Как правильно в java добавить класс?

Подскажите пожалуйста как исходя из кода добавить protocol в код ?
тоесть ( protocol:id:meta ) 366:20:2

Ядро - на котором запускаеться плагин, кусок кода > GlobalBlockPlatte.java
public static int getOrCreateRuntimeId(int protocol, int legacyId) throws NoSuchElementException {
        switch (protocol) {
            // Versions before this doesn't use runtime IDs
            case 223:
            case 224:
                return legacyToRuntimeId223.get(legacyId);
            case 261:
                return legacyToRuntimeId261.get(legacyId);
            case 274:
                return legacyToRuntimeId274.get(legacyId);
            case 281:
            case 282:
                return legacyToRuntimeId282.get(legacyId);
            case 291:
                return legacyToRuntimeId291.get(legacyId);
            case 313:
                return legacyToRuntimeId313.get(legacyId);
            case 332:
                return legacyToRuntimeId332.get(legacyId);
            case 340:
                return legacyToRuntimeId340.get(legacyId);
            case 354:
                return legacyToRuntimeId354.get(legacyId);
            case 361:
                return legacyToRuntimeId361.get(legacyId);
            default: // 388+
                return getOrCreateRuntimeId(protocol, legacyId >> 4, legacyId & 0xf);
        }
    }


В этот код нужно добавить до функции borderBlock.getId() кусок функции protocol
