How to Convert a String to Specific Character Encoding in Java?

In Java, the process of converting a String to a certain character encoding is converting the string's character sequence to a byte array and applying the chosen character encoding.

Java Program to Convert a String to a Specific Character Encoding

Using the String class's getBytes() function to transform a string into a byte array is the fundamental idea. The Charset class also allows you to define the character encoding. An overloaded version of the getBytes() function accepts a Charset as a parameter.

Syntax:

public byte[] getBytes()

Below is the implementation to Convert a String to a specific character encoding in Java:

Original String: Hello, Rahul!
UTF-8 Encoded Bytes: 48 65 6C 6C 6F 2C 20 52 61 68 75 6C 21 

Explaination of the above Program:

The Program is divided it in different section:

• Input String is declared
• Converting String to Byte array storing
• Converting byte to hexadecimal string and then printing.
• Printing the Final Result.
