[Java] Base64 Encoding, Decoding Examples

1. Base64 Encoding, Decoding with java.util.Base64

1 2 3 4 5 6 7 8 9

static void testBase64Jdk() { String s = "Test Str"; Encoder e = java.util.Base64.getEncoder(); Decoder d = java.util.Base64.getDecoder(); byte[] eb = e.encode(s.getBytes()); byte[] db = d.decode(eb); System.out.println(new String(eb)); System.out.println(new String(db)); }

Result:

VGVzdCBTdHI=
Test Str

2. Base64 Encoding, Decoding with org.apache.commons.codec.binary.Base64

static void testBase64Commons() { String s = "Test Str"; byte[] eb = Base64.encodeBase64(s.getBytes()); byte[] db = Base64.decodeBase64(eb); System.out.println(new String(eb)); System.out.println(new String(db)); }

Result:

VGVzdCBTdHI=
Test Str
