Question

please solve the problem by using Java

A prime number is a number greater than one that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a program that asks the user to enter a number that is greater than or equal to 2. If they enter a number less than two print an error message (and exit the program using the return statement). Otherwise print a message that indicates whether or not the number is primes

Explanation / Answer

PrimeNumber.java

public class PrimeNumber {

  
   public static void main(String[] args) {
       java.util.Scanner in = new java.util.Scanner(System.in);
       System.out.println("Please Enter a number greater than or equals to 2:");
       int inputNUmber = in.nextInt();
       if( inputNUmber < 2){
           System.out.println("Input number must be greater than 2");
       }
       boolean isPrime = true;
       //loop through the numbers one by one
       for(int i=2; i<=inputNUmber/2; i++){
           if(inputNUmber % i == 0){
               isPrime = false;
               }
           }
       if(isPrime){
           System.out.println("Given number is a prime number");
       }
       else{
           System.out.println("Given number is not a prime number");
       }

   }
  
}

Output:

Please Enter a number greater than or equals to 2:
45
Given number is not a prime number

Please Enter a number greater than or equals to 2:
37
Given number is a prime number
