Follow all instructions below:

Keep the program\'s code as simple as possible - begineer level with no advanced level Java concepts/skills

Write a program that asks the user for a number. The program should check the number to ensure that it is valid (if not, the user should enter a valid number to continue.) The program should print out all of the prime numbers from 2 up to the number, with up to 10 numbers per line. (Recall: A prime number is a number that is only divisible by itself and 1)The code should ask the user if they want to run the program again. You will need: 1. A scanner object to read 1. The user\'s numerical entry 2. The user\'s string response 2. Variables to store: 1. The user\'s entry (should be an integer) 2. The user\'s response (should be a string) 3. The number of primes (this will help to determine how many numbers are printed before moving to the next line) (Include additional variables as needed) 3. Several loops 1. A do...while loop to repeat the program. This loop will contain: 1. A while loop for input validation 2. A while loop to determine if the number is prime (this loop may contain a nested for loop to check primes from 2 up to the user\'s entry) An if statement to determine when to skip a line after 10 numbers has been printed 4. Lots of comments for documentation

Solution

Here is my solution in java :-

package com;
import java.util.*;
public class Prime {

   /**
   * @param args
   */
   public static void main(String[] args) {
       // TODO Auto-generated method stub
      
       int number=0; // number to take input from user
       String response; // input to take response from user
       Scanner sc;             // declaring scanner object
       int linc=0; //declaring int var to take care of line
       sc = new Scanner(System.in);      
boolean flag; // declaring boolean variable to know user wants to continue run program or not
   do{
      
   System.out.print(\"do you want to continue(Y/N): \");
   // sc.next();
   response = sc.next(); // asking user to give response
   if(response.equals(\"Y\")||response.equals(\"y\"))
   {
       System.out.print(\"Enter the number: \");
       while(!sc.hasNextInt()) //verifying if input is an integer or not
               {
                   System.out.println(\"invalid input\ try again\");
                   sc.next();
                   continue;  
               }
      
       number=sc.nextInt();
           String primeNumbers=\"\"; //declaring string which stores prime number
           int i=2;
           if(number>=2){
           while(i <= number) // while loop to determine prime number from 2 to number
      {           
   int counter=0;   
   for(int num =i; num>=1; num--) //prime number logic
   {
   if(i%num==0)
   {
       counter = counter + 1;
   }
   }
       if (counter ==2)
       {
       //Appended the Prime number to the String
           if(linc<10){
       primeNumbers = primeNumbers + i + \" \";
       linc++;
           }
           else
           {
               linc=1;
               primeNumbers+= \"\ \"+i+\" \"; //if linc value cross 10 then added \ to break the line and print prime numbers in new line
           }
       }
       i++;
   }  
   System.out.println(\"Prime numbers from 2 to num are :\");
   System.out.println(primeNumbers);
   }
           else{
               System.out.println(\"Number should be greater then or equal to 2\");
           }
   }
   else
       response= \"N\";
   flag = response.equals(\"N\");
     
}while(!flag);
   sc.close();
   }

}
