Read 4-Byte floating binary file with java

Question

I searched on the internet, I find just sthg related to read/write binary file int, short, byte but not for float.
Having a square matrix 100*100 stored as floating values as binary file, I would read its value in order to e.g. store them in 2D float array etc...
Any help plz

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();
