Chapter 8, Problem 8.25PE

Program Plan Intro

Markov matrix

Program Plan:

• Include the package “java.util.Scanner” into program.
• Define the class named “Exercise08_25”.
  • Define the main method.
    • Define the scanner object “obj” to get input from user.
    • Declare and initialize a final variable “N” in type of integer.
    • Prompt the user and declare the two dimensional variable “arr” in type of “double”.
    • Using “for” loops, get input values for array “arr[][]”.
    • Call the method “isMarkovMatrix()” which pass the “arr” as argument in “if” condition.
      • Print appropriate statement on screen.
  • Define the “isMarkovMatrix()” Boolean method which pass two dimensional array “m[][]” as argument.
    • Using “for” loops and “if” condition, check the value of “m[][]” is less than “0”.
      • If the condition is true, return “false”.
    • Using “for” loop, add column values of matrix and return “true” if the value of “tot” equal to “1”. Otherwise return “false” to calling function.
