How do I decode a Base64 encoded binary?

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

        // 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
