If you need Java code to convert a file to a byte array and then convert it back, this will work for you! First, to convert a file to byte array, ByteArrayOutputStream class is used. This class implements an output stream in which the data is written into a byte array. The buffer ...
ObjectInputStream ois = null; try { //写入字节流 ByteArrayOutputStream out = new ByteArrayOutputStream(); obs = new ObjectOutputStream(out); obs.writeObject(obj); //分配内存,写入原始对象,生成新对象 ByteArrayInputStream ios = new ByteArrayInputStream(out.toByteArray()); ...
