Interpretation of the technical principles of the Angular Base64 framework in the Java class library

Angular Base64 is a JavaScript class library for processing Base64 encoding and decoding. It provides a simple and effective way to process Base64 data. In the technical principles of Angular Base64, it uses a coding table composed of 64 characters to convert binary data into printed ASCII characters to achieve data encoding and decoding. This encoding table is made by combining ASCII characters, numbers, and some special characters, and each character corresponds to a 6 -bit binary number.During the Base64 encoding process, the binary data of each three bytes re -combined into four 6 -bit groups, and then converted these groups to the corresponding ASCII characters. In Java, the relevant library can be used to process the base64 encoding and decoding.The following is a sample code that shows how to use the Base64 library that comes with Java to use the base64 encoding and decoding: import java.util.Base64; public class Base64Example { public static void main(String[] args) { // String to be coded String Input = "Hello, World!"; // Code the string to Base64 String encodedString = Base64.getEncoder().encodeToString(input.getBytes()); System.out.println("Encoded String: " + encodedString); // Decoding base64 as string byte[] decodedBytes = Base64.getDecoder().decode(encodedString); String decodedString = new String(decodedBytes); System.out.println("Decoded String: " + decodedString); } } Run the above code and get the following output: Encoded String: SGVsbG8sIOS4lueVjCEh Decoded String: Hello, the world! By using Base64 libraries, we can easily perform Base64 encoding and decoding to meet different needs.
