Solved Rainbow Lucky Block

The armor stand I want has a skull on its head and I want the armor stand to find the block on its head and replace it with another colored glass.

This Code Not Working.

Code:

    @SuppressWarnings({ "unlikely-arg-type", "deprecation" })
    @Override
    public void onEnable() {
        System.out.println("&e&lEklenti Baslatildu Usagum Da. &b&lBy: 1Ripeness ");
        this.getCommand("getskull").setExecutor(new CommandExecuter());
        this.getCommand("getskullUUID").setExecutor(new CommandExecuter());
        this.getCommand("tlb").setExecutor(new CommandExecuter());
        this.getCommand("tluckyblock").setExecutor(new CommandExecuter());
      
        Bukkit.getScheduler().scheduleAsyncRepeatingTask(this, new Runnable() {
            @Override
            public void run() {
              
                for(World w : getServer().getWorlds()) {
                    for(Entity a : w.getEntities()) {
                        if(a instanceof ArmorStand) {
                            ArmorStand as = (ArmorStand) a;
                            Block b = (Block) as.getLocation().add(0, 1.2, 0).getBlock();
                            if(b.equals(Material.STAINED_GLASS) && as.getEquipment().getHelmet().getItemMeta().getDisplayName() == "§fLucky Block (Rainbow)") {
                              
                                if(b.equals(b.getData() == 15)) {
        b.setTypeIdAndData(95, (byte)9, true);
                                } else if(b.equals(b.getData() == 9)) {
        b.setTypeIdAndData(95, (byte)14, true);
                                } else if(b.equals(b.getData() == 14)) {
        b.setTypeIdAndData(95, (byte)1, true);
                                } else if(b.equals(b.getData() == 1)) {
        b.setTypeIdAndData(95, (byte)2, true);
                                } else if(b.equals(b.getData() == 2)) {
        b.setTypeIdAndData(95, (byte)4, true);
                                } else if(b.equals(b.getData() == 4)) {
        b.setTypeIdAndData(95, (byte)5, true);
                                } else if(b.equals(b.getData() == 5)) {
        b.setTypeIdAndData(95, (byte)11, true);
                                } else if(b.equals(b.getData() == 11)) {
                                    b.setTypeIdAndData(95, (byte)15, true);
                                }
                              
                            }
                          
                          
                          
                        }
                    }}
              
              
            Bukkit.broadcastMessage("aaA");  
            }
        }, 60, 60);
      
      
      
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
        //getServer().getPluginManager().registerEvents(new AListener(), this);
    }
