pentagonal program
















I have to write a program that displays the first 100 pentagonal numbers using different methods. This is what I have so far:
















public class FivePointOne{















public static void main(String[]args){















System.out.println("The the pentagonal numbers are: ");















}















//this method will find the penagonal numbers















public static int getPentagonalNumber(int n){















for(int i = 0; i < 100 ; i++){















if(valueOfEquation(i) % 5 == 0)
















}















//return n;















}















//This method will calculate the numerator















public static int getNumerator(int n){















int N = (n*((3*n)-1));















return N;















}















//This method defines the denominator















public static int getDenominator(int n){















final int d = 2;















return d;















}















//This method will calcualte the equation















public static int valueOfEquation(int n){















int value = getNumerator(N) / getDenominator(d) ;















return value;















}
















}
















But when I compile it to test it out I receive the error message "Illegal start of expression," ';' expected, and "reach end of file while parsing". Can anyone explain to me what is going on and how to fix it so?
