In Java, you can convert a string into an array of its constituent bytes by calling myString.getBytes().
What's the equivalent of this in Kotlin?

To convert a string to byte array in Kotlin, use String. toByteArray() method. String. toByteArray() method returns a Byte Array created using the characters of the calling string.
The method getBytes() encodes a String into a byte array using the platform's default charset if no argument is passed. We can pass a specific Charset to be used in the encoding process, either as a String object or a String object.
To create a Byte Array in Kotlin, use arrayOf() function. arrayOf() function creates an array of specified type and given elements.
Use the extension String.toByteArray() - which means you will write myString.toByteArray(). Note it defaults to UTF-8 encoding, but you can override this by providing an additional argument.

For Kotlin use String.toBytesArray(), it will be same as String.getBytes() in Java.
