This program will prompt user to enter a number and then it will check and display whether the input number is prime or not.
Import java.util. Scanner ;
class PrimeCheck
{
public static void main( String args[])
{
int temp;
boolean isPrime= true ;
Scanner scan= new Scanner( System .in ); System .out .println( "Enter a number for check:" ); //capture the input in an integer
int num=scan.nextInt();
for ( int i= 2; i<=num/ 2; i++)
{
temp=num%i; if (temp== 0)
{
isPrime= false ; break ; } } // If isPrime is true then the number is prime else not if (isPrime)
System .out .println(num + " is Prime Number" );
else System .out .println(num + " is not Prime Number" );
}
}
class PrimeCheck
{
public static void main( String args[])
{
int temp;
boolean isPrime= true ;
Scanner scan= new Scanner( System .in ); System .out .println( "Enter a number for check:" ); //capture the input in an integer
int num=scan.nextInt();
for ( int i= 2; i<=num/ 2; i++)
{
temp=num%i; if (temp== 0)
{
isPrime= false ; break ; } } // If isPrime is true then the number is prime else not if (isPrime)
System .out .println(num + " is Prime Number" );
else System .out .println(num + " is not Prime Number" );
}
}
