Hi guys, check this for mistakes.

 

BlockClass:

public class CraftClass extends Block {
    public CraftClass() {
        super(Material.IRON);
        this.setUnlocalizedName("Craft");
        this.setRegistryName("Craft");
        this.setCreativeTab(CreativeTabs.REDSTONE);
    }

    @Override
    public boolean onBlockActivated(World world, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, @Nullable ItemStack heldItem, EnumFacing side, float hitX, float hitY, float hitZ) {

        BlockPos bp = new BlockPos(pos.getX(), pos.getY() + 1, pos.getZ());
        Block b = world.getBlockState(bp).getBlock();
        if(b == Blocks.DRAGON_EGG)
        {
            playerIn.addExperience(131231);
        }
        return super.onBlockActivated(world, pos, state, playerIn, hand, heldItem, side, hitX, hitY, hitZ);
    }

mainClass:

@Mod(modid = settings.MODID, version = settings.VERSION, name = settings.NAME)
public class multistructs {

    public Main instance = new Main();


    public static Block craft = new CraftClass();
    @EventHandler
    public void init(FMLInitializationEvent event)
    {

    }
    @EventHandler
    public void preinit(FMLPreInitializationEvent event)
    {
        GameRegistry.register(craft);
    }
    @EventHandler
    public void postinit(FMLPostInitializationEvent event)
    {
