What is the difference between declaration and definition?
Declaration of a variable is for informing to the compiler the following information: name of the variable, type of value it holds and the initial value if any it takes.
Whereas, Definition of a variable says where the variable gets stored.
What is the purpose of type declaration?
The type declaration statement overrides the implicit type rules in effect. You can use a type declaration statement that confirms the type of an intrinsic function. The appearance of a generic or specific intrinsic function name in a type declaration statement does not cause the name to lose its intrinsic property.

For a variable, a definition is a declaration which allocates storage for that variable. Initialization is the specification of the initial value to be stored in an object, which is not necessarily the same as the first time you explicitly assign a value to it.

For decimal values, this data type is generally the default choice.
What is print () in Java?
