Add the following method to the TimeSpan class: public void add(TimeSpan span)
Adds the given amount of time to this time span.
Recall the TimeSpan code from this chapter:
public class TimeSpan {
private int hours;
private int minutes;
public void add(int hours, int minutes) { ... }
public int getHours() { ... }
public int getMinutes() { ... }
public String toString() { ... }
// your code goes here
}

The animal classthis class represents a an animal residing at a zoo. it has a weight (in pounds),height (in inches), a name, and a color. the methods in the class include constructors, getters, and a tostring. you will finish the implementation of these methods. referto the code documentation.1.getters: you will need to implement getter methods. these get a value (froma member variable) in the animal class. you will make a getter method toreturn each variable (weight, height, name, color). reference getname if youare having issues.2.tostring: you will need to finish the tostring method. this returns a stringcontaining information about an animal. the output string should be of theformat: ” (name) , a ( color )â’colored animal . ( weight ) pounds , ( height ) inches .\n”the height and weight are formatted to 1 decimal place. recall from lab 1how to format strings neatly using string. see the reference sectionfor more about string. format.

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?
