converting byte array to float

[Curtis Nelson]

Hi,

Can somebody please supply me with some code to convert a 4-byte array into
a float? In C, you can just cast a float pointer to the byte pointer, but
no such mechanism exists in Java.

Thanks

DataInputStream dis = new DataInputStream(new
ByteArrayInputStream(the4byteArray));
float f = dis.readFloat();

However, if you originally read the 4 bytes from a file or some other input
stream, why not go back and change your program to read the float number
directly from that source? Wrap your input stream in a DataInputStream as
in the code above.
