Program Plan Intro

Class “SequentialIncrementer”

Program plan:

  • Create an interface “Incrementable”,
    • Declare the methods “increment()”, and “getValue()”.
  • Create a class “SequentialIncrementer” that implements an interface “Incrementable”,
    • Declare the variable.
    • Define the constructor to assign the initial value.
    • Define the method “increment ()” to increase the value by “1”.
    • Define the method “getValue ()” to return the current value incremented.
    • Define the method “main()”,
      • Construct “SequentialIncrementer” object.
      • Call the method “increment()”.
      • Print the value returned from the method “getValue()”.

Program Plan Intro

Class “RandomIncrementer”

Program plan:

  • Create an interface “Incrementable”,
    • Declare the methods “increment()”, and “getValue()”.
  • Create a class “RandomIncrementer” that implements an interface “Incrementable”,
    • Declare the variable.
    • Declare the “Random” variable.
    • Define the constructor to assign the initial random value.
    • Call the method “increment ()”.
    • Define the method “increment ()” to change the value with new random integer.
    • Define the method “getValue ()” to return the current value updated.
    • Define the method “main()”,
      • Construct “RandomIncrementer” object.
      • Print the value returned from the method “getValue()”.

Methods (Ch6) - Review 1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java. There are two methods, method #1 which calculates the square root for positive integers, and method #2, which calculates the square root of positive doubles (also works for integers). public class SquareRoot { public static void main(String[] args) { } // implement a loop of your choice here // Method that calculates the square root of integer variables public static double myRoot(int number) { double root; root=number/2; double root old; do { root old root; root (root_old+number/root_old)/2; } while (Math.abs(root_old-root)>1.8E-6); return root; } // Method that calculates the square root of double variables public static double myRoot(double number) { double root; root number/2; double root_old; do { root old root; root (root_old+number/root_old)/2; while (Math.abs (root_old-root)>1.0E-6); return root; } } Program-it-Yourself: In the main method, create a program that…
