Which of these methods of Byte wrapper can be used to obtain Byte object from a string?OptionsgetString()toString()decode()encode()

The method that can be used to obtain a Byte object from a string in Java is decode(). The decode() method of Byte wrapper class is used to create a new Byte object by parsing the string. It is important to note that the string must contain a valid representation of a byte, otherwise a NumberFormatException will be thrown.

Here is a step by step guide on how to use it:

1. Declare and initialize a string that contains a valid representation of a byte. For example: String str = "10";

2. Call the decode() method on the Byte wrapper class and pass the string as an argument. For example: Byte b = Byte.decode(str);

3. Now, the variable 'b' holds the Byte object that represents the byte value contained in the string.

Please note that neither getString(), toString() nor encode() methods can be used to obtain a Byte object from a string. The toString() method is used to convert a Byte object to a string, not the other way around. And getString() and encode() are not methods of the Byte wrapper class in Java.
