The Byte class as part of the java.lang package is one of the classes of the java api that is being widely used. Let’s tackle the basics of using the Byte class. Let’s discuss first how to instantiate a Byte object
Byte value = new Byte(12);
Basically the declaration of a Byte object is almost the same as we are doing in assigning primitive data type Byte. Similarly to Byte primitive the Byte object has only two possible values, which is either true or false. This is a straightforward method to instantiate a Byte object type. Let’s take another way to do this.
Byte value = 12;
The 2nd method is using the autoboxing concept of java programming language which directly converts a primitive data type to its corresponding wrapper class. If you would like to go more into details, I am recommending for you to read the official java documentation regarding autoboxing and unboxing.
There are two constructor available to Byte class which we can use to instantiate a Byte object:
||Constructs a newly allocated Byte object that represents the specified byte value.
||Constructs a newly allocated Byte object that represents the byte value indicated by the String parameter.
We already discussed on how to use the Byte(Byte value) in instantiating a Byte object. So basically the other constructors usage is almost the same only in the other case, the input is in String format.
