Java 程序无法启动,取款/存款方法
我不熟悉方法和类。 我编写了一个取款/存款程序,要求输入姓名和余额,允许取款和存款功能。eclipse不允许我运行程序,为什么会这样??我是否要在单独的类上创建公共静态void主字符串[]args??如果有必要的话,有什么方法可以让我留在这个班上或者转到主班Java 程序无法启动,取款/存款方法,java,class,methods,main,Java,Class,Methods,Main,我不熟悉方法和类。 我编写了一个取款/存款程序,要求输入姓名和余额,允许取款和存款功能。eclipse不允许我运行程序,为什么会这样??我是否要在单独的类上创建公共静态void主字符串[]args??如果有必要的话,有什么方法可以让我留在这个班上或者转到主班 import java.util.Scanner; public class bank { private String name; private double balance; private double withdraw; pri

请从基本的Java开始。您需要有一个主方法来执行java程序。eclipse不允许我运行该程序,为什么会这样 因为JVM无法找到main方法 我是否要在单独的类上创建公共静态void主字符串[]args 不可以。您可以在同一个类中添加主
