'How to get the JAR file for sun.misc.BASE64Encoder class?

I have some code in my Activity class that uses sun.misc.BASE64Encoder class. But it is showing java.lang.NoClassDefFoundError : sun.misc.BASE64Encoder. Do I need the jar? Where can I download it from?

Since Java 8 you can use java.util.Base64 class:

byte[] original = "Base64".getBytes(StandardCharsets.UTF_8);

// encode
byte[] toBase64 = Base64.getEncoder().encode(original);

// decode
byte[] fromBase64 = Base64.getDecoder().decode(toBase64);

// output
System.out.println(new String(toBase64)); //QmFzZTY0
System.out.println(new String(fromBase64)); //Base64
System.out.println(Arrays.equals(original, fromBase64)); //true

  1. Just add rt.jar to the build path of the project from path C:\Program Files\AdoptOpenJDK\jdk-8.0.202.08\jre\lib
  2. Copy the jar and paste in the libraries folder of the project.

For me it is resolved with simple steps, I was using Java11 JDK.As, in this version Base64 classes are deprecated, we are getting this issue. Changing to Java 8 solved the issue. Steps: In Eclipse,

  1. Go to, Windows-> Preferences-> Installed JREs
  2. Add-> select JDK8 or lesser version of JDK->Add
  3. Make it as default JDK by selecting this JDK
  4. Apply and Close

And, Done.

Thank you.

It's available in rt.jar, that comes with Sun java runtimes.

In 1.5.0_06 : jre\lib\rt.jar
