Prime number is a number that is greater than 1 and divided by 1 or itself. For example 2, 3, 5, 7, 11, 13, 17.... are the prime numbers.
package javabox;
public class PrimeNumberExample {
public static void main(String[] args) {
int n=5;//Number to be checked
boolean isPrime=true;
int i,m=0;
m=n/2;
if(n==0||n==1){
System.out.println(n+" is not prime number");
}
else{
for(i=2;i<=m;i++){
if(n%i==0){
System.out.println(n+" is not prime number");
isPrime=false;
break;
}
}
if(isPrime) {
System.out.println(n+" is prime number");
}
}//end of else
}
}
Output -
5 is prime number
