Introduction
In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..
Write a Java program to check whether the number is a prime number or not
import java.util.Scanner;
public class JavaLoopExcercise
{
public static void main(String[] args)
{
Scanner console = new Scanner(System.in);
int number;
System.out.print("Enter the positive integer ");
number = console.nextInt();
boolean flag = true;
for(int i = 2; i < number; i++)
{
if(number % i == 0)
{
flag = false;
break;
}
}
if(flag && number > 1)
{
System.out.println("Number is prime");
}
else
{
System.out.println("Number is not prime");
}
}
}
Result
