Java program to test the Prime number.
import java.util.*;
class Prime {
public static void main(String args[]) {
int flag, x, i;
flag = 0;
int a[] = new int[7];
for (x = 0; x < args.length; x++) {
a[x] = Integer.parseInt(args[x]);
for (i = 2; i < (a[x] / 2); i++) {
if ((a[x] % i) == 0) {
break;
} else flag = 1;
}
if (flag == 1)
System.out.println(a[x] + " is a prime no ");
else
System.out.println(a[x] + " is not a prime no ");
flag = 0;
}
}
}
