Hello guys!
I'm working on a network application for my class. Basically I have to write java and jsp to make a site that gives the .jsp output below (which is preceded by a .jsp page that asks for the balance, rate, and period). I'm writing the java for it now and I'm trying to make a html table with the java class.
The problem I'm having is to make it so that the table is showing the standard deviation of 2 for the rate (rows) and period (columns). Instead of just adding all of the information for all periods and rates. How do I narrow it?
note: I know the code in my table is really not correct at all, i think everything else is ok though
My Code so far: Thanks.
package SavingAcct;
import java.text.*;
public class savingsAccount {
private double rate;
private double currentBalance;
private int term;
public savingsAccount() {
this.rate = 0.00;
this.currentBalance = 0.00;
this.term = 0;
}
public savingsAccount(double rate, double currentBalance, int term) {
this.rate = rate;
this.currentBalance = currentBalance;
this.term = term;
}
