import java.util.Scanner;

// 程序从这里开始执行
public static void main(String[] args)

double mealCost, tax, mealCount, subtotal, total;
Scanner keyboard = new Scanner(System.in);
System.out.println("该程序将显示小票，显示购买金额、税费和总费用。");
System.out.println("一顿饭的费用是多少？");
mealCost = keyboard.nextDouble();
System.out.println("顾客购买了多少顿饭？");
mealCount = keyboard.nextDouble();
subtotal = mealCost * mealCount;
tax = 7.5 * subtotal;
total = subtotal + tax;
System.out.print(total % 5.2);
// TOTAL 以美元计算
}
}
每次我尝试编译这段代码时，都会收到一个错误消息：
> fourthProgram.java:13: 错误: 缺少方法体，或声明为抽象
public static void main(String[] args);
我是 Java 新手。

Every time I attempt to compile this code I receive an error saying:
> fourthProgram.java:13: error: missing method body, or declare abstract
public static void main(String[] args);
I am new to Java.
