How to Base64 Encode a String in Java

Quick solution

In short, you can just do this:

`1`	`new String(Base64.getEncoder().encode(bytes));`

Examples and an explanation

In Java 8 and above, you just need to import the Base64 class:

`1`	`import java.util.Base64;`

Then use the Base64 static methods as follows:

byte[] encodedBytes = Base64.getEncoder().encode("Test".getBytes());
System.out.println("encodedBytes " + new String(encodedBytes));

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

If you want to directly encode a string and get the result as an encoded string:

1
2

String encodeBytes = Base64.getEncoder()
    .encodeToString(("Your String").getBytes());
