Java Using Arguments in a Complex Formula -

i new java, , reading book on now. book not give me answer. using following code:

package loanpayments;  public class loanpayments {      public static void main(string[] args) {         double years = double.parsedouble(args[0]);         double p = double.parsedouble(args[1]);         double r = double.parsedouble(args[2]);          double r = r / 100;          double = p*(math.e*math.exp(r*years));          system.out.println(a);     }  } 

i testing code following values:

• years = 3
• p = 2340
• r = 3.1

first have divide r 100 correct value (in case becomes 0.031). new value of 0.031 becomes capitalized r. use formula find a.

i getting incorrect output of ~6980.712, when output should instead ~2568.060.

i thinking put in formula wrong, should this:

pe^r(years)

in case e euler's number (~2.71828)

if advise me on how fix formula, or other mistake, appreciate it, thanks.

not needed multiply e because math.exp() exponential function.
