char - How to convert 4 bytes array to float in java

Question

I have a 4 bytes array which represent a float value. The bytes is read from network, for example, 3e 3f e3 a0. How can I convert it from byte[] to float in java?

Answer 1

In Java a char is 16-bit. If you mean you have a 4 byte values in little endian byte order which you need to convert to a float you can use ByteBuffer.

byte[] bytes = { }
float f = ByteBuffer.wrap(bytes).order(ByteOrder.LITTLE_ENDIAN).getFloat();
