在类X中找不到 main 方法怎么处理？

Question

import java.text.NumberFormat;public class Account { private final double RATE = 0.035; private long acctNumber; private double balance; private String name; public  Account (String owner,long account,double initial) {  name = owner;  acctNumber = account;  balance = initial; } public double deposit (double amount) {  balance = balance + amount;  return balance; } public double withdraw (double amount, double fee) {  balance = balance - amount - fee;  return balance; } public double addInterest() {  balance+=(balance * RATE);  return balance; } public double getBalance() {  return balance; } public String toString() {  NumberFormat fmt = NumberFormat.getCurrencyInstance();  return acctNumber + "\t" + name + "\t" + fmt.format(balance); }}错误: 在类 study3.Account 中找不到 main 方法, 请将 main 方法定义为:   public static void main(String[] args)否则 JavaFX 应用程序类必须扩展javafx.application.Application

在当前类中写上一个main方法，main方法是Java应用程序的入口
