How can i change this to String in java

Question

in my program, i have capkTable Java class which is a String. In another class, i want to get a data, so i can use appState.capkTable.setCapki(data[i+3]). knowing fully well that (data[i+3]) is a byte.

How can i convert it to String?

what i did is this :

byte[] testing = new byte [(data[i+3])];
int tagDataLength = 0;
appState.capkTable.setCapki(StringUtil.toString(AppUtil.removeTailF(ByteUtil.bcdToAscii(testing,  0, tagDataLength))));

i don't know if i am doing it the right way..cos, instead of getting a value, it's returning java.lang.NullPointerException

appState.capkTable.setCapki(String.valueOf(data[i+3])); – Eldar Budagov Jul 20 '16 at 12:50 — Eldar Budagov, Jul 20 '16 at 12:50

Try replacnig this

StringUtil.toString(AppUtil.removeTailF(ByteUtil.bcdToAscii(testing,  0, tagDataLength))));

With this:

String.valueOf(AppUtil.removeTailF(ByteUtil.bcdToAscii(testing,  0, tagDataLength))));
