What are methods to convert data (ints, strings) to bytes in Java? I am looking for methods other than using the Serializable class. I researched and found things like ByteOutputStream.
Can I just parse strings and ints to a byte data type?
Any suggestions?
Have a look at DataInputStream and DataOutputStream, they convert all Java data types to bytes and read/write to an underlying Input/OutputStream.
If you need to read or write ints, longs etc.. to a file, then these are the classes for you.
If instead you are just interested in how to convert then to bytes for other purposes, have a look at the source code of those classes, they convert to big-endian.
