Java provide ByteBuffer class to do the same.to convert any byte array, first we need to allocate 8 bytes using ByteBuffer’s static method allocate, then put byteArray using put method and flip bytebuffer. by calling getLong() method we can get long value of that byte array. private long...
private byte[] convertToByteArray(UUID uuid) { byte[] result = new byte[16]; long mostSignificantBits = uuid.getMostSignificantBits(); fillByteArray(0, 8, result, mostSignificantBits); long leastSignificantBits = uuid.getLeastSignificantBits(); fillByteArray(8, 16, result, leas...

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...
Java 中 byte 数组和 int 之间的转换源码: //byte 数组与 int 的相互转换 publicstaticintbyteArrayToInt(byte[]b) { returnb[3]&0xFF| (b[2]&0xFF)<<8| (b[1]&0xFF)<<16| (b[0]&0xFF)<<24; } publicstaticbyte[]intToByteArray(inta) { ...
To convert from string to byte array, use String.getBytes() method. Please note that this method uses the platform’s default charset. //String String string = "Java Tutorials"; //Convert string to byte[] byte[] bytes = string.getBytes(); Base64 class in Java 8 Base64.getDecoder()....
在上面的代码中,我们首先定义了一个名为convertFileToByteArray的静态方法,它接受一个File对象作为参数,并返回一个字节数组。在这个方法中,我们首先创建一个FileInputStream对象来读取文件的内容,然后使用read方法将文件内容读取到一个字节数组中,最后关闭流并返回字节数组。
