7. A friend of yours is having trouble instantiating an object of type Figurelnterface. His code includes the statement: Figurelnterface myFig = new Figurelnterface (27.5); What do you tell your friend? 8. Draw figures representing our abstract view of the structures created by each of the following code sequences. Assume that each case is preceded by these three lines of code: LLNode < String > node1 = new LLNode < String > ("alpha"); LLNode < String > node2 = new LLNode < String > ("beta"); LLNode < String > node3 = new LLNode < String > ("gamma"); a. node1.setLink(node3); node2.setLink(node3); b. node1.setLink(node2); node2.setLink(node3); node3.setLink(node1); c. node1.setLink(node3); node2.setLink(node1.getLink();
