Class name: Prime

Member Methods:
void input(): to input a number
void checkprirne(): to check and display whether the number is prime or not.

Use a main function to create an object and call member methods of the class.

Answer 1

import java.util.*;
public class Prime 
{private int n; 
void input() 
{Scanner ob = new Scanner(System.in); 
System.out.println("Enter the number"); 
n = ob.nextInt(); 
)
void checkprime()
{int cnt = 0; 
for (int i = 1; i <= n; i++) 
{ if (n % i == 0) 
cnt++; 
) 
if (cnt == 2)System.out.println("The number is prime"); 
else System.out.println("The number is not prime"); 
) 
public static void main(String args[]) 
{ Prime C = new Prime(); 
C.input(); 
C.checkprime(); 
}}
