someone can please ?

thanks !

public static void main(string[] argv) throws exception {      system.out.println("1");     for(int i=0;i<argv.length;i++)     {         if (argv.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");          } 

}

argv entire array. trying match, entire content of array 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");          }      } }
