Base64 Encode And Decode In Java

In this blog, you will learn about base64 encode and decode simple understanding in java.

Base64 Encoding

Base64 is an encoding method, where any data/images/audio file can be converted to binary data. And converted data can pass over the network without any data/image/audio loss

Base64 Decoding

This method is revers of base64 encoding, when received at other end, through network. Decode it and process data/image/audio files for the next specific requirement

Base64 encoding in Java

String plainText = "TestString";
byte[] encodedBytes = Base64.getEncoder().encode(plainText.getBytes(StandardCharsets.UTF_8));
String encodedString = new String(encodedBytes);
System.out.println(encodedString);

Base64 decoding in Java

byte[] decodedBytes = Base64.getDecoder().decode(encodedBytes);
String decodedString = new String(decodedBytes);
System.out.println(decodedString);
