As just mentioned, Lady Macbeth eventually shows weakness and starts sleepwalking (Act 5, scene 1). Here we get a view into Lady Macbethâs unconscious mind and thereby her true feelings. Lady Macbeth seems to be fragile and vulnerable, and for the first time in the play we have sympathy for her.The sleepwalking is caused by Lady Macbethâs attempt to repress strong feelings of guilt. Another example is the murder of King Duncan, which is essential to the whole play.When âthe deedâ is done, Macbeth says: âMacbeth does murder sleep â the innocent sleep, Sleep that knits up the raveled sleave of careâ (Act 2, scene 2, Lines 35-36). Sleep is a powerful image of the natural, good and healthy.nother example is the murder of King Duncan, which is essential to the whole play.

C# Interfaces and Inheritance. Using interfaces as in Listing 1 is useful because it allows you to define little pockets of functionality. Any implementing classes can provide the code to fulfill the interface contract. However, the real power of interfaces comes from inheritance, as illustrated in Listing 2. Listing 2 Interfaces and inheritance.
A class can extend one other class and implement any number of interfaces. An interface can extend any number of interfaces. When a class implements an interface it implements all of the methods declared in that interface. You can have variables and parameters of an interface type. method in Java that has a parameter of interface type is nearly the same as a function template in C++. A class that uses interfaces to type any variables or parameters behaves very similarly to a class template in C++. Just think of the interface names as if they were template arguments.
