Approach: In java, the main use of the "this" keyword is to refer to a current class instance variable. Whenever there is a conflict between the parameter and instance variables then this problem can be solved by the keyword "this". The following code: public void setNumDays(int numDays) { this.numDays = numDays; }Complete java code: import java.util.Scanner; class CablePlan { private int numDays; // FIXME: Define setNumDays() method, using "this" implicit parameter. public void setNumDays(int numDays) { this.numDays = numDays; } public int getNumDays() { return numDays; }}// ===== end ===== // ===== Code from file CallCablePlan.java =====public class CallCablePlan { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); CablePlan house1Plan = new CablePlan(); int userNum; userNum = scnr.nextInt(); house1Plan.setNumDays(userNum); System.out.println(house1Plan.getNumDays()); }}// ===== end ===== Output

For this assignment you will be building on the Fraction class you began last week. All the requirements from that class are still in force. You'll be making five major changes to the class. Delete your set() function. Add two constructors, a default constructor (a constructor that takes no parameters) and a parameterized constructor (a constructor that takes parameters). The default constructor assigns the value 0 to the Fraction. In the parameterized constructor, the first parameter will represent the initial numerator of the Fraction, and the second parameter will represent the initial denominator of the Fraction. Since Fractions cannot have denominators of 0, the default constructor should assign 0 to the numerator and 1 to the denominator. Also, the parameterized constructor should check to make sure that the second parameter is not a 0 by using the statement "assert(denominatorParameter != 0);". To use the assert() function you'll also need to #include <cassert>. (Note, I…
