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) 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)
