+
+- String is capitalised due to it being a class.
+
+### Scope
+
+- Parameter can only be accessed from the body of the method in which it is declared. We can say its **scope** is restricted to the body of the method.
+- The scope of a field variable is the body of the class it is declared in.
+
+### Lifetime and Accessor Methods
+
+- Lifetime of a parameter of a method is the duration of a particular call to a method.
+- Value is lost when call completed
+- Lifetime of an objects field variable is the lifetime of the object itself
+- Accessor method allows access to the value of a field without changing the state of an object
