Java“java.lang.NoSuchMethodError：main”

Question

根据我对错误的理解，最常见的原因是因为我没有包含“public static void main（String [] args）”，但是在发现错误之前我已经完成了这个，这让我感到难过。 谁能帮我吗？

import java.io.*;
class basketBall
{
    private String name;    
    private double number;
    private String team;

    // declare getter method public
    public String getName()
    {
        return name;
    }

    // declare setter method public
    public void setName(String n)
    {
        name = n;
    }

    // declare getter method public
    public String getTeam()
    {
        return team;
    }

    // declare setter method public
    public void setTeam(String t)
    {
        team = t;
    }

    // declare getter method public
    public double getNumber()
    {
        return number;
    }

    // declare setter method public
    public void setNumber(double num)
    {
        number = num;
    }

    // declare dribble method
    void dribble()
    {
        System.out.println (name + ", " + number + " dribbles down the court...");
    }

    // declare shoot method
    void shoot()
    {
        System.out.println (name + " shoots... And he scores, for the " + team + "'s!");
    }
}

// test class for basketBall class
class basketBallTester
{
    public static void main (String[] args)
    {
        //construct player and fills in its objects 
        basketBall Player1 = new basketBall();
        // fill in objects of player1
        Player1.setName("Ethan");
    Player1.setTeam("Vikings");
    Player1.setNumber(15);

        // call methods
        Player1.dribble();
        Player1.shoot();
    }
}

您可以通过多种方式运行程序。 其中之一是：

1. 创建一个单独的basketBallTester.java文件，并在其中放置您的类basketBallTester 。
2. 编译这两个文件： basketBallTester.java和basketBall.java
3. 使用java basketBallTester运行程序
