You miss the array index in the if condition:

argv[i].equals("-h")

argv is an entire array. What you are trying to match, is the entire content of the array with the string -h. Try doing this:

public static void main(String[] argv) throws Exception
{

    System.out.println("1");
    for(int i=0;i<argv.length;i++)
    {
        if (argv[i].equals("-h"))
        {
            System.out.println("-ip   target ip address\n");
            System.out.println("-t    time interval between each scan in milliseconds\n");
            System.out.println("-p    protocol type [UDP/TCP/ICMP]\n");
            System.out.println("-type scan type [full,stealth,fin,ack]\n");
            System.out.println("-b    bannerGrabber status\n");

        }
     }
}

Side Note: This previous SO post might also be worth going through.

You try to compare String[] with String.

Try instead:

    if (argv[i].equals("-h"))

You are comparing an array with a string. Change it to:

   if (argv[i].equals("-h"))
