Private warp help

I want players to be able to set warps, warp to those warps, delete the warps, and list them. I have this so far. The /delwarp command doesnt work, so I need help with all this:
How to list the warps
How to delete the warps
How to add a 10 second delay before teleport if anyone is within 10 blocks of player
How to kill player if they try to warp while in air for more than 1 second
How to make the player immune from damage and unable to attack for 5 seconds after warping
How to cancel warp if player moves within 10 seconds if the player is in 10 blocks.

Code:java

 
if(commandLabel.equalsIgnoreCase("setwarp")){
             if(args.length == 0){
                 player.sendMessage(ChatColor.GOLD + "Please name your warp!");
             } else if(args.length == 1){
                 int warpAmount = getConfig().getInt(player.getName() + ".Number-Of-Warps");
                 if(player.hasPermission("g.warp5")){
                     if(warpAmount == 5){
                         player.sendMessage("You have reached your warp maxium!");
                         return false;
                     }
                 }
             Location warp = player.getLocation();
             getConfig().set(player.getName() + "." +  args[0] + ".X", warp.getX());

                   player.teleport(PersonalWarp);
                   player.sendMessage(ChatColor.GOLD + "You can't attack for 10 seconds.");
             }
         }else if(commandLabel.equalsIgnoreCase("listwarp")){
             if(args.length == 0){
                 if(!getConfig().contains(player.getName() + ".")){
                 player.sendMessage(ChatColor.GRAY + "-----" + ChatColor.GOLD + "Your Warps" + ChatColor.GRAY + "-----");
             }
 
         }else if(commandLabel.equalsIgnoreCase("delwarp")){
             if(args.length == 0){
                 player.sendMessage(ChatColor.GOLD + "Specify a warp first!");
             } else if(args.length == 1){
                 if(!getConfig().contains(player.getName() + "." +  args[0])){
                   getConfig().set(player.getName() + "." + args[0], args[0] == null);
                   saveConfig();
                   player.sendMessage(ChatColor.GRAY + args[0] + ChatColor.GOLD + " deleted successfully.");
                 }
             }
         }
 

Any code to make this would help, I have been trying and can't figure it out.

Thanks what about for the other stuff i need help with?

You are checking if the config does not contain the warp, then trying to delete it.

 

What to do instead?

 

Remove the !

 

You have made countless help threads that can be solved with even basic use of logic or beginner Java knowledge, please learn Java before trying to deploy a program written in it.
