c++;

}

return (c>2);

}

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter 10 numbers..");

int a[]=new int[10];

for(int i=0;i<10;i++)

a[i]=sc.nextInt();

for(int i=0;i<10;i++)

{

if(isComposite(a[i]))

System.out.println(a[i]+" is composite. ");
