2 byte array in Little Endian to int without java.nio.*

Question

I want to convert 2byte array in Little Endian to Int without using java.nio.*. How can I accomplish this?

With regards

Answer 1

This should do the trick int val = (anArray[1] & 0xff) << 8 + (anArray[0] & 0xff);

Answer 2

Just came across this post and realised that the accepted answer will not work correctly because + has a higher precedence than <<.

Therefore it should be int val = ((anArray[1] & 0xff) << 8) + (anArray[0] & 0xff); instead.

Answer 3

you have 2 Byte means 16 bit because in Little indian The least significant 16-bit unit stores the value you can use bitvise operations in java
