It is going to represent a term in polynomial expression. It has an integer coefficient and an exponent. In this case, there is only 1 independent variable that is 'x'. There should be two operations for the Term: public Term times(Term t) - multiplies the term with another term and returns the result public String toString() - prints the coefficient followed by "x^" and appended by the exponent. But with the following additional rules: if the coefficient is 1, then it is not printed. if the exponent is 1, then it is not printed ( the caret is not printed as well) if the exponent is 0, then only the coefficient is printed. Input The first line contains the coefficient and the exponent of the first term. The second line contains the coefficient and the exponent of the second term. 1·1 4·3 Output Display the resulting product for each of the test case. 4x^4For the following four classes, choose the correct relationship between each pair. public class Room ( private String m type; private double m area; // "Bedroom", "Dining room", etc. // in square feet public Room (String type, double area) m type type; m area = area; public class Person { private String m name; private int m age; public Person (String name, int age) m name = name; m age = age; public class LivingSSpace ( private String m address; private Room[] m rooms; private Person[] m occupants; private int m countRooms; private int m countoccupants; public LivingSpace (String address, int numRooms, int numoccupants) m address = address; new int [numRooms]; = new int [numOceupants]; m rooms %3D D occupants m countRooms = m countOccupants = 0; public void addRoom (String type, double area)
