Question

Chapter 6, Problem 6.1PE

Expert Solution & Answer

Program Plan Intro

Program Plan:

Declare the class “Penta”
Definition for main class
- Use for loop to iterate the variable “j” equals to “100”.
- Check whether “j” mod “10” equals to 0.
  - Call the method “getPentagonalNumber()”.
- Otherwise, call the method “getPentagonalNumber()” concatenate with space.
Method definition for “getPentagonalNumber()”
- Return “n * (3 * n - 1) / 2”.

Program Description Answer

Program to display first 100 pentagonal numbers with 10 numbers on each line using the method “getPentagonalNumber ()”

Explanation of Solution

Program:

//Definition for class "Penta"

public class Penta

{

//Definition for main class

public static void main(String[] args)

{

//For loop to iterate the variable

for (int j = 1; j <= 100; j++)

//Check whether the variable "j" mod 10 equals to "0"

if (j % 10 == 0)

//Call the method "getPentagonalNumber"

System.out.println(getPentagonalNumber(j));

else

//Call the method "getPentagonalNumber"

System.out.print(getPentagonalNumber(j) + " ");

}

//Method definition for "getPentagonalNumber"

public static int getPentagonalNumber(int n)

{

//Return the result

return n * (3 * n - 1) / 2;

}
