variable "a, b, c" is used in the loop for 8 times input values from the user and print method is used to call the method and prints its return values.
