.getBytes()

The .getBytes() method encodes a string into an array of bytes that represents the characters in the string.

Syntax

byte[] byteArray = str.getBytes();

• byteArray is a byte array that stores the byte representation of the string.
• str is the string being converted to bytes.

Example

The example below demonstrates the use of the .getBytes() method:

// Example.java
import java.util.*;

public class Example {
  public static void main(String[] args) {
    String myStr = "codeacademy.com";
    byte[] myByteArray = str.getBytes();
    System.out.println(Arrays.toString(byteArray));
  }
}

This outputs the following:

[99, 111, 100, 101, 97, 99, 97, 100, 101, 109, 121, 46, 99, 111, 109]
