String text = Integer.toBinaryString(ch) // converts ASCII value to Binary If you want to find the binary of a singular alphabet, then you can make use of Ascii codes as given below:

This Base64 encode decode string is still widely use in decode, convert base64 encoded string back to byteīyte decode = Base64.getDecoder().decode(s) String s = Base64.getEncoder().encodeToString(bytes) encode, convert byte to base64 encoded string However, for cases that byte is holding the binary data like the image or other non-text data, the best practice is to convert the byte into a Base64 encoded string.īyte bytes = Files.readAllBytes(Paths.get("/path/image.png")) Convert byte to String (binary data)įor text or character data, we use new String(bytes, StandardCharsets.UTF_8) to convert the byte to a String directly. String s = new String(bytes, StandardCharsets.UTF_8) Public User(String firstName, String lastName) else if (user.In Java, we can use new String(bytes, StandardCharsets.UTF_8) to convert a byte to a String.īyte bytes = "hello".getBytes(StandardCharsets.UTF_8) We'll create a User model object and a Repository singleton class that works with User objects and exposes lists of users and formatted user names.Ĭreate a new file called User.java under app/java/ and paste in the following code: public class User String String lastName Minimum SDK can be of any value, it will not affect the outcome. If you're using Android Studio, create a new project with the No Activity template. If you're using IntelliJ IDEA, create a new Java project with Kotlin/JVM.

Android Studio Bumblebee or IntelliJ IDEA.

You should already be familiar with Java. In doing so you will learn the following Kotlin language features and concepts: You will learn how to convert Java to Kotlin. Then we'll take a look at the converted code and see how we can improve it by making it more idiomatic and avoid common pitfalls.

We'll start with a couple of Java classes that you'll convert to Kotlin using the IDE. This codelab is suited to any developer that uses Java who is considering migrating their project to Kotlin. You'll also learn what the Kotlin language conventions are and how to ensure that the code you're writing follows them.

In this codelab, you'll learn how to convert your code from Java to Kotlin.
