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

// Java Program to Convert a String 
// Specific Character Encoding
import java.nio.charset.Charset;

// Driver Class
public class StringToEncodingExample {
      // Main Function
    public static void main(String[] args) {
      
        // Create a sample string
        String originalString = "Hello, Rahul!";

        // Convert the string to bytes using a specific encoding
        byte[] utf8Bytes = originalString.getBytes(Charset.forName("UTF-8"));

        // Display the original string and the encoded bytes
        System.out.println("Original String: " + originalString);
        System.out.println("UTF-8 Encoded Bytes: " + bytesToHex(utf8Bytes));
    }

    // Method to convert byte array to hexadecimal string
    private static String bytesToHex(byte[] bytes) {
        StringBuilder hexStringBuilder = new StringBuilder();
      
        for (byte b : bytes) {
            hexStringBuilder.append(String.format("%01X ", b));
        }
        return hexStringBuilder.toString();
    }
}
