byte[] bytes = string.getBytes();此外，Base64.getDecoder().decode()方法可以将字符串转换为字节数组。例如：字符串 string = " Java Tutorials";使用Base64解码方法将字符串转换为字节数组：byte[] bytes = Base64.getDecoder().decode(string);通过以上步骤，可以将字符串或Base64解码字符串转换...
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...
This class implements an output stream in which the data is written into a byte array. The buffer automatically grows as data is written to it. The data can be retrieved usingtoByteArray()andtoString(). Closing aByteArrayOutputStreamhas no effect. The methods in this class can be called ...
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()....
