In this article, we will examine some example to convert String to Char array vise verse.

This article shows you how to use the JDK1.5 String.format() and Apache Common Lang to left or right pad a String in Java.
This article shows you how to format a string in Java, via String.format(). We will examine how to control String format with argument, how to format Integer, Floating Points as string
In Java, we can use str.getBytes(StandardCharsets.UTF_8) to convert a String into a byte[]. And we can use new String(bytes, StandardCharsets.UTF_8) to convert byte[] to a String.
In Java, we can use new String(bytes, StandardCharsets.UTF_8) to convert a byte[] to a String. For text or character data, we use new String(bytes, StandardCharsets.UTF_8) to convert the byte[] to a String directly. 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.
