Java program to get the contents of a given string as a byte array.

💻 Program Code

import java.util.Calendar;

public class Exercise {

  public static void main(String[] args)
    {
        String str = "This is a sample String.";

        // Copy the contents of the String to a byte array.
        byte[] byte_arr = str.getBytes();

        // Create a new String using the contents of the byte array.
        String new_str = new String(byte_arr);

        // Display the contents of the byte array.
        System.out.println("\nThe new String equals " +
            new_str + "\n");
    }
}
