What Does Each Code Snippet Do?
```
a) Assume that the following method call is located in an overridden earnings method in
a subclass:
super.earnings()
b) Assume that the following line of code appears before a method declaration:
@Override
c) Assume that the following line of code appears as the first statement in a constructor’s body:
super(firstArgument, secondArgument);
```
a) This expression invokes the superclass’s original version of the earnings method as part of implementing the subclass’s earnings method.
b) This indicates to the compiler that the method being declared overrides a superclass method. The compiler then ensures that there is a method in the superclass with the same first line; otherwise, an error is reported.
c) This invokes the superclass constructor that takes two arguments of the appropriate types.
