		plugin.getCommand("hello").setExecutor(this);
	}
	@Override
	public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if (!(sender instanceof Player)){
	sender.sendMessage("player only command");

}
Player p = (Player) sender ;

	p.sendMessage("hi");
	return true;
	

	}
}

please help me I can't find any help and I hope this can help any one

there's this format built into the spigot

TextComponent test= new TextComponent("hi");
	shopfood.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_TEXT,new ComponentBuilder("hi")).create() ));
p.spigot().sendMessage(test);

some sample code and it will so some text when hover on the text and heres the anwser

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if (!(sender instanceof Player)){
    sender.sendMessage("player only command");
    return true;

}
Player p = (Player) sender ;
TextComponent test= new TextComponent("hi");
    shopfood.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_TEXT,new ComponentBuilder("hi")).create() ));
p.spigot().sendMessage(test);
    return true;


    }
}

here's some sample code

TextComponent enter-var-name-here = new TextComponent(enter first text);
    shopfood.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_TEXT,new ComponentBuilder(enter-hover-text)).create() ));
p.spigot().sendMessage(enter-var-name-here);
