Here is a preview of the final app:
In this program ,we check this number is prime number or not in java programming language..
PrimeNumber.java
import java.util.Scanner;
class Prime Number
{
public static void main(String args[])
{
int n;
int count=0; //division counter
Scanner sc=new Scanner(System.in);
System.out.print("Enter a number");
n=sc.nextInt();
for(int i=1;i<=n;i++)
{
if(n%i==0)
{
count++; //increment
}
}
if(count==2)
{
System.out.println(n+"is a Prime number");
}
else
{
System.out.println(n+"is Not Prime number");
}
}
}
