Please write Java codes to solve the following questions. The submissions should be your source codes and screen-shots of the program results. 1. Write a Java class, Flower, that has three instance variables of type String, int, and float, which respectively represent the name of the flower, its number of petals, and price.

That is, it returns an array c of length n such that c[i] = a[i]b[i], for i = 0,...,n-1. (10 points) 3. What are some potential efficiency disadvantages of having very deep inheritance trees, that is, a large set of classes, A, B, C, and so on, such that B extends A, C extends B, D extends C, etc.?
