Thank you -------------------------------------------- import java.util.Scanner; public class Lab4a { public static void main(String[] args) {

Explanation / Answer

Answer:

Include the below code and changes and run the code :

import java.util.Scanner;
public class Lab4a {
public static void main(String[] args) {
Scanner scnr =new Scanner(System.in);
int userNum;
boolean isPrime = true;
  
System.out.println("Enter a positive integer or 0 to exit:");
userNum = scnr.nextInt();
if (userNum==0)
System.exit(0);
if (userNum < 0) {
System.out.println("Please enter a positive integer.");
System.exit(1);
}
for(int mult = 2; mult <= userNum/2 || (userNum == 1) || (userNum == 2) || (userNum == 3); mult++) {
if ((userNum == 1) || (userNum == 2) || (userNum == 3)) {
System.out.println(userNum+ " is prime.");
System.out.println("Enter a positive integer or 0 to exit:");
userNum = scnr.nextInt();
}
if (userNum==0)
System.exit(0);
if (userNum < 0) {
System.out.println("Please enter a positive integer.");
System.exit(1);
}
if (userNum % mult==0)
isPrime = false;
else
isPrime = true;
if ((isPrime) && (userNum != 1) && (userNum != 2) && (userNum != 3)) {
System.out.println(userNum + " is prime.");
System.out.println("Enter a positive integer or 0 to exit:");
userNum = scnr.nextInt();
}
if (isPrime == false && (userNum != 1) && (userNum != 2) && (userNum != 3)) {
System.out.println(userNum + " is not prime.");
System.out.println("Enter a positive integer or 0 to exit:");
userNum = scnr.nextInt();
}
}

}
}
