package org.kodejava.example.commons.codec;
import org.apache.commons.codec.binary.Base64;
import java.util.Arrays;
public class Base64Decode {
public static void main(String[] args) {
String hello = "SGVsbG8gV29ybGQ=";
//
// Decode a previously encoded string using decodeBase64 method and
// passing the byte[] of the encoded string.
//
byte[] decoded = Base64.decodeBase64(hello.getBytes());
//
// Print the decoded array
//
System.out.println(Arrays.toString(decoded));
//
// Convert the decoded byte[] back to the original string and print
// the result.
//
String decodedString = new String(decoded);
System.out.println(hello + " = " + decodedString);
}
}
The result of our code is:
[72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100] SGVsbG8gV29ybGQ= = Hello World
