# Display prime number # Java program to display prime number

Today’s we learn about the prime numbers, A prime number is a natural number greater than 1 which are divisible by only 1 and itself. For example 2, 3, 5, 7, 11…  are prime numbers because they can neither be divided nor is a result of the multiplication.
To understand this program you should have the knowledge of for loop, if-else statements and break statement.

```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 any number:");
//capture the input in an integer
int num=scan.nextInt();
scan.close();
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 a Prime Number");
else
System.out.println(num + " is not a Prime Number");
}
}
```

### Program Output:

```Enter any number:
19
19 is a Prime Number

Enter any number:
6
6 is not a Prime Number
```

I hope this post helps you to understand Prime numbers and its implementation in Java programming language.

Keep coding 🙂
