Composite Number is a number which have more than two factors.

Example 1: 4 have three factors (1,2,4). Hence it is a Composite Number.

Example 2: 12 have six factors (1,2,3,4,6,12). Hence it is a Composite Number.

        Scanner sc=new Scanner(System.in);
        System.out.print("Enter a number: ");
        n=sc.nextInt();
        for(int i=1;i<=n;i++)
        {
            if(n%i==0)
