Question

Implement a Java program using simple console input & output and logical control structures such that the program prompts the user to enter 5 integer scores between 0 to 100 as inputs and does the following tasks

• For each input score, the program determines whether the corresponding score maps to a pass or a fail. If the input score is greater than or equal to 60, then it should print “Pass”, otherwise, it should print “Fail”.
• After the 5 integer scores have been entered, the program counts the total number of passes as well as the total number of failures and prints those 2 count values with appropriate messages like “Total number of passes is: <count value1>” &  “Total number of failures is: <count value2>”.
• After the 5 integer scores have been entered, the program finds the highest score as well as the lowest score and prints those 2 values with appropriate messages like “Highest score is: <value1>” &  “Lowest score is: <value2>”.
• The program checks whether an input score is a number between 0 - 100 or not. If the input score value is otherwise or outside the above range, then it prints the error message saying “Invalid score” and prompts the user for a valid input.

import java.util.ArrayList;
import java.util.Scanner;

public class Problem3 {

       public static void main(String[] args)
       {

           int number;
          
           Scanner scanner = new Scanner(System.in);
          
           System.out.println("Enter each of the 5 scores as an integer between 0 and 100.");
           ArrayList<Integer> scoreList = new ArrayList<Integer>();   //Create ArrayList to store scores in
          
           //Prompt the user to enter 5 integer scores and puts them in an ArrayList
  

       }

   }

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

import java.util.ArrayList;
import java.util.Scanner;

public class Problem3 {

public static void main(String[] args)
{

int number;
  
Scanner scanner = new Scanner(System.in);
  
System.out.println("Enter each of the 5 scores as an integer between 0 and 100.");
ArrayList<Integer> scoreList = new ArrayList<Integer>(); //Create ArrayList to store scores in
  
//Prompt the user to enter 5 integer scores and puts them in an ArrayList
int ct1=0,ct2=0;
for(int i=0;i<5;i++)
{
System.out.print("Enter a score: ");
  
number=scanner.nextInt();
while(number<0||number>100)
{
System.out.println("Invalid score: ");
  
System.out.print("Enter a score: ");
  
number=scanner.nextInt();
}
scoreList.add(number);
if(number<60)
{
System.out.println("FAIL");
ct1++;
  
}
else
{
System.out.println("PASS");
ct2++;
}
}
int low=scoreList.get(0),high=scoreList.get(0);
for(int i=0;i<5;i++)
{
if(low>scoreList.get(i))
low=scoreList.get(i);
if(high<scoreList.get(i))
high=scoreList.get(i);
  
}
System.out.println("Total number of passes is: "+ct2);
System.out.println("Total number of failures is: "+ct1);
System.out.println("Highest score is: "+high);
System.out.println("Lowest score is: "+low);
  
}

}

Kindly revert for any queries

Thanks.
