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...
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...
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JAVA中,将附件对象转换为ByteArray可以通过以下步骤实现: 1. 首先,需要使用Java的文件处理类来读取附件文件。可以使用`FileInputStream`类来读取文件内容。例如,假设...
Using the Writer Class for String to Byte Array Conversion Another way of converting string to byte array in Java when the encoding class is not known is by using the following snippet: public static byte[] ConvertStringToBytes(string input) { MemoryStream stream = new MemoryStream(); using...
